Professional Applications & Engineering Value
This 1-64 UNC shoulder screw is engineered to address critical challenges in industrial settings, such as misalignment and corrosion-induced failure. The 316 stainless steel material, combined with a black oxide finish, provides exceptional resistance to chemicals and moisture, extending service life in demanding applications like automotive assemblies, precision instruments, and marine equipment. The coarse UNC thread and Class 3A fit enable quick, secure fastening with minimal risk of stripping, while the knurled head texture and hex socket drive facilitate easy handling in tight spaces. By ensuring consistent performance under high stress, this screw reduces maintenance downtime and enhances operational reliability in industrial shoulder screw applications.
Specification Summary & Compliance
This shoulder screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC coarse threading. Manufacturing specifications cover a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005", ensuring uniformity in assembly. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated industries without hazardous substances.
