- High torque transmission capability with knurled socket head and 5/32" hex drive, preventing tool slippage during installation
- Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications
- Optimized for rapid assembly with coarse UNC threads and right-hand thread direction, reducing installation time
- Consistent dimensional accuracy with tight shoulder diameter and length tolerances, ensuring reliable repeatability in automated systems
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing requirements
Professional Applications & Engineering Value
Engineered for precision motion control and rotational assemblies, these 18-8 stainless steel shoulder screws provide critical pivot points and bearing surfaces in industrial machinery. The Class 3A thread fit ensures minimal backlash in high-vibration environments, while the knurled socket head design prevents cam-out during high-torque installation. The 5/16"-18 UNC coarse threads enable quick assembly in production lines, and the hardened Rockwell B55 material maintains dimensional stability under repeated loading cycles. Ideal for precision equipment, automotive fixtures, and conveyor systems where corrosion-resistant shoulder bolts must maintain exact alignment between moving components.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit per UNC specifications and precise shoulder diameter tolerance of -0.004" to -0.002". Thread dimensions conform to 5/16"-18 UNC coarse thread standards with right-hand orientation. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
