Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
- Enhanced durability and reduced galling thanks to the Black Oxide finish, providing improved wear resistance.
- Superior torque transmission and slip resistance from the knurled socket head and 3/32" hex drive for reliable fastening.
- High-strength performance with a tensile strength of 70000 psi and minimum shear strength of 35000 psi for demanding applications.
- Precise alignment and spacing ensured by the 5/8" shoulder length, maintaining component position under load.
- Reliable, secure thread engagement with Class 3A UNC coarse threads, offering a tighter fit for vibration resistance.
- Compliance with global environmental standards, being RoHS 3 and REACH compliant for safe and responsible use.
Professional Applications & Engineering Value
This 8-32 UNC Thread Shoulder Screw is engineered to solve critical alignment and load-bearing challenges in industrial machinery, automation systems, and precision assemblies. The 18-8 Stainless Steel material provides excellent resistance to corrosion and oxidation, while the Black Oxide finish reduces friction and prevents seizing in high-stress environments. The 5/8" shoulder length acts as a precise pivot or spacer, ensuring components like gears, pulleys, and linkages maintain accurate positioning without misalignment. With a Class 3A thread fit and coarse thread spacing, it delivers robust performance in applications subject to vibration and dynamic loads, reducing maintenance needs and enhancing operational reliability.
Specification Summary & Compliance
This shoulder screw features precision dimensions, including a shoulder diameter of 3/16" (tolerance: -0.004" to -0.002") and shoulder length of 5/8" (tolerance: -0.005" to 0.005"), with UNC Class 3A threads for high accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material responsibility in industrial use.
