Professional Applications & Engineering Value
These low profile socket head cap screws in 316 stainless steel address critical engineering challenges in precision equipment, marine hardware, and chemical processing systems where space limitations and corrosive environments compromise fastener performance. The UNC coarse thread configuration with Class 3A fit ensures rapid assembly with minimal galling risk, while the fully threaded design provides consistent clamping force across the entire engagement length. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes these industrial fasteners suitable for high-vibration applications where maintaining preload is essential. The low profile head enables flush mounting in recessed cavities, solving clearance issues in compact machinery designs without sacrificing the torque capacity of the 5/32" hex drive.
Specification Summary & Compliance
Manufactured to precise inch system dimensions including 5/16"-18 UNC thread with Class 3A fit tolerance for superior thread engagement. Features right-hand thread direction with coarse thread spacing and fully threaded shank design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction of hazardous substances for global industrial applications.
