Penelope Z. ★★★★★

The hex socket drive on these M20 screws grips my Allen key without any wobble, and the black oxide finish feels tough right out of the bag. I used them to bolt down a steel jig frame and they torqued down smoothly with the partial thread biting exactly where I needed. These will last through a lot

Alexander E. ★★★★★

The partial threading on these 280mm screws made alignment in my fixture much easier than with fully threaded bolts. The black oxide finish seems durable and the hex socket gripped snugly with no cam-out.

Michael ★★★★★

I needed heavy-duty fasteners for a jig build, and these M20-2.5x280mm screws threaded in smoothly with no binding. The black oxide finish looks durable and professional.
