Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel and passivated finish, ideal for harsh industrial environments.
- Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B55 hardness for reliable, long-lasting performance.
- Precise alignment and positioning ensured by the 3/16" shoulder diameter with tight tolerance (-0.001" to 0") for minimal play in assemblies.
- Easy installation and removal using a standard 3/32" hex drive, reducing assembly time and tool wear.
- Consistent thread engagement with UNC coarse threads and Class 2A fit, providing secure fastening in various materials.
- Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe, sustainable use.
- Smooth, low-profile socket head for a clean finish and reduced risk of snagging in compact spaces.
Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, automation systems, and electronic enclosures. The 18-8 stainless steel construction, enhanced by a passivated finish, resists oxidation and chemical exposure, extending service life in demanding conditions. The 3/16" shoulder diameter with precise tolerances acts as a reliable pivot or spacer, minimizing misalignment and vibration in assemblies. With a hex drive design, it allows for high-torque installation without stripping, while the Class 2A thread fit ensures consistent performance in industrial applications requiring repeatable disassembly and reassembly.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for reliable engagement. Dimensions include a shoulder diameter of 3/16" (tolerance: -0.001" to 0") and shoulder length of 1/16" (tolerance: 0" to 0.002"), ensuring precise manufacturing. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible sourcing and usage in global markets.
