Can you Retap aluminum?
Sure. You don’t want loose or cross threading bolts to be used to secure anything. Just drill out the existing hole to the desired size, retap, and run in your new locking bolt. It’s a done deal.
How do you fix a stripped thread in metal?
The complete repair for stripped threads is to use a coil-type thread insert. These inserts will give the bolt hole completely new threads which accept the size of the original bolt. In order to use inserts, you must drill the damaged holes slightly larger so that it can take the thread insert.
Will a helicoil hold a head bolt?
yes. in most cases a threadcert such as a helicoil will produce a stronger thread than the original tapped hole. the thing i would be worried about with a ‘cert in a head would be having to oversize the hole to get it in, and possibly running into a water jacket or something.

Can you hammer in a screw?
Yes, a hammer can be used to set a screw into drywall or gypsum, for example. However, the threads of the screw are likely to rip a hole large enough that the screw will just pop back out again!

Why won’t my screws go into the wall?

Why won’t my screws go into the stud?
The primary reason your screw won’t go into the wood is that it’s reached a particularly dense section of wood, and needs a bit more force. To mitigate the issue, drill a larger pilot hole, use a better quality screw, or get a more powerful drill/driver.
How do you remove a screw that spins in wood?
Sometimes using a Torx or flat heat driver bit can get traction and torque to get the screw moving. If that fails, its best to use a screw extractor. Screw extractors have sharp, rough metal threaded tips. These tip burrow into the softer screw head metal, and allow you to apply torque and loosen the screw.
How do I stop my bolts from vibrating loose?
The best way to prevent nuts and bolts from working loose, due to vibrations, is to use a locking device. Some examples of locking devices include flat washers, spring washers, and mechanical screw locking flange nuts.
How do you tighten a carriage bolt that keeps spinning?

Can you tap threads into aluminum?
Aluminum can be drilled at high speeds while still taking deep cuts. In tapping, the feed rate is specified by the pitch of the tap but typically will run as much as 70% faster than a cut thread tap in steel.
Can cast Aluminium be drilled?
“Aluminum is a generally soft, nonferrous, ductile material with low density and naturally high resistance to corrosion. Aluminum is difficult to drill because its ductility and softness causes the material to make constant prolonged contact with the rake face, or cutting edges, of a drill.”Feb 1, 2016.
