Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional engineering value in applications requiring exact component positioning and reliable fastening. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for manufacturing equipment, electronic assemblies, and automotive components where environmental factors are a concern. The 3/8" shoulder length with precise fit tolerance ensures accurate alignment of moving parts, reducing wear and maintaining operational accuracy. The combination of 70,000 psi tensile strength and Rockwell B55 hardness guarantees long-term performance under mechanical stress, while the low-profile socket head with slotted drive offers installation flexibility in confined spaces. These shoulder screws effectively solve alignment and durability challenges in precision mechanisms, pivot points, and bearing assemblies.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit with UNC coarse threads (2-56 size) and precise shoulder dimensions (3/32" diameter with -0.001" to 0" tolerance, 3/8" length with 0" to 0.002" tolerance). Manufactured from 18-8 stainless steel with right-hand threading and low-profile socket head design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety in industrial applications.
