Professional Applications & Engineering Value

This 8-32 UNC rounded head screw combines 18-8 stainless steel durability with advanced locking technology to solve critical industrial fastening challenges. The internal-tooth lock washer bites into mating surfaces to prevent loosening under vibration, making it ideal for machinery, automotive assemblies, and electrical enclosures where movement-induced failure is a concern. The passivated finish enhances corrosion resistance in humid or chemical environments, while the Phillips pan head design allows for flush mounting and efficient installation. With coarse threading ensuring rapid assembly and full threading maximizing contact area, this fastener delivers reliable performance in vibration-prone applications where maintenance access is limited.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse threads ensuring consistent performance. The screw meets ASME B18.13 specifications for quality and dimensional accuracy. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use in regulated industries. The combination of 18-8 stainless steel and 410 stainless steel lock washer, both with passivated finish, provides corrosion resistance while maintaining the mechanical integrity required for industrial applications.
