Metric Standard Socket Head Cap Screws

When a joint has to stay tight in compact spaces, metric socket head cap screws bring the clamp load. These Class 12.9 alloy screws meet ASTM A574M and ASME B18.3.1M for serious strength, with black oil dip or zinc plate for added corrosion resistance. Need rust-proof? Go 18-8, step up to 316 for harsher washdown.
