Professional Applications & Engineering Value
Engineered for critical industrial fastening applications, these 10-32 UNF flat head screws with nylon patch locking technology provide permanent vibration resistance where conventional fasteners fail. The black-oxide alloy steel construction delivers exceptional corrosion resistance while maintaining 130,000 psi tensile strength for high-stress assemblies. The Class 3A thread fit ensures precise engagement in machinery, automotive, and aerospace applications where vibration loosening compromises safety. With temperature resistance from -65° to 250°F and partial threading design, these screws offer reliable performance in thermal cycling environments while the 82° countersink angle provides flush mounting for streamlined assemblies.
Specification Summary & Compliance
Manufactured to ASTM F835 specifications with Class 3A thread fit and UNF fine threading. Features include 1-1/2" length, 7/8" minimum thread length, and 1/8" hex drive. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The nylon patch thread locker provides permanent locking capability without compromising 130,000 psi tensile strength or Rockwell C39 hardness properties.
