S-92432A462 5/16"-18 x 3/4" Set Screws

Key Features & Benefits at a Glance

• Enhanced Grip & Alignment: Permanent swivel tip with 7.5° maximum angle ensures superior contact and compensates for minor surface irregularities, providing a more secure and reliable hold.
• Exceptional Durability & Strength: Made from alloy steel with a Rockwell C45 hardness, this set screw offers high resistance to wear and deformation under heavy loads.
• Superior Corrosion Resistance: The black-oxide coating provides a protective layer, significantly extending the component's service life in demanding industrial environments.
li>Precise & Reliable Threading: Class 2A thread fit for the 5/16"-18 UNC coarse thread ensures easy assembly and a consistent, secure fit with standard mating parts.
• Optimized for High-Torque Applications: The headless design with a 5/32" hex drive allows for flush installation and enables high tightening torque in confined spaces.
• Regulatory Compliance for Global Markets: Meets RoHS 3 and REACH standards, ensuring the fastener is suitable for use in regulated industries and international supply chains.
• Simplified Installation: The right-hand thread direction and coarse thread spacing facilitate quick and straightforward installation, reducing assembly time.

Professional Applications & Engineering Value

This 5/16"-18 UNC set screw is engineered to solve critical challenges in power transmission and motion control systems. Its permanent swivel tip is a key feature, preventing fretting and damage to shafts and collars by distributing clamping force evenly, even on slightly uneven surfaces. The black-oxide alloy steel construction provides the necessary Rockwell C45 hardness to resist loosening under vibration, a common failure point in machinery. The headless, hex drive design is ideal for applications where space is limited and a flush finish is required, such as in securing gears, pulleys, and knobs onto rotating shafts. This combination of a secure tip, robust material, and compact form factor delivers reliable, long-term performance in demanding industrial applications.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, featuring a Class 2A thread fit for the UNC coarse thread (5/16"-18), ensuring interchangeability and reliable performance. The manufacturing and material composition are confirmed to be RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety regulations for industrial components.
