Professional Applications & Engineering Value
This M4 set screw with nylon patch locking addresses critical vibration-induced loosening in industrial assemblies. The 18-8 stainless steel composition provides inherent corrosion resistance, eliminating degradation in demanding environments while maintaining Rockwell B80 hardness for durability. The hex drive headless design enables installation in space-constrained applications where protruding fasteners are impractical. With coarse thread pitch and Class 6g thread fit, this metric set screw ensures rapid assembly and reliable seating in machinery, automotive components, and precision equipment. The cup tip enhances grip on shafts and rotating elements, making it ideal for permanent positioning applications requiring vibration resistance without compromising disassembly capability.
Specification Summary & Compliance
This M4 x 0.7mm x 5mm set screw features Class 6g thread tolerance with coarse thread spacing and right-hand thread direction. Manufactured to DIN 916/ISO 4029 specifications, it includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The nylon patch thread locker maintains effectiveness across the specified temperature range of -50° to 250°F.
