M6‑1.00 x 20mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications that require added reach and high mechanical strength, this M6‑1.00 x 20mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 20mm length allows for deeper thread engagement to improve joint security in machinery and mechanical assemblies. Its rounded, low‑profile button head reduces snag points while maintaining a clean, professional appearance, and the internal hex drive enables controlled torque application. Finished with a thermal black oxide coating, it offers reduced glare, mild corrosion resistance, and a durable technical finish suitable for industrial and precision mechanical use.
