Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
- High-strength performance offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing in demanding assemblies.
- Precise thread engagement with Class 3A UNC coarse threads ensuring secure, vibration-resistant fastening and easy installation.
- Enhanced grip and torque application from the knurled hex socket head, reducing tool slippage during high-torque assembly.
- Accurate component alignment provided by the 3/8" shoulder with tight diameter and length tolerances for stable positioning.
- Durable mechanical properties with Rockwell B79 hardness, maintaining integrity under repeated use and stress.
- Compliance with global regulations including RoHS 3 and REACH, ensuring safe use in regulated industries and international markets.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and corrosive environments. The UNC coarse thread and Class 3A fit provide excellent resistance to loosening under vibration, while the knurled hex socket head ensures reliable torque transmission without stripping. The precisely machined shoulder (5/32" diameter, 3/8" length) acts as a pivot or spacer, maintaining alignment in assemblies like rotating shafts, linkages, and bearing mounts. Its high tensile strength and corrosion resistance make it suitable for chemical processing, marine equipment, and food machinery, reducing maintenance and replacement costs.
Specification Summary & Compliance
The screw features a 6-32 UNC thread with Class 3A fit, ensuring tight tolerances for secure fastening. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for precise alignment. Manufactured to high standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting use in environmentally sensitive and industrial applications.
