Key Features & Benefits at a Glance
- Exceptional durability with 140,000 psi tensile strength and Rockwell C30 hardness for reliable performance in high-stress industrial environments.
- Enhanced corrosion resistance from the black oxide finish, extending service life in harsh conditions.
- Precise alignment and reduced wear due to the Class 3A thread fit and standard shoulder fit, ensuring smooth assembly and long-term reliability.
- Secure, low-profile installation with the knurled, low socket head and 1/8" hex drive, preventing slippage in confined spaces.
- Versatile coarse UNC threading (10-24) for quick engagement and robust holding power in various materials.
- Consistent dimensional accuracy with tight shoulder diameter and length tolerances, facilitating exact positioning in machinery and fixtures.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical needs in precision assemblies, such as pivot points, rotating shafts, and locating pins in machinery, automotive, and automation systems. The black oxide finish provides a protective layer against rust and wear, while the Class 3A thread fit and coarse UNC thread ensure secure fastening with minimal risk of cross-threading. The knurled, low-profile socket head allows for easy installation with standard hex tools, even in tight spaces, reducing assembly time and improving maintenance efficiency. With a 3/8" shoulder length and precise tolerances, it offers reliable alignment and load distribution, preventing misalignment and extending the life of connected components in demanding applications.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Dimensions include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1/2" (tolerance: -0.005" to 0.005"), ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting use in environmentally conscious industrial settings.
