S-91210A230 M5 x 16 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point design that bites into mating surfaces for secure, permanent component positioning
• Exceptional durability thanks to alloy steel construction with Rockwell C45 hardness, resisting deformation under heavy loads
• Space-saving headless design allows for flush mounting in confined spaces where protruding fastener heads aren't feasible
• Quick and secure installation with 2.5mm hex drive that provides excellent torque transmission without cam-out issues
• Reliable thread engagement with Class 5g6g thread fit ensuring precise, vibration-resistant connections in industrial equipment
• Optimized for coarse thread applications where rapid assembly and disassembly are required without compromising strength
• Environmentally compliant construction meeting RoHS 3 and REACH regulations for use in regulated industries worldwide

Professional Applications & Engineering Value

This M5 set screw delivers critical engineering solutions where component slippage and misalignment can cause equipment failure. The alloy steel composition combined with Rockwell C45 hardness ensures the fastener maintains its structural integrity under constant vibration and rotational forces common in machinery, automotive, and precision equipment applications. The 90° cone point angle creates concentrated pressure that securely locks pulleys, gears, and collars onto shafts without damaging the mating surface. As a hex headless set screw with metric coarse threads, it provides the ideal balance of installation speed and holding strength for maintenance-intensive environments. The right-hand thread configuration with 2.5mm hex drive enables straightforward installation in hard-to-reach areas while maintaining the sleek profile required for rotating assemblies.

Specification Summary & Compliance

This precision fastener features M5x0.8mm metric coarse threads with Class 5g6g thread fit tolerance per ISO standards, ensuring consistent performance across manufacturing applications. The 16mm length with cone point tip is manufactured to exact DIN 914 and ISO 4027 specifications for dimensional accuracy and mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms the absence of restricted substances, making it suitable for global industrial supply chains and environmentally conscious manufacturing operations.
