• Optimized thread engagement through M3 coarse thread (0.5 mm pitch) with Class 5g6g fit, facilitating quick assembly and vibration resistance.
• Maximum thread coverage with fully threaded design, distributing clamping force evenly across the entire 5 mm length.
• Enhanced durability from Rockwell C37 hardness, maintaining structural integrity under repeated loading cycles.
• Global compliance assurance meeting DIN 912/ISO 4762 standards with RoHS 3 and REACH environmental regulations.

Professional Applications & Engineering Value

Engineered for precision assemblies requiring high-strength fastening solutions, these M3 socket head cap screws deliver exceptional performance in machinery, automotive components, and industrial equipment. The zinc-plated alloy steel construction provides critical corrosion protection where exposure to moisture or chemicals is a concern, while the Class 12.9 strength rating ensures reliable operation under extreme mechanical loads. The 2.5 mm hex drive allows for compact installation in confined spaces without compromising torque application, and the coarse thread design (0.5 mm pitch) enables rapid assembly while maintaining vibration resistance. These metric screws are particularly valuable in applications demanding precise alignment and repeated disassembly, where DIN 912/ISO 4762 compliance guarantees dimensional accuracy and interchangeability.
