Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel and passivated finish for long-lasting performance in harsh environments.
- Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing applications.
- Precise component alignment enabled by the precisely fitted shoulder with minimal diameter tolerance (-0.001" to 0") and length tolerance (0" to 0.002").
- Easy installation and removal using the standard hex socket drive (3/32") for secure, slip-resistant torque application.
- Wide compatibility with 8-32 UNC coarse threading and Class 2A thread fit, ensuring consistent engagement in various assemblies.
- Regulatory compliance meeting RoHS 3 and REACH standards for safe use in global industrial markets.
- Optimized design combining a 1-3/4" shoulder length for stable pivoting and a 3/16" thread length for secure fastening.
Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in precision machinery. The passivated finish enhances corrosion resistance, making it ideal for environments exposed to moisture or chemicals. Its UNC coarse threading and Class 2A thread fit provide reliable fastening with reduced cross-threading risks, while the precisely machined shoulder ensures minimal play in rotating assemblies like pivots, gears, and linkages. With a 70,000 psi tensile strength, it supports high-stress applications in automotive, aerospace, and industrial equipment, offering long-term reliability and reduced maintenance needs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder features precise tolerances: diameter (-0.001" to 0") and length (0" to 0.002"). It is manufactured from 18-8 Stainless Steel with a passivated finish and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
