S-92012A531 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Precision shoulder dimensions with a 1/4" diameter and 1/8" length (within tight tolerances) provide accurate alignment and smooth rotation for components like bearings and gears.
• Alloy steel construction with Rockwell C32 hardness offers superior durability and wear resistance, extending service life in repetitive-motion machinery.
• Black oxide finish enhances corrosion resistance, protecting the screw from rust in humid or industrial environments without compromising dimensional accuracy.
• Class 2A thread fit with 10-32 UNF fine threads delivers secure, vibration-resistant fastening, ideal for applications where loosening could lead to equipment malfunction.
• Hex socket drive design allows for easy installation and removal with standard tools, minimizing assembly time and improving maintenance efficiency.
• Compliance with RoHS 3 and REACH standards ensures environmental safety and regulatory acceptance for global supply chains.

Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to address common industrial challenges, such as misalignment and wear in rotating assemblies. The alloy steel material, combined with a Rockwell C32 hardness, provides excellent resistance to shear forces and abrasion, making it ideal for machinery like conveyor systems, automotive fixtures, and precision instruments. The black oxide finish not only adds a layer of corrosion protection but also reduces galling during installation. With its fine thread and right-hand thread direction, it ensures tight clamping in applications requiring minimal play, such as in electronic enclosures or robotic arms. The precise shoulder diameter and length allow for consistent positioning of moving parts, reducing downtime and maintenance costs in B2B settings.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit tolerances for consistent engagement, with a shoulder diameter of 1/4" (tolerance: -0.001" to 0") and shoulder length of 1/8" (tolerance: 0" to 0.002"). It meets UNF thread standards for fine threading and is manufactured to ensure reliable performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable industrial use.
