Accu supplies precision screws to engineers, manufacturers and maintenance teams right across the UK. Cap head, button head, countersunk, pan head, shoulder, grub and hexagon head. If it has a thread and a head, there is a good chance Accu stocks it.

Sizes run from tiny M1.2 threads for electronics and instrumentation up to M30 for heavy machinery, with lengths from 2mm to 300mm. That covers prototype benches, production lines and plant rooms alike.

Material choice matters, so the range goes well beyond plain steel. A2 and A4 stainless for corrosion resistance. Titanium where weight is critical. PEEK, nylon, polycarbonate and other engineering plastics where you need electrical insulation, chemical resistance or a lighter assembly. Aluminium screws are in there too.

Specialist types include captive and captive panel screws, security screws, sealing screws with O-rings, vented screws for vacuum work, thread forming screws and SEMS screws with pre-assembled washers.<

Accu can also finish screws to order. AccuBlack chemical blackening gives a matte, low-reflection finish, and AccuLock pre-applied thread locking patches help stop screws backing out under vibration.

Based in Huddersfield, Accu ships fast to businesses throughout the UK, with express and timed delivery options. Need something that is not on the shelf? Their custom manufacture service produces bespoke screws to drawing, from small prototype runs to full production volumes.
