ISO 4017 Hexagon Head Screw M12x60 A4 — BOLTON SKU 56534.
About the ISO 4017 Hexagon Head Screw M12x60 A4
The ISO 4017 Hexagon Head Screw M12x60 under this SKU is a fully threaded hexagon-head screw in A4 (316-type) austenitic stainless steel. ISO 4017 covers hexagon head screws threaded up to the head, so the full length is usable for engagement. For the M12 size the standard specifies a 1.75 mm coarse pitch, an 18 mm width across flats and a nominal head height of 7.5 mm, driven with standard 18 mm tooling. At 60 mm long, the screw handles medium-duty structural and equipment fixings — frames, brackets, base plates and flanged joints — where thread engagement is needed along the whole grip, whether into a nut or a tapped member. The A4 grade is the usual specification for coastal, marine and chemically exposed installations, resisting the chloride pitting that attacks plainer grades in the region’s salt-laden air.
