S-91829A527 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and passivated finish, ideal for harsh industrial environments.
• Precise alignment and reduced assembly wear due to the smooth, precisely toleranced shoulder with minimal diameter and length variation.
• High-strength performance with a tensile strength of 70,000 psi and Rockwell B55 hardness for reliable load-bearing applications.
• Secure and efficient drive using the socket head design, providing high torque transfer and a clean, low-profile appearance.
• Wide compatibility and easy installation with the standard 6-32 UNC coarse thread and Class 2A fit for common industrial components.
• Environmental regulation compliance, meeting RoHS 3 and REACH standards for safe use in regulated markets.
• Durable thread engagement with a right-hand, coarse thread design that resists loosening under vibration.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 18-8 stainless steel construction, enhanced by a passivated finish, provides excellent resistance to corrosion and oxidation, extending service life in demanding conditions. The 3/8" precision shoulder ensures accurate component positioning, minimizing misalignment and wear in assemblies such as rotating machinery, jigs, and fixtures. With its UNC coarse threading and Class 2A thread fit, it offers reliable fastening that withstands vibrational stresses, while the socket head allows for high-torque installation in confined spaces. This combination of material strength and dimensional accuracy delivers consistent performance for OEMs and maintenance teams requiring dependable shoulder screw solutions.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent interchangeability. The shoulder features precise tolerances (diameter: -0.001" to 0", length: 0" to 0.002") to ensure accurate alignment. Manufactured from 18-8 stainless steel with a passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances for industrial and international use.
