S-90337A313 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments.
• Precise alignment and secure positioning with a shoulder diameter tolerance of -0.001" to 0" and precise shoulder fit, minimizing assembly play.
• High-strength performance with 70,000 psi tensile strength and Rockwell B55 hardness, suitable for heavy-duty applications.
• Easy installation and removal featuring a low-profile hex socket head and 3/32" drive size for efficient tool access in confined spaces.
• Reliable thread engagement due to Class 2A thread fit and coarse UNC threading, providing consistent fastening with reduced cross-threading risk.
• Environmental compliance assurance by meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
• Optimized for automated assembly with right-hand thread direction and smooth head texture, enabling smooth feeding and consistent performance.

Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in industrial settings like machinery, automotive components, and electronic enclosures. The precise shoulder diameter and length tolerances ensure accurate part positioning, reducing wear and misalignment in rotating or sliding mechanisms. Its low socket head profile and hex drive allow for secure tightening in limited-clearance applications, while the Class 2A thread fit and coarse thread spacing enhance installation speed and reliability. Ideal for use in jigs, pivots, and bearing mounts, this shoulder screw combines strength with exacting dimensional control to minimize downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Key dimensional tolerances include a shoulder diameter of 5/32" (tolerance: -0.001" to 0") and shoulder length of 7/16" (tolerance: 0" to 0.002"), ensuring precision in assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
