Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw delivers critical engineering solutions where precision alignment and corrosion resistance are paramount. The Class 3A thread fit and UNC coarse threads provide superior vibration resistance in machinery, automation systems, and rotating assemblies. The 1 3/4" shoulder length with tight manufacturing tolerances ensures exact component spacing in jigs, fixtures, and bearing mounts. The passivated finish enhances surface durability while the knurled socket head allows for secure tool engagement in confined spaces. Engineered to withstand 70,000 psi tensile loads, this shoulder screw maintains dimensional stability in high-stress industrial applications while meeting stringent ASME B18.3 specifications.
Specification Summary & Compliance
Manufactured to ASME B18.3 standards with Class 3A thread fit precision and UNC 10-24 coarse threading. Shoulder dimensions maintained within tight tolerances: diameter ±0.001" and length ±0.005". Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Material certification confirms 18-8 stainless steel composition with passivated surface treatment for enhanced corrosion protection.
