Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws with nylon patch thread locker provide critical vibration resistance in machinery, automotive, and aerospace applications where UNC coarse threads and Class 3A precision ensure reliable performance. The combination of 170,000 psi tensile strength and Rockwell C37 hardness addresses common failure points in high-stress assemblies, while the temperature-stable locking patch prevents loosening under thermal cycling. Engineered for industrial fastening solutions, these screws maintain integrity in vibrating equipment, precision instruments, and heavy-duty manufacturing systems where secure connections are non-negotiable.
Specification Summary & Compliance
This 6-32 x 1" socket head cap screw features Class 3A thread fit with UNC coarse threads and right-hand direction, manufactured to ASME B18.3 specifications using ASTM A574 alloy steel. The fastener meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility alongside mechanical excellence in inch-system applications.
