Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable performance in demanding applications.
- Precise alignment and smooth rotation ensured by the 1/2" diameter shoulder with standard fit, reducing wear on mating components.
- Superior corrosion resistance from the zinc plating, extending service life in various industrial environments.
- Easy installation and high torque transmission with the external hex drive and smooth hex head design.
- Wide compatibility and secure fastening thanks to the 3/8"-16 UNC coarse thread with Class 2A fit for consistent engagement.
- Enhanced durability from the steel construction and Rockwell B80 hardness, resisting deformation under stress.
- Compliance with environmental and safety standards, including RoHS 3 and REACH, for use in regulated industries.
Professional Applications & Engineering Value
This shoulder screw is engineered to address critical alignment and pivot point challenges in industrial assemblies. The steel construction and zinc plated finish provide robust corrosion protection, while the precise 1/2" shoulder diameter and 1-7/16" shoulder length allow for accurate component positioning, reducing misalignment and wear in machinery, automotive, and conveyor systems. The 3/8"-16 UNC right-hand thread with Class 2A fit ensures quick, secure fastening, making it ideal for applications requiring repeated disassembly. Its high tensile strength supports heavy-duty use, minimizing failure risks and maintenance costs in precision engineering projects.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with Class 2A thread fit for consistent tolerance. Shoulder dimensions include a diameter of 1/2" (tolerance: -0.004" to 0") and length of 1-7/16" (tolerance: -0.005" to 0.005"), ensuring precise manufacturing. It is RoHS 3 (2015/863/EU) compliant under exemption 6(a) for lead in steel and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for industrial use.
