Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Precision Class 3A thread fit provides superior engagement and vibration resistance, minimizing loosening in dynamic environments.
- Black oxide finish offers enhanced corrosion resistance and a durable, non-reflective surface for extended service life.
- Knurled socket head with hex drive allows for secure tool grip and easy installation in confined spaces, improving assembly efficiency.
- Rockwell C32 hardness delivers excellent wear resistance, maintaining dimensional stability under repeated use.
- Fine thread spacing (UNF) ensures tighter sealing and better load distribution compared to coarse threads.
- Compliance with RoHS 3 and REACH guarantees environmental safety and regulatory adherence for global industrial use.
Professional Applications & Engineering Value
This 10-32 UNF alloy steel shoulder screw is engineered to address critical challenges in precision machinery and heavy-duty assemblies. The 1-1/4" shoulder length with tight tolerances provides accurate alignment and spacing in rotating components, such as gears and pulleys, reducing misalignment and wear. The Class 3A thread fit and fine thread spacing enhance vibration resistance in automotive, aerospace, and industrial equipment, preventing unintended disassembly. Combined with the black oxide finish, it offers reliable corrosion protection in harsh environments, while the knurled socket head ensures quick, secure installation with standard hex tools, streamlining maintenance and reducing downtime.
Specification Summary & Compliance
This shoulder screw adheres to UNF thread standards with a Class 3A thread fit for precise engagement. Dimensions include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1-1/4" (tolerance: -0.005" to 0.005"), ensuring consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting safe and sustainable industrial use.
