Brass #8-32 1 1/2" Long Electric Guitar Neck Bolts with .394" Threaded Inserts

Description

There are two sets of screws because you should use the stainless steel ones first to postion your neck and torque it down. Then replace one by one with the brass screws.
Make sure you measure first to figure out how long of a bolt you need.
Choose the right size!!
This listing is for a set of 4 Brass Screws and 4 Stainless Steel machine screws  1.5" long
They are just like their wood screw counter part.
It also includes 4 threaded inserts that can be driven in by 5/32 or 4mm Allen wrench
The hole size recommended is 15/64"
These work best with hard woods. Some people like to add epoxy or glue to ensure they never go anywhere.
If you know what your doing you sure can use some glue to keep them in place forever.
I don't use glue and never had to.
The threaded inserts are .394" long.  be sure to drill your hole deep enough to accept any extra threads that go past the insert.
Be sure to just measure, these might not be long enough
I took my dremel drill and hit the top of the screw with some compound.  There might still be some in the head of the screw. Clean up after install.
This is the same thing I do for my builds. I touch the top with the dremel to shine it up and then use the stainless steel bolts first to properly seat the neck.
