S-98637A283 8-32 x 3/16" MS51963-34 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance through cadmium plating, extending service life in harsh industrial environments
• Exceptional thread engagement with Class 3A fit ensuring precise, vibration-resistant fastening in critical applications
• High-strength performance from Rockwell C45 hardened alloy steel, preventing deformation under heavy loads
• Secure anti-rotation locking with cup point design that bites into mating surfaces for permanent positioning
• Space-saving headless configuration allowing flush mounting where protruding fasteners aren't feasible
• Easy installation and removal with standardized 5/64" hex drive compatible with common industrial tools
• Reliable coarse threading (UNC) that resists cross-threading and speeds assembly in production environments

Professional Applications & Engineering Value

This 8-32 UNC set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The cadmium-plated alloy steel construction provides essential corrosion protection for machinery components exposed to industrial atmospheres, while the Rockwell C45 hardness ensures the cup point maintains its biting capability through repeated stress cycles. The headless design proves invaluable in confined spaces of motor assemblies, gear systems, and precision equipment where traditional fasteners would interfere. With its Class 3A thread fit, this set screw eliminates play in collars, pulleys, and knobs, preventing costly downtime in manufacturing and automation applications where component slippage cannot be tolerated.

Specification Summary & Compliance

This precision fastener features 8-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufactured to MS51963-34 specifications, the screw maintains strict compliance with industrial standards for dimensional consistency and performance reliability. The 3/16" length and 0.164" thread diameter provide optimal sizing for common industrial applications, while the right-hand thread direction follows conventional installation practices. The component meets relevant industry regulations for heavy-duty fastening applications where precision and reliability are non-negotiable.
