Key Features & Benefits at a Glance
- Secure Component Locking – Class 3A thread fit ensures tight, vibration-resistant fastening for critical assemblies
- Superior Corrosion Resistance – Black-oxide coating on alloy steel provides durable protection in demanding industrial environments
- Precision Tip Protection – Brass soft tip (0.094" diameter) prevents damage to sensitive shaft surfaces while maintaining grip
- Optimized Installation Torque – 3/32" hex drive enables controlled tightening with standard industrial tools
- Enhanced Mechanical Strength – Rockwell C28 hardness delivers reliable performance under repeated stress cycles
- Industry-Standard Compatibility – 10-24 UNC coarse thread design ensures interchangeability with existing equipment
- Space-Saving Design – Headless configuration allows flush mounting in confined assembly spaces
Professional Applications & Engineering Value
This black-oxide alloy steel set screw addresses critical challenges in precision assembly applications where component slippage and surface damage must be prevented. The 10-24 UNC coarse thread with Class 3A fit maintains positional accuracy in vibrating environments, while the brass soft tip eliminates marring on precision shafts and rotating components. Engineered for machinery, automotive, and electronic assemblies, the headless hex drive configuration provides reliable torque transmission without protruding hardware. The combination of Rockwell C28 hardness and controlled thread engagement delivers exceptional resistance to loosening in high-cycle applications, making it ideal for permanent positioning of gears, pulleys, and collars where maintenance access is limited.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for consistent dimensional accuracy. The 10-24 UNC coarse thread maintains standard interchangeability while the 3/16" length provides optimal engagement depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across global industrial markets. The right-hand thread direction and 3/32" hex drive conform to industry-standard installation practices.
