How do you straighten a bent lead screw?
One can straighten a screw, simply by locating the center of the bend, and pressing down on the high point while two points the same distance apart from the center of the bend are supported on cushioned blocks.
How do you fix misaligned anchor bolts?
If the anchor bolts are majorly misaligned (more than a few inches), an engineer may decide to cut off the rods and drill in anchor rods and use epoxy that aligns with your area’s building code. An engineer should be careful to ensure the foundation hasn’t been compromised if going this route.
Is it possible to straighten a lead screw? And how.
Misaligned anchor bolts can be a major headache. Many industries use anchor bolts to attach structural members, usually steel, to concrete for stability. One end is embedded in concrete while the other is attached to the steel structure. Installation of anchor bolts requires accuracy, but sometimes anchor bolts get misaligned during installation. This problem can be extremely difficult to fix, but the question remains: can you fix a misaligned anchor bolt?
As with most complex questions, the answer is not a simple yes or no. There are many questions to consider when determining whether a misaligned anchor bolt can be fastened:
When was the problem noticed?
Is the entire anchor bolt pattern misaligned?
Have you consulted your surveyor and engineer?
It should be noted that the last question is the most important. When something goes wrong on site, constant communication is key. You may be more concerned with acting quickly before the concrete sets the anchor bolts, but communicating with experts should always be your first line of defense.
Quick Tip: Surveyors and field technicians are great at supervising bolt placement, and some will even place anchor bolts for you. Finding a reputable surveyor and field technician for your next project is a great way to avoid mistakes on the job site.
Setting an anchor bolt
To avoid misalignment of an anchor bolt, it is important to follow the American Institute of Steel Construction (AISC) code of practice and have technically skilled team members on site. According to the AISC, a field survey of the proposed anchor bolt positions must be carried out prior to the delivery of the steel. Having a team of highly trained professionals locating and placing the concrete helps eliminate misaligned anchor bolts, downtime and unnecessary labor and expense.
Remember the old adage “measure twice, cut once?” This strategy also applies to structural steel. Keeping careful eye on the measurements will ensure you don’t misalign your anchor bolts. Using a template can help with accuracy and ensure you use the correct pattern before attaching it to the base. Approximating positions instead of measuring them accurately creates problems. Making sure you have the right template in the right place is the best practice.
Dealing with misaligned anchor bolts
Due to installation problems, misalignment occurs from time to time. As mentioned, repair methods vary depending on the time, location, and severity of the problem.
If you discover a misaligned anchor bolt before the prop base plate has been installed, it may be possible to use a different pattern or plate. This is ultimately the engineer’s decision, so it’s important to consult an engineer if problems arise. If the anchor bolt is misaligned after the column is set, you can usually slot the baseplate and use a washer to bridge that slot.
If the anchor bolts are severely misaligned (more than a few inches), an engineer may decide to cut the rods and drill in anchor rods and use epoxy that conforms to your area’s building code. An engineer should be careful not to compromise the foundation when going this route.
Ultimately, if you find misaligned anchor bolts during your installation process, communicating with experts is the top priority. Your technicians can troubleshoot the issue and determine if repairs are possible. You can always consult the AISC guides and regulations for more information.

To remove a stuck bolt, spray some penetrating oil such as WD-40 around the head of the bolt. Let the oil sit for about 20 minutes to allow it to lubricate the threads on the bolt and make it easier to remove. Then take a box wrench and slide a hollow metal rod over the handle so you can increase the length and give you more torque to turn the wrench. Slip the wrench over the head of the stuck bolt and hold it at the very end of the rod. Pull firmly on the end of the rod to try to loosen the bolt. After the screw loosens, slide off the hollow metal rod and continue turning the wrench until the screw is removed.

