DIN 912 M2x4mm Socket Head Cap Screw - A2 Stainless Steel (304)

The DIN 912 M2 socket head cap screw is a miniature fastener designed for high-precision applications where space constraints, corrosion resistance, and reliable torque transmission are critical. Manufactured from A2 stainless steel (AISI 304), this screw is non-magnetic, corrosion-resistant, and suitable for indoor and semi-corrosive environments. The clean cylindrical head profile and internal hex drive (Allen) allow for high tightening force without stripping or cam-out-ideal for tight-space assemblies.

Technical Specs:

• Standard: DIN 912 / ISO 4762 - metric socket head cap screw
• Thread Size: M2 × 0.4 mm pitch - fine precision thread
• Head Type: Cylindrical head with hex socket (Allen drive, 1.5 mm)
• Material: A2 stainless steel (AISI 304) - corrosion resistant and non-magnetic
• Finish: Natural, passivated stainless steel
• Tensile Strength: Approx. 500-700 MPa
• Tight tolerances - ideal for precision mechanical assemblies
