Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered from alloy steel to address common industrial challenges like misalignment and component wear. The Black Oxide finish provides a protective layer against rust and corrosion, making it ideal for machinery, automotive, and aerospace applications where exposure to moisture or chemicals is a concern. With a Class 3A thread fit and fine thread spacing, it ensures tight tolerances and minimizes loosening under vibration, enhancing assembly reliability. The knurled head and hex drive facilitate quick adjustments in confined spaces, reducing downtime. Its high tensile strength and hardness make it suitable for heavy-duty uses, offering long-term durability and cost savings by lowering failure rates.
Specification Summary & Compliance
This shoulder screw adheres to UNF thread standards with a Class 3A fit for precise dimensional accuracy, including thread diameter of 0.19" and fine spacing. Shoulder dimensions feature a diameter of 1/4" with tolerance of -0.004" to -0.002" and length of 13/16" with tolerance of -0.005" to 0.005", ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) compliance with exemption 6(a) for lead in steel and REACH (EC 1907/2006) standards, confirming its suitability for regulated industrial applications.
