Product Description

The M3x22 cylindrical head hexagon socket screws, also known as cylindrical head Allen screws or hexagon socket head screws, feature a DIN 912-compliant cylindrical head with an M3 thread diameter and 22mm length. Designed for high-torque applications in electronics, automotive, and machinery assembly, these screws utilize a 2.5mm hex key (Allen) drive for secure fastening. Typically manufactured from grade 12.9 alloy steel or stainless steel (A2/A4), they offer tensile strengths up to 1,200 MPa and operate within -50°C to +150°C temperature ranges. The compact head design enables installation in confined spaces while maintaining a torque range of 1.2-1.5 Nm for reliable clamping force. Surface treatments including zinc plating or black oxide coating provide corrosion resistance for industrial environments. Their key advantages include space efficiency and precise axial alignment, though frequent retightening may wear the hex socket over time.
