RAMPA© M8 Threaded Insert 18mm

M8 Insert 14mm Diameter x 18mm Long x 8M Internal Thread

RAMPA Inserts feature a sealing collar, hex drive, tilt protection and speed-up of assembly.  Optimal retaining function, works for widest range of substrates and has 100% control of all functional dimensions including internal machine thread. Patent awarded. Made in Germany.

These steel zinc plated inserts are machined. With three starting threads they sit straight in the hole (like a three legged stool) and therefore easily insert squarely.  Comparatively, most other insert brands are cast resulting in a more brittle insert and one thread that is very difficult to install squarely.

Use a 1/2" diameter drill for the pilot hole and an 8mm Allen key for insertion.

Compatible with RAMPA M8 Bolts.

Available in packs of 1, 10, 50.

Tip: In our shop, for securing metal table legs to the table top, we found the M8 inserts have a much better grip retention than the M6 inserts.

I used these to attach C-Channels to a live edge table top. High quality. The best insert hardware I've ever come across.

Best I've Found

These M8 and M6 inserts are the best I've found. Easy to insert and sturdy. Nice that Black Forest Wood Co. sells the inserts and matching bolts for each size.

Awesome holding strength

I used 4 of these on a guitar neck to replace the standard wood screws my guitar was built with to hold the neck to the body. Not only were these incredibly easy to install, they make neck and body much tighter to eachother and as a whole the guitar gained a ton of resonance and even tone! 100% will be buying more and doing this to all my bolt on guitars.
