S-94128A151 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior alignment accuracy with precise shoulder diameter tolerance (-0.001" to 0") ensuring minimal play in assembled components
• Enhanced load-bearing capacity from high-strength alloy steel construction with Rockwell C32 hardness for extended service life
• Reliable thread engagement through Class 3A thread fit providing secure fastening in vibration-prone environments
• Quick installation compatibility with standard slotted drive design for efficient assembly using common tools
• Optimized for coarse-thread applications with 8-32 UNC right-hand thread offering superior resistance to loosening
• Space-saving headless configuration allowing flush mounting in compact mechanical assemblies
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

This alloy steel shoulder screw delivers critical precision in applications requiring exact rotational alignment and axial positioning. The 3/16" shoulder diameter with tight tolerance control (-0.001" to 0") eliminates component wobble in precision machinery, while the 8-32 UNC coarse thread with Class 3A fit maintains clamping force under dynamic loads. The Rockwell C32 hardness provides exceptional wear resistance in high-cycle applications such as robotic arms, conveyor systems, and automated manufacturing equipment. The headless design with slotted drive enables streamlined integration in confined spaces while maintaining service accessibility.

Specification Summary & Compliance

Manufactured to exacting standards with Class 3A thread fit per UNC specifications and precise shoulder diameter tolerance of -0.001" to 0". The shoulder length maintains 1/2" dimension with 0" to 0.005" tolerance for consistent positioning. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety in industrial applications.
