S-94035A162 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Precise component alignment with a 3/16" diameter shoulder and controlled length tolerance for consistent positioning in assemblies.
• Excellent corrosion resistance provided by 18-8 Stainless Steel material and a passivated finish for long-term reliability in harsh environments.
• High mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness to withstand significant operational loads.
• Secure and reliable fastening ensured by the Class 2A thread fit and coarse UNC thread, which resist loosening under vibration.
• Easy installation and removal with a hex socket drive, allowing for high torque application in confined spaces.
• Compliance with global standards including RoHS 3 and REACH, ensuring environmental safety and material restrictions are met.
• Durable performance from the smooth, standard socket head design that resists wear and deformation during use.

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial assemblies. The 18-8 Stainless Steel construction, combined with a passivated finish, offers superior resistance to corrosion and oxidation, making it ideal for machinery, automotive, and electronic applications exposed to moisture or chemicals. The precisely machined 3/16" shoulder diameter and 9/32" shoulder length provide a stable pivot or spacer, reducing misalignment and wear in moving parts. With a Class 2A thread fit and coarse thread design, it ensures quick assembly and reliable retention under dynamic stresses, while the hex socket head facilitates efficient installation with standard tools, minimizing downtime in production lines.

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"; length: 0" to 0.002") to ensure exact alignment. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. Manufactured from 18-8 Stainless Steel, it meets industry benchmarks for mechanical performance, including a tensile strength of 70,000 psi and Rockwell B55 hardness.
