DIN 933 Hex Head Setscrews

≡ ISO 4017
We supply DIN 933 fully threaded hex setscrews in high tensile grades 8.8, 10.9 and 12.9 and stainless steel A2 and A4, from M4 to M48. Thread runs the full length to the head, so the setscrew clamps effectively in tapped holes and thin assemblies where a part-threaded bolt would run out of usable thread.
Also known as: hex setscrew, set screw, fully threaded bolt, hexagon setscrew, tap bolt.
