Professional Applications & Engineering Value
This 6-32 x 3/8" Phillips pan head screw with spring lock washer addresses critical vibration-induced loosening challenges in industrial equipment, machinery, and electronic enclosures. The combination of 18-8 stainless steel material and passivated finish provides exceptional corrosion resistance in harsh environments, while the spring lock washer maintains permanent tension to prevent back-off under continuous vibration. The fully threaded UNC coarse thread design ensures rapid installation and superior pull-out resistance, making it ideal for assembly lines requiring both speed and reliability. With 70,000 psi tensile strength and Rockwell B80 hardness, this fastener delivers consistent performance in high-stress applications where material integrity is paramount.
Specification Summary & Compliance
This rounded head screw features precise Class 2A thread fit with UNC 6-32 coarse threads and right-hand threading. Manufacturing complies with ASME B18.13 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The spring lock washer, manufactured from 410 stainless steel with passivated finish, provides complementary corrosion resistance and permanent vibration protection.
