Professional Applications & Engineering Value

This M5 brass set screw delivers exceptional engineering value through its carefully selected material properties and precision manufacturing. The brass construction provides natural corrosion resistance, making it ideal for electrical components, marine equipment, and plumbing systems where moisture resistance is critical. The headless slotted design with flat tip ensures secure fastening of pulleys, gears, and knobs onto shafts without protruding hardware. The coarse thread pitch (0.8mm) combined with Class 6g tolerance enables quick installation in production environments while maintaining vibration resistance. These metric set screws are particularly valuable in precision machinery, automotive assemblies, and electronic enclosures where reliable, flush-mount fastening solutions are essential for long-term performance.

Specification Summary & Compliance

This precision fastener features M5 x 0.8mm coarse thread with Class 6g thread fit according to ISO metric standards, ensuring dimensional accuracy and proper engagement.
