Professional Applications & Engineering Value
This 1/4"-20 UNC set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. The cup point design creates concentrated pressure that digs into shaft surfaces, preventing rotational slippage in pulleys, gears, and collars. With Class 2A thread fit and coarse UNC threading, installation is straightforward while maintaining secure fastening in right-hand thread applications. The headless configuration allows flush mounting where protruding fasteners would interfere with moving components, making it ideal for precision equipment, automotive assemblies, and manufacturing machinery requiring reliable set screw performance.
Specification Summary & Compliance
This set screw maintains Class 2A thread tolerance per UNC standards with precise 1/4"-20 coarse threading and 0.25" diameter. Manufacturing complies with ASME B18.6.2 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations regarding hazardous substances, ensuring environmental responsibility in industrial supply chains.
