• High load-bearing capacity with 40,000 psi tensile strength and 22,000 psi minimum shear strength for demanding applications.
• Reliable thread engagement provided by UNC coarse threads with Class 2A fit, ensuring easy assembly and vibration resistance.
• Secure and flush installation enabled by the hex socket head, allowing high torque application in confined spaces.
• Consistent mechanical performance from Rockwell B55 hardness, offering excellent durability and deformation resistance.
• Compliance with global regulations including RoHS 3 and REACH, ensuring safety and environmental standards are met.

Professional Applications & Engineering Value

This 3/8"-16 UNC shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 360 Brass construction provides inherent corrosion resistance, making it suitable for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The precise shoulder diameter and length with minimal tolerances ensure accurate component positioning, reducing wear and misalignment in pivots, guides, and rotating parts. The hex socket head allows for secure, high-torque fastening in tight spaces, while the coarse UNC threads with Class 2A fit facilitate quick assembly and maintain integrity under vibration. This screw delivers reliable performance, minimizing maintenance and downtime in heavy-duty shoulder screw applications.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Dimensions include a 1/2" shoulder diameter (-0.002" to 0" tolerance) and 1/2" shoulder length (0" to 0.003" tolerance), ensuring precision. It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006), meeting environmental and safety requirements for industrial use.
