- Versatile right-hand threading for standard assembly processes across various machinery and equipment
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 3/4" shoulder length with minimal tolerances provides a stable bearing surface, preventing component misalignment and reducing wear in rotating mechanisms. Manufactured from 18-8 stainless steel with a passivated finish, it resists oxidation and chemical exposure, making it suitable for industrial machinery, automotive fixtures, and electronic enclosures. The hex socket drive allows for high-torque installation without stripping, while the Class 2A thread fit ensures consistent clamping force. These features collectively enhance equipment lifespan and reduce maintenance cycles in high-stress environments.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for precise engagement. The shoulder diameter and length maintain tight tolerances (e.g., shoulder length: 0" to +0.002") to ensure accurate positioning. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The combination of material properties and dimensional accuracy supports its use in regulated and precision-driven industries.
