M16‑2.00 x 45mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Engineered for high‑strength metric fastening in heavy‑duty applications, this M16‑2.00 x 45mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The 45mm length provides substantial thread engagement for secure clamping in thick or structural assemblies, while the low‑profile button head delivers a smooth, streamlined appearance in exposed installations. An internal hex drive allows for controlled torque application, and the thermal black oxide finish reduces glare, offers mild corrosion resistance, and provides a consistent technical surface suitable for industrial, machinery, and structural use.
