Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Precise alignment and smooth rotation due to the 3/8" diameter shoulder with tight tolerances for consistent performance.
- High mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications.
- Secure and slip-resistant installation enabled by the knurled socket head and hex drive design.
- Reliable thread engagement with a UNC coarse thread and Class 2B fit for easy assembly and vibration resistance.
- Versatile partial threading allowing the unthreaded shoulder to act as a pivot, bearing surface, or spacer.
- Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to solve critical alignment and assembly challenges in precision machinery, automation systems, and electronic enclosures. The 18-8 stainless steel provides excellent resistance to rust and corrosion, extending service life in demanding conditions. The 3/4" shoulder length and 3/8" shoulder diameter with controlled tolerances ensure accurate component positioning, reducing wear and misalignment. The partially threaded design allows the smooth shoulder to serve as a durable bearing surface or pivot point, while the knurled socket head offers a secure grip for efficient installation and maintenance. Ideal for applications requiring repeated adjustments or exposure to moisture, this screw enhances reliability in industrial assembly and precision mechanisms.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2B thread fit for consistent engagement. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", ensuring high dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible sourcing and use in regulated industries.
