M6‑1.00 x 20mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening where additional thread engagement and corrosion protection are required, this M6‑1.00 x 18mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 18mm length provides secure clamping in machinery and mechanical assemblies, while the smooth, low‑profile button head delivers a clean, finished appearance in exposed or clearance‑restricted applications. Featuring an internal hex drive for precise torque control, it is finished with a zinc‑baked coating and trivalent chromium (Cr+3) passivation to enhance corrosion resistance and reduce the risk of hydrogen embrittlement—making it well suited for industrial, automotive, and mechanical use.
