Professional Applications & Engineering Value
This M4 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The headless design allows flush mounting in tight assemblies, while the cup point tip creates permanent seating by indenting into shaft materials. Manufactured from 18-8 stainless steel, it maintains integrity in corrosive environments common to machinery, automotive, and electronic enclosures. The Class 6g thread fit ensures precise mating with tapped holes, eliminating play in precision assemblies. Combined with serrations under the head, this metric hex socket set screw provides reliable anti-rotation performance that withstands continuous operational stresses, making it ideal for securing gears, pulleys, and collars in demanding mechanical systems.
Specification Summary & Compliance
This metric set screw features M4x0.7mm coarse threads with Class 6g tolerance per ISO metric standards, ensuring interchangeability with industry components. The 4mm length and 2mm hex drive provide standardized installation across applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing restricted substance compliance for global industrial use.
