Professional Applications & Engineering Value
This 1/4"-20 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, making it suitable for applications in moist or aggressive environments, including automotive, machinery, and marine equipment. The headless slotted design with a cup point tip ensures a firm grip on shafts and collars, preventing rotational movement and enhancing the longevity of assemblies. Its coarse thread and Class 2A thread fit facilitate quick installation and reliable performance in high-vibration settings, reducing maintenance needs and downtime. Ideal for securing gears, pulleys, and knobs, this set screw delivers consistent holding power and meets rigorous industrial standards for safety and efficiency.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC thread with Class 2A dimensional accuracy, ensuring precise fit and interchangeability. It complies with ASME B18.6.2 specifications for set screws, along with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial applications.
