Professional Applications & Engineering Value
This 1/4"-20 stainless steel pan head screw is engineered to address common industrial challenges such as vibration-induced loosening and corrosion. The combination of 18-8 stainless steel material and passivated finish provides excellent resistance to rust and chemical exposure, making it ideal for outdoor equipment, marine applications, and food processing machinery. The integrated internal-tooth lock washer, made from 410 stainless steel, bites into surfaces to maintain clamp load under stress, eliminating the need for additional locking components. With UNC coarse threads and a Class 2A fit, it ensures quick assembly and reliable performance in metals, plastics, and composite materials, reducing downtime and maintenance costs in industrial screw applications.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 2A tolerance for precise fit, fully threaded along a 1" length. It meets ASME B18.13 specifications for dimensional consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are adhered to in industrial settings.
