M8‑1.25 x 35mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications that require extended length and high mechanical strength, this M8‑1.25 x 35mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 35mm length provides deep thread engagement for secure fastening in machinery and structural assemblies, improving joint stability under load. Its low‑profile button head offers a smooth, finished appearance while reducing snag points in exposed or clearance‑restricted installations. Featuring an internal hex drive for precise torque application, it is finished with a thermal black oxide coating that reduces glare, offers mild corrosion resistance, and delivers a durable technical finish suitable for industrial and mechanical use.
