Professional Applications & Engineering Value
These 316 stainless steel socket head cap screws deliver critical performance advantages in corrosive and high-stress environments. The passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel, making these fully threaded fasteners ideal for chemical processing equipment, marine hardware, and food-grade applications where moisture and aggressive agents are present. The Class 3A thread fit and UNC coarse threading provide superior vibration resistance and reliable seating in precision machinery, while the hex socket drive allows for high-torque installation in confined spaces. With their 70,000 psi tensile strength, these screws maintain structural integrity under substantial mechanical loads, reducing failure risks in critical assemblies.
Specification Summary & Compliance
This socket head cap screw features 4-40 UNC coarse threads with Class 3A fit for precision tolerance, right-hand thread direction, and standard socket head profile. Manufactured from 316 stainless steel with passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements. The fastener provides consistent dimensional accuracy with specified head diameter (0.183"), head height (0.112"), and 1-1/2" length for reliable interchangeability in industrial applications.
