Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 1/4"-20 UNC hex head screws deliver critical reliability where failure is not an option. The 400 Nickel construction provides outstanding resistance to oxidation and chemical exposure, making these external hex drive fasteners ideal for marine, chemical processing, and outdoor equipment. With coarse thread spacing and partial threading, they offer superior grip in softer materials and prevent loosening under dynamic loads. The combination of 80,000 PSI tensile strength and precise Class 2A thread fit ensures consistent clamp load distribution, solving common challenges of joint integrity in heavy machinery, structural frameworks, and high-vibration environments where standard fasteners often underperform.

Specification Summary & Compliance

This hex head screw maintains precise Class 2A thread fit per UNC standards with 1/4"-20 coarse thread configuration and 2" length. Manufacturing and material quality strictly adhere to ASTM F468 and MIL-S-1222 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
