• Versatile industrial use with a 1-1/8" shoulder length and right-hand thread, suitable for pivots, spacers, and guides in machinery.

Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to solve critical alignment and positioning challenges in industrial assemblies. The 18-8 stainless steel material offers excellent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, or outdoor conditions. The precise shoulder with minimal tolerances ensures accurate component spacing and rotational alignment, reducing wear and improving machine reliability. The low-profile socket head and fine UNF thread provide secure fastening in compact designs, commonly used in pivoting mechanisms, guides, and as axles in electronics, automotive, and automation equipment. Its high tensile strength and hardness further support durable performance under dynamic loads, minimizing maintenance needs.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit for consistent engagement and features a 10-32 UNF fine thread with a 1/4" length. The shoulder diameter is 1/4" with a tolerance of -0.001" to 0", and the shoulder length is 1-1/8" with a tolerance of 0" to 0.002" for precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for industrial use.
