Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments
- Exceptional holding power achieved through Rockwell C45 hardness, preventing deformation under high torque loads
- Precise Class 3A thread fit ensures reliable engagement and vibration resistance in critical assemblies
- Secure installation with 3/32" hex drive design, providing positive torque transfer and reducing tool slippage
- Optimal material displacement from cup tip design, creating permanent seating in shafts and collars
- Right-hand coarse UNC threading enables quick installation and removal while maintaining strong fastening integrity
- Headless construction allows for flush mounting in space-constrained applications without protruding components
Professional Applications & Engineering Value
This 10-24 UNC set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and permanent positioning are critical. The black-oxide alloy steel construction provides superior protection against corrosion while maintaining the Rockwell C45 hardness necessary for high-torque applications. The cup tip design creates concentrated pressure points that bite into shaft materials, preventing rotational slippage in pulleys, gears, and collars. The Class 3A thread fit ensures precise engagement with mating components, making these headless set screws ideal for machinery, automotive, and aerospace applications where reliability cannot be compromised. The coarse thread spacing allows for rapid installation while maintaining strong holding characteristics in both soft and hard materials.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread tolerance for precision fit. Features UNC coarse threading with 10-24 size, 0.19" diameter, and 1" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel substrate meets industrial corrosion protection standards while maintaining dimensional stability.
