Professional Applications & Engineering Value
These 316 stainless steel socket head cap screws deliver exceptional performance in corrosive and high-stress environments where ordinary fasteners fail. The combination of Class 3A thread fit and UNC coarse threads ensures reliable engagement in soft materials and vibration-prone applications, while the passivated finish enhances corrosion resistance beyond standard stainless steel. Engineers specify these partially threaded fasteners for precision machinery, marine equipment, chemical processing systems, and food processing applications where 70,000 psi tensile strength and chemical resistance are critical. The hex socket drive provides flush installation in confined spaces, making them ideal for modern compact designs requiring both structural integrity and corrosion protection.
Specification Summary & Compliance
This 1/4"-20 UNC thread socket head cap screw features Class 3A thread fit precision, 1-5/8" length with partial threading, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards. Manufactured to inch system specifications with coarse thread spacing and Rockwell B70 hardness, these industrial fasteners ensure consistent performance in demanding applications requiring exact dimensional accuracy and environmental regulation adherence.
