- Easy installation and removal using a 3/32" hex drive, providing secure tool engagement without a protruding head
- Secure component positioning with a cup tip design that bites into surfaces to prevent slippage and movement
- Broad compatibility with UNC coarse threads, making it ideal for standard industrial assemblies requiring right-hand threading
- Regulatory peace of mind as it meets ASME B18.3 standards and is RoHS 3 & REACH compliant for safe, global use
Professional Applications & Engineering Value
This 10-24 UNC set screw is engineered to address critical challenges in machinery and equipment assembly, where precise component alignment and resistance to loosening are paramount. The black-oxide alloy steel construction combats rust and wear, ideal for environments exposed to moisture or chemicals. Its headless hex drive and cup tip design allow for flush mounting and strong grip on shafts or collars, preventing rotational slip in high-torque applications like motor pulleys, gears, and precision tools. With a coarse thread and Class 3A fit, it ensures quick installation and tight tolerances, reducing assembly time while enhancing reliability in automotive, aerospace, and industrial manufacturing sectors.
Specification Summary & Compliance
This set screw features a 10-24 UNC thread size with a Class 3A thread fit for high precision and minimal clearance. It adheres to ASME B18.3 manufacturing specifications, ensuring consistent quality and performance. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use worldwide.
