Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure.
- Enhanced assembly grip and reduced tool slippage due to the knurled socket head design and 5/32" hex drive.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength for demanding mechanical applications.
- Precise component alignment and reduced wear ensured by the standard shoulder fit and controlled diameter/length tolerances.
- Reliable thread engagement and vibration resistance from the Class 3A thread fit and coarse UNC thread form.
- Long-term durability and material integrity supported by Rockwell B79 hardness and compliance with ASME B18.3 standards.
- Environmentally compliant and safe for regulated industries, meeting RoHS 3 and REACH requirements.
Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address critical alignment and load-bearing challenges in precision assemblies. The 316 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and food-grade equipment. The knurled socket head enhances torque application, reducing the risk of stripping during installation in high-vibration environments like robotics or conveyor systems. With a Class 3A thread fit and robust 70,000 psi tensile strength, it ensures secure fastening in dynamic loads, while the shoulder provides accurate positioning for rotating parts, bearings, or linkages, minimizing misalignment and extending service life.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for precise UNC threading. Dimensions include a shoulder diameter of 5/16" (tolerance: -0.004" to -0.002") and shoulder length of 1/2" (tolerance: -0.005" to 0.005"), ensuring consistent performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety standards for industrial use.
