Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision instruments. The 18-8 stainless steel construction, combined with a passivated finish, provides excellent resistance to corrosion and wear, reducing maintenance frequency in humid or chemically aggressive settings. The 5/32" shoulder diameter and precise shoulder fit act as a reliable pivot or spacer, ensuring accurate positioning of gears, pulleys, or linkages without the need for additional bushings. With 6-32 UNC coarse threads and a Class 2A thread fit, it offers quick assembly and secure fastening, while the high tensile strength supports heavy-duty rotational and axial loads, making it a versatile solution for OEM and MRO applications.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent, reliable engagement. The shoulder diameter is machined to a tight tolerance of -0.001" to 0", and the shoulder length is held to 0" to 0.002" tolerance, ensuring precise dimensional accuracy. Manufactured from 18-8 stainless steel with a passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and commercial use without hazardous substances.
