Professional Applications & Engineering Value
This M4 hex headless set screw delivers critical engineering solutions for applications requiring permanent, vibration-resistant fastening. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining Rockwell B80 hardness for durable performance in mechanical assemblies, automation equipment, and precision instruments. The nylon patch thread locker creates a permanent chemical bond that prevents back-out under continuous vibration, eliminating the need for secondary locking mechanisms. With its coarse metric thread (0.7mm pitch) and Class 6g tolerance, this set screw ensures rapid installation and reliable seating in industrial applications where space constraints and vibration are primary concerns.
Specification Summary & Compliance
This metric set screw features precise M4 x 0.7mm coarse threading with Class 6g thread fit according to DIN 916/ISO 4029 manufacturing standards. The component maintains dimensional accuracy with a 6mm length and 2mm hex drive specification. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material traceability for global industrial applications.
