Professional Applications & Engineering Value
This precision shoulder screw delivers critical engineering solutions where component alignment and vibration resistance are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for demanding environments including manufacturing equipment, automotive assemblies, and electronic enclosures. The nylon patch thread locker effectively prevents loosening under continuous vibration, eliminating the need for additional locking hardware. The precisely machined 1-1/4" shoulder with tight tolerances ensures accurate pivot points and bearing surfaces in mechanical linkages, while the 8-32 UNC coarse threads with Class 2A fit guarantee reliable installation in various materials. This combination makes it ideal for applications requiring both rotational freedom and secure fastening.
Specification Summary & Compliance
The shoulder screw features Class 2A thread fit with 8-32 UNC coarse threads and precise shoulder dimensions (3/16" diameter, 1-1/4" length) manufactured to tight tolerances. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
