Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel and passivated finish, ideal for harsh industrial environments.
- Enhanced durability and strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable, long-lasting performance.
- Precise alignment and reduced wear due to the exact 3/16" shoulder diameter and 9/16" shoulder length, ensuring stable component positioning.
- Easy installation in tight spaces with the low-profile socket head and 3/32" hex drive, allowing efficient assembly with standard tools.
- Consistent thread engagement from the UNC coarse thread and Class 2A fit, minimizing the risk of cross-threading and improving fastener integrity.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
- Right-hand thread design for standard application compatibility and straightforward installation processes.
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and component slippage. The low-profile socket head design, combined with a passivated finish on 18-8 Stainless Steel, provides excellent corrosion resistance in demanding settings like machinery, automotive, and electronics. The precise shoulder diameter and length act as a reliable pivot or spacer, reducing vibration and wear in rotating parts. With a Class 2A thread fit and coarse threading, it ensures quick, secure fastening in high-stress applications, enhancing overall equipment reliability and reducing maintenance needs.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit with UNC coarse threads for consistent dimensional accuracy. It adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it meets strict environmental and safety regulations. Manufacturing specifications include a shoulder diameter of 3/16" with tight tolerance and a shoulder length of 9/16" for precise engineering applications.
