- High-strength alloy steel construction with Rockwell C45 hardness maintains structural integrity under heavy loads
- Secure cup point design provides excellent bite and resistance to vibration-induced loosening
- Compact headless profile enables installation in space-constrained applications where clearance is limited
- Standardized UNC coarse threading allows for quick assembly and compatibility with common industrial components
- Military specification compliance (MS51963-39) guarantees consistent quality and reliability for demanding applications
Professional Applications & Engineering Value
This 8-32 UNC set screw delivers exceptional engineering value in applications requiring reliable, vibration-resistant fastening. The cadmium-plated alloy steel construction provides superior corrosion protection while maintaining Rockwell C45 hardness for lasting performance. The cup point tip creates positive seating and prevents rotational slippage in pulleys, gears, and collars. As a headless set screw with 5/64" hex drive, it offers flush mounting in precision machinery, automotive components, and aerospace assemblies where protrusion isn't acceptable. The Class 3A thread fit ensures precise engagement with mating parts, reducing the risk of cross-threading while providing consistent clamping force in high-vibration environments.
Specification Summary & Compliance
This precision fastener features 8-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. The 1/2" length and 5/64" hex drive provide standardized installation compatibility. Manufactured to meet MS51963-39 specifications, this right-hand threaded set screw maintains strict quality control standards. The cadmium plating offers environmental protection while the alloy steel base material ensures mechanical strength and durability in demanding industrial applications.
