Professional Applications & Engineering Value

These 6-32 UNC thread shoulder screws are engineered to address critical assembly challenges in precision industries such as machinery, electronics, and automation. The 18-8 stainless steel material provides excellent corrosion resistance, reducing maintenance costs in humid or chemical-exposed settings. The hex socket head with a knurled texture allows for secure, high-torque installation without slippage, while the Class 3A thread fit and standard shoulder ensure accurate positioning and smooth rotational movement in pivots, guides, and spacers. This design minimizes wear and misalignment, enhancing the longevity and reliability of your equipment. Ideal for applications requiring consistent tensile and shear strength, these screws deliver dependable performance in demanding B2B environments.

Specification Summary & Compliance

This shoulder screw features a Class 3A thread fit with UNC 6-32 coarse threads and precise shoulder diameter and length tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002"). Manufactured to high standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for industrial use.
