Key Features & Benefits at a Glance
- Exceptional strength and durability with alloy steel construction and 140,000 psi tensile strength, ensuring reliable performance in high-stress applications.
- Superior corrosion resistance provided by the black oxide finish, extending service life in harsh industrial environments.
- Precise alignment and stability due to the smooth shoulder with a tight tolerance of 0.002", minimizing misalignment and vibration.
- Easy installation and removal with a hex socket drive (3/32"), allowing secure tool engagement and reducing assembly time.
- Wide compatibility with UNC coarse threads and Class 2A fit, ensuring consistent engagement with standard components.
- High hardness rating of Rockwell C32, offering excellent wear resistance and maintaining thread integrity over repeated use.
- Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global industrial supply chains.
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and load-bearing challenges in machinery and assemblies. The alloy steel material, combined with a black oxide finish, provides robust resistance to wear and corrosion, ideal for automotive, aerospace, and manufacturing equipment. The precise shoulder fit with minimal tolerance ensures accurate positioning of moving parts, reducing downtime from misalignment. With a coarse thread and right-hand direction, it facilitates quick assembly in high-vibration environments, while the socket head design allows for compact installations where space is limited. These features make it a reliable choice for pivots, axles, and guides in demanding industrial applications.
Specification Summary & Compliance
The screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement, and shoulder dimensions include a diameter of 3/16" and length of 5/8" with tight tolerances (e.g., shoulder length tolerance of 0" to 0.002"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for various industrial sectors.
