S-92432A466 5/16"-18 x 1 1/2" Set Screws

Key Features & Benefits at a Glance

• Enhanced Durability - Black-oxide coating on alloy steel provides superior corrosion resistance and extends service life in demanding industrial environments.
• Precision Fastening - Class 2A thread fit ensures consistent, reliable engagement with minimal risk of cross-threading or loosening during operation.
• Maximum Grip Strength - Permanent swivel tip with 7.5° maximum angle distributes pressure evenly, preventing component slippage and maintaining secure positioning.
• High Torque Capability - Hex drive design (5/32") combined with Rockwell C45 hardness allows for high tightening torque without stripping or deformation.
• Simplified Installation - Coarse UNC threads enable quick assembly and disassembly, reducing labor time in maintenance and production cycles.
• Regulatory Compliance - Meets RoHS 3 and REACH environmental standards, ensuring safe use in regulated industries and global market acceptance.
• Space-Efficient Design - Headless construction with 1-1/2" length provides flush mounting in confined spaces while maintaining full thread engagement.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance in precision machinery, automotive assemblies, and industrial equipment where vibration resistance and positional accuracy are paramount. The permanent swivel tip technology eliminates point loading issues that cause surface damage to shafts and collars, while the Rockwell C45 hardness ensures the fastener maintains its structural integrity under repeated stress cycles. The UNC coarse thread profile provides superior holding power in softer materials and enables rapid installation in high-volume manufacturing environments. Engineers specify this hex drive set screw for applications requiring reliable torque transmission and consistent clamping force without frequent retightening, significantly reducing maintenance intervals and downtime in continuous operation systems.
