Workshop Warehouse Setscrews H/T Grade 8.8 M10 X 50 (HSS55)

Description

Genuine Workshop Warehouse · Part no. HSS55

Workshop Warehouse HSS55 is high-tensile hex setscrews, M10 x 50, made to DIN 933 in grade 8.8 zinc plated steel. A 50mm M10 is a handy length for brackets with a spacer, or through a plate to a nut, on cars, vans and trailers; the pack weighs 1.82 kg.

Good to know

• What does DIN 933 grade 8.8 tell me? DIN 933 is the standard for hex-head setscrews, and 8.8 is the usual high-tensile grade, stamped on the head so you can tell it from a soft screw.
• Can it replace a 10.9 bolt? No: where the car's own fixing is marked 10.9 or 12.9, fit the same grade or the maker's part, as an 8.8 screw is weaker.
• Does zinc plating stop rust? It slows it, but it isn't as corrosion resistant as stainless steel; under the car, a smear of copper grease on the threads makes the next removal easier.

Which one?

For the same thread in other lengths, Pearl PHS123B is M10 x 40mm and PHS1070B is M10 x 70mm; for a mixed M6, M8 and M10 box, see Pearl Automotive – Screws Size Assorted (PAT13).
