Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life
- Precise alignment and smooth rotation ensured by the standard shoulder fit and controlled diameter/length tolerances
- High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for demanding applications
- Reliable, vibration-resistant fastening from the 10-24 UNC coarse thread with a tight Class 3A fit
- Secure, non-slip installation facilitated by the knurled socket head and 1/8" hex drive
- Guaranteed dimensional consistency and interchangeability through compliance with the ASME B18.3 standard
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision assembly and machinery. The UNC coarse thread with Class 3A fit provides excellent engagement and resistance to loosening under vibration, a common failure point in dynamic equipment. The unthreaded shoulder acts as a precise pivot, bearing surface, or locator for gears, linkages, and rotating components, eliminating the need for separate spacers or bushings and simplifying assembly. The combination of high tensile strength and exceptional corrosion resistance makes it a robust fastening solution for industrial applications like food processing, chemical handling, and marine equipment, where durability and material integrity are non-negotiable.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC coarse thread with a precision Class 3A thread fit. The shoulder diameter is held to a tight tolerance of -0.004" to -0.002", and the shoulder length to -0.005" to 0.005". Manufacturing and dimensional specifications conform to the ASME B18.3 standard. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
