- Reliable thread engagement with Class 2A fit and 10-32 UNF fine thread, ensuring secure fastening and vibration resistance.
- Space-saving low-profile socket head allows for installation in confined areas while providing a clean, smooth finish.
- Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe and sustainable use.
- Right-hand thread direction for standard installation and ease of use in common assembly applications.
Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered to address critical alignment and wear issues in industrial applications. The precision shoulder fit with minimal diameter and length tolerances ensures exact positioning of moving parts, reducing misalignment and premature failure in machinery, automation systems, and precision instruments. Made from 18-8 stainless steel, it offers excellent corrosion resistance, making it suitable for environments exposed to moisture or chemicals. The low profile socket head design allows for compact assemblies without sacrificing strength, while the fine UNF threads provide superior holding power in dynamic loads. Ideal for use in pivots, gears, and linkages where reliability and repeatability are paramount.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit for consistent engagement, with a shoulder diameter of 1/4" and length of 3/16" held to precise tolerances. It adheres to UNF thread standards and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for global industrial use.
