Professional Applications & Engineering Value
This shoulder screw is engineered to address common industrial challenges, such as misalignment and component wear in machinery. The 18-8 stainless steel material, combined with a black oxide finish, provides excellent resistance to corrosion and oxidation, making it suitable for automotive, aerospace, and manufacturing settings. The UNC coarse thread and 3/8" shoulder length allow for precise positioning in assemblies, reducing vibration and extending equipment life. Its hex drive socket head ensures quick, secure fastening, while the knurled texture enhances grip during installation. Ideal for pivots, spacers, and rotating parts, this screw delivers reliable performance in high-stress environments, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit with precise tolerances for shoulder diameter (-0.004" to -0.002") and length (-0.005" to 0.005"), ensuring consistent dimensional accuracy. It adheres to UNC thread standards and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible and safe industrial use.
