Professional Applications & Engineering Value
This 3/8"-16 UNC shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial machinery, automation systems, and precision equipment. The 1/2" diameter shoulder provides a stable bearing surface that minimizes component misalignment and distributes shear forces effectively, reducing wear on mating parts. Made from 18-8 stainless steel with a passivated finish, it offers superior resistance to rust and chemicals, ensuring longevity in demanding environments like manufacturing plants or outdoor applications. The hex socket head allows for high-torque installation in confined spaces, while the coarse thread spacing and Class 2A thread fit enable quick assembly and reliable holding power. Ideal for use in pivots, axles, and guides, this fastener enhances operational efficiency and reduces maintenance downtime.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. The shoulder features precise tolerances: diameter of -0.001" to 0" and length of 0" to 0.002". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international industrial use.