Save an Irreplaceable Screw
When my friend said his gunsmith was not helpful in either identifying the screw threads or offering a replacement screw, I took his word and went from there. The gun is US made. Metric threads were not used in the US when this gun was manufactured. I would also be surprised if an imperial thread was used. I would think that maybe the manufacturer used their own thread to discourage owners from tinkering with or modifying the gun. I just do not know. I’m just glad we were able to recover the screw so easily. I wish I had taken a before and after photo of the actual bolt on the gun. The difference was pretty striking. Thanks for your comment.
How to Remove a Broken Bolt
In theory, metal screws – male-headed fasteners that fit into appropriate non-tapered nuts – can be removed and even reinstalled if necessary. Unfortunately, if overtightened or otherwise forced, screws can seize and break, making removal a challenge. Are you wondering how to remove a broken bolt before you continue with your home construction or patio building project? With the right equipment and technique, a broken bolt can be successfully pulled out so you can insert a new one.
STEP 1: Strike the center punch of your broken bolt.
Place the center punch as close to the center of the broken bolt as possible. Hit it directly with the hammer to create a starting point for drilling a pilot hole. A precise pilot hole is critical so you don’t damage the threads of the broken bolt when pulling it out. If the thread on the screw or screw hole is damaged, it may make it impossible to remove the screw. In addition, if the thread on the screw hole is damaged, you may not be able to use a new screw after the old one is pulled out.
STEP 2: Slowly use a left-handed drill to create a pilot hole.
Check the chart on your extraction kit to select the correct size left-handed drill (also known as the “reverse drill”) to drill a pilot hole in this broken bolt. Unlike traditional drill bits, which are considered right-handed and have clockwise threads, left-handed bits are designed with left-hand threads. This provides a better bite when using your drill bit in reverse to remove a fastener.
Pro Tip: If you’re buying a kit for the job, invest in quality; The last thing you need is a cheap set of teeth breaking during this process.

Set your drill in reverse and as slow as possible (ideally 20 rpm) and use the left-handed drill bit. The torque of reverse drilling (i.e. counter-clockwise) prevents you from further tightening the threads on the screw. Now place the drill over the center punch mark you made and, holding the drill, slowly drill a small pilot hole in the screw, about ¼ inch deep.
Hopefully, back-drilling your pilot hole will loosen the screw enough that you can use vise pliers to remove the screw. Remember, “right tight, left loose” – turn the screw to the left (counterclockwise) to remove. If the screw has not loosened at all, continue to step 3 to extract it.
STEP 3: Switch to an extraction bit.
For a stubbornly stuck bolt, you’ll need an extraction drill. Consult your extraction kit chart for the correct bit size for the screw size. The extraction drill is also a left-handed drill (but with a different purpose), so you’ll still use the reverse drill setting. Swap the first drill for the extraction drill in your drill, insert it into the pilot hole and gently tap your drill and the drill with a hammer.
STEP 4: Slowly drill backwards to remove a broken bolt.
Still use a very slow reverse drill setting, e.g. B. 20 RPM and start drilling into the pilot hole. Slow and gentle is key here: the drill bit is likely hardened steel, and if it breaks during this process, you’re in for an even more difficult extraction. The broken bolt should soon “grab” the extraction drill bit and start pulling out as you drill backwards. Continue slowly and steadily until the entire screw is fully extracted, ideally saving the threads so you can insert a new screw. phew!

STEP 5: Use a magnet to remove any metal filings left by the broken bolt.
Any metal shavings or shavings left in the threaded hole must be removed before installing a new screw. Place a strong magnet over the hole to attract the loose bits, or use compressed air to blow the threads clean. Do not skip this step or a new screw could seize or snap off.
The best practice you just learned should safely remove any broken bolt while also ensuring that you can reuse the hole to insert a new one later. If not, contact a local welding shop who should have the skills and tools to remove a broken bolt. And remember to insert all screws slowly and carefully in the future to avoid seizing and breaking off the upper part of the screw.
Is it possible to straighten a lead screw? And how.
Hello folks. I have a problem with the progress of the second version of my DIY CNC router and am looking for advice from experienced people.
Some time ago I bought two 1 m long DIN103 14×4 trapezoidal threaded rods and put them aside. Now it’s time to mount the longest one (750mm) for the Y axis. I took one to a lathe operator to make the bearing neck and thread for the axial lock – 9mm for two style 629 (ID 9, OD 26mm) bearings. The other end is supported only by a larger bearing (6003 – 17mm ID) and a Delrin bushing.
Mounted and it seemed fine. But there is a noticeable increase in power that repeats itself with every twist when twisted by hand. No drive nuts fitted, rod only on two opposite support bearings and axially secured on one of them.
I had another idea to make the bearing retainer – using the same 6003 bearing on both ends, a brass bushing and split collars on the bolt to secure it axially. (because it depends very much on the quality of the lathe, the turner and his will to achieve as little radial play as possible with a 9 mm neck).
Today I tested this option and it got even worse. I assume because the larger bearing resists wobble better. The bars are anything but straight. Apparently I randomly took the one with less play first. The other, when fixed in the same way, is simply tragic.
The bars are made by rolling and the steel is soft (C15 in local denomination). Can you fix them or do I have to look for new ones?
Thanks in advance.
Ivan
