Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel material, ideal for harsh or humid industrial environments.
- High tensile and shear strength (70,000 psi tensile, 35,000 psi min shear) ensures reliable performance under heavy loads.
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies.
- Knurled socket head with hex drive offers excellent grip and easy installation, reducing tool slippage.
- Accurate shoulder dimensions (3/16" diameter, 3/8" length with tight tolerances) enable precise alignment in machinery.
- RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for global supply chains.
- Coarse UNC thread allows for quick assembly and disassembly, improving maintenance efficiency.
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. Made from 18-8 stainless steel, it resists rust and corrosion, making it suitable for applications in automotive, aerospace, and electronic equipment where exposure to moisture or chemicals is common. The Class 3A thread fit and controlled shoulder dimensions ensure minimal play and exact positioning, reducing wear and misalignment in rotating parts or bearing mounts. Its socket head with knurling enhances torque transmission, preventing stripping during high-stress installations. Ideal for use in jigs, fixtures, and pivoting mechanisms, this screw delivers long-term reliability and compliance with industry standards like RoHS and REACH, supporting sustainable manufacturing practices.
Specification Summary & Compliance
The screw features a Class 3A thread fit per UNC standards, with precise tolerances for shoulder diameter (-0.004" to -0.002") and length (-0.005" to 0.005"). It adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. Manufactured to meet high mechanical properties, including a Rockwell B55 hardness and 70,000 psi tensile strength, it is designed for consistent performance in demanding engineering applications.
