- Maximum holding power achieved through Class 3A thread fit precision and extended tip design for deeper penetration and secure fastening
- Enhanced durability with Rockwell B80 hardness providing excellent resistance to wear and deformation under load
- Reliable installation using standard 1/8" hex drive tools for secure torque application without stripping
- Optimized for industrial applications with coarse UNC threads enabling quick assembly and vibration resistance
- Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH
- Space-saving headless design allowing flush mounting in applications where protruding fasteners are not feasible
Professional Applications & Engineering Value
This 1/4"-20 UNC Class 3A set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and corrosion protection are critical. The 18-8 stainless steel construction provides reliable performance in moist or chemical environments, while the extended tip design ensures superior grip by penetrating deeper into mating materials. The hex drive configuration allows for high torque application without slippage, making it ideal for machinery, automotive components, and precision equipment where secure fastening is paramount. The headless configuration enables flush mounting in space-constrained assemblies, while the coarse thread pitch facilitates quick installation and removal in maintenance scenarios.
Specification Summary & Compliance
This set screw features precision UNC Class 3A threads with 1/4"-20 sizing and right-hand thread direction. The extended tip maintains tight tolerances with tip diameter of 0.156" (-0.007" to 0 tolerance) and tip length of 0.067" (-0.005" to 0 tolerance). Manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
