Professional Applications & Engineering Value
This 10-32 UNF alloy steel shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component wear. The Class 3A fine threads and robust alloy steel construction provide superior resistance to loosening under vibration, making it ideal for high-stress applications in automotive, aerospace, and industrial equipment. The Black Oxide finish not only enhances corrosion resistance but also reduces friction during assembly. With a knurled socket head and precise shoulder dimensions, it ensures accurate positioning and ease of maintenance in assemblies requiring repeated disassembly, thereby reducing downtime and improving operational reliability.
Specification Summary & Compliance
This shoulder screw adheres to UNF thread standards with Class 3A tolerance for precise fit. Key dimensions include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1 3/8" (tolerance: -0.005" to 0.005"). It is manufactured from alloy steel and complies with RoHS 3 (2015/863/EU) with exemption 6(a) and REACH (EC 1907/2006) regulations, ensuring environmental safety and quality consistency.
