M8-1.25 (metric) 316 / A4 marine-grade stainless steel hex socket head cap screws (Allen head), partially threaded, DIN 912 / ISO 4762. 316 stainless adds molybdenum for markedly better resistance to salt water, chlorides and pitting than 18-8 / A2 — the right choice for marine, coastal, pool and chemical service. 6mm hex socket drive with a cylindrical cap head. Partially Threaded across all lengths in this listing (35mm to 100mm). Thread length b = 28mm (2d + 12mm per DIN 912); the balance of the shank is unthreaded. Sold in production-volume bulk packs.
