S-93985A528 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 416 Stainless Steel construction, ideal for harsh industrial environments and extended service life.
• High mechanical strength and durability from Rockwell C26 hardness and 120,000 psi tensile strength, preventing stripping and failure under load.
• Precise alignment and reduced wear due to the accurately machined shoulder with a 5/32" diameter and 7/16" length for stable component positioning.
• Efficient assembly and disassembly using the 3/32" hex socket drive, allowing high-torque application in confined spaces.
• Reliable thread engagement with Class 2A fit and 6-32 UNC coarse thread, ensuring consistent fastening and vibration resistance.
• Compliance with global environmental standards including RoHS 3 and REACH, making it suitable for regulated industries and export markets.
• Versatile right-hand thread design for standard applications, facilitating easy integration with existing components and tools.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and durability challenges in mechanical assemblies. The 416 Stainless Steel material provides excellent corrosion resistance, essential for equipment exposed to moisture, chemicals, or outdoor conditions. The hex socket head allows for secure, high-torque installation without slippage, while the precise shoulder fit ensures components like gears, pulleys, or bearings are accurately located, reducing misalignment and wear. With a coarse 6-32 UNC thread and Class 2A fit, it offers quick assembly and reliable performance in vibrating environments, making it ideal for machinery, automotive, and electronics applications where strength and precision are paramount.

Specification Summary & Compliance

The screw features a Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter is 5/32" with a tight tolerance of -0.001" to 0", and the shoulder length is 7/16" with a 0" to 0.002" tolerance for precise fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted substances and suitable for industrial and international use.
