Professional Applications & Engineering Value

This M5 set screw is engineered for demanding applications where precise axial location and permanent fastening are critical. The zinc-plated alloy steel construction provides excellent corrosion protection, making it ideal for machinery, automotive assemblies, and electrical enclosures exposed to moisture. The 90° cone point bites securely into shafts and hubs, preventing slippage and maintaining alignment under high rotational forces and vibration. Its headless design and hex drive allow for a clean, flush finish, essential in pulleys, gears, and collars where protruding fastener heads are not feasible. Meeting DIN 914 and ISO 4027 specifications, this metric set screw delivers consistent performance and interchangeability, reducing assembly time and ensuring long-term reliability in precision engineering projects.

Specification Summary & Compliance

This set screw features an M5 x 0.8 mm coarse thread with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and reliable engagement.
