M6‑1.00 x 45mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Engineered for metric fastening applications that demand extended length and high tensile strength, this M6‑1.00 x 45mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 45mm length allows for deep thread engagement in thicker or multi‑layer assemblies, ensuring strong, reliable clamping. Its low‑profile button head helps maintain a clean, streamlined appearance while reducing snag points in exposed installations. Featuring an internal hex drive for precise torque application, it is finished with a thermal black oxide coating that reduces glare, provides mild corrosion resistance, and delivers a durable technical finish suitable for industrial and precision mechanical applications.
