Professional Applications & Engineering Value
This M2 hex headless set screw delivers critical vibration resistance in precision assemblies where space constraints and reliability are paramount. The nylon patch thread locker eliminates the need for secondary locking compounds while providing permanent fastening security in applications subject to thermal expansion and mechanical stress. Manufactured from 18-8 stainless steel with Rockwell B80 hardness, it maintains structural integrity in corrosive environments while the cup tip design ensures maximum gripping force on shafts and axles. Ideal for precision instruments, robotics, and industrial machinery where metric coarse threads and compact headless profiles are essential for space-optimized designs.
Specification Summary & Compliance
This metric set screw features M2 x 0.4 mm coarse threads with Class 6g tolerance for precision fit, 4 mm length, and hex drive configuration. Manufactured to DIN 916 specifications (equivalent to ISO 4029) with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread direction and standardized dimensions ensure compatibility with industrial fastener systems.
