Designed for high‑strength metric fastening where controlled length and durability are essential, this M12‑1.75 x 45mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The 45mm length delivers reliable thread engagement for secure clamping in structural and heavy mechanical assemblies, while the low‑profile button head helps reduce snagging and maintains a clean, finished appearance in exposed applications. 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 provides a consistent technical finish suitable for industrial and machinery use.
