Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws deliver critical corrosion resistance where exposure to chemicals, moisture, or extreme temperatures would compromise ordinary fasteners. The Class 3A thread fit provides superior dimensional accuracy that prevents loosening under vibration while maintaining consistent clamping force. The partially threaded design offers dual functionality - secure threaded engagement combined with unthreaded shank sections for precise alignment in machinery, automotive assemblies, and marine equipment. The coarse UNC threading enables rapid installation in production environments while the passivated finish enhances surface durability. These industrial fasteners are specifically engineered to withstand high-stress applications where reliability and longevity are paramount.

Specification Summary & Compliance

This socket head cap screw features 3/8"-16 UNC coarse threads with Class 3A precision thread fit meeting standardized inch system requirements. The fastener maintains a minimum thread length of 1-1/4" on its 3-1/2" overall length with standard socket head profile. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications with strict compliance requirements. The right-hand thread direction and hex drive configuration adhere to industry-standard installation practices.
