AMF DIN 6334 Extension Nut - Black, M10 Thread, 17 Mm Hex Key Size

Need a specific nut for connecting T-slot bolts and studs?

This AMF extension nut (DIN 6334) is just what you're looking for.

It's designed to connect T-slot bolts (DIN 787) with studs (DIN 6379), making it super useful for jigs, fixtures, machine setups, or any modular framing system.

The nut has an M10 thread and requires a 17 mm hex key for tightening.

One important note: it's a through-drive type, meaning the thread doesn't go all the way through—so you can't just screw a bolt straight through it.

For proper function and safety, make sure both screws (the bolt and stud) engage at least half the length of the nut on each side.

The minimum recommended engagement depth is one times the thread diameter (so for M10, that's 10 mm).

This black-finished nut is sturdy and reliable, ideal for industrial, workshop, or DIY applications where secure connections matter.

Whether you're building a workbench, a 3D printer frame, or custom machinery, having the right hardware makes all the difference.

This little nut does a big job!
