S-97345A115 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for chemical, marine, and outdoor applications.
• Exceptional mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, ensuring reliable performance under high stress and load.
• Precise alignment and positioning enabled by the 3/4" shoulder with controlled diameter and length tolerances for consistent assembly.
• High thread reliability with Class 3A fit for tight, secure fastening and reduced risk of loosening in vibration-prone settings.
• Easy installation and removal using a standard 3/32" hex drive and knurled head for improved grip and torque application.
• Broad industrial compliance with RoHS 3 and REACH regulations, ensuring environmental safety and material suitability for global markets.
• Durable wear resistance from Rockwell B79 hardness, maintaining thread integrity and shoulder surface over repeated use.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical alignment and corrosion challenges in industrial assemblies. The UNC coarse thread with Class 3A fit ensures rapid, secure fastening while minimizing cross-threading risks, which is vital in automated production lines. The 3/4" shoulder length provides a stable pivot or spacer in machinery, reducing misalignment in rotating parts like bearings, pulleys, and linkages. Made from 316 stainless steel, it resists pitting and oxidation in wet or chemical-laden settings, extending service life in applications such as food processing equipment, marine hardware, and pharmaceutical machinery. The hex socket drive and knurled head facilitate quick tool engagement and manual adjustments, streamlining maintenance and reducing downtime.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a 6-32 thread size and Class 3A thread fit for high precision. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", ensuring consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of restricted hazardous substances and suitable for regulated industrial and consumer applications.
