Professional Applications & Engineering Value
This 18-8 stainless steel hex head screw with integrated flange is engineered to address common industrial fastening challenges, such as vibration-induced loosening and uneven load distribution. The UNC coarse thread design enables quick assembly in soft materials or where rapid installation is critical, while the external hex drive offers high torque capability for secure tightening. Its fully threaded 3/4" length ensures consistent holding power across joints, making it ideal for machinery, automotive assemblies, and structural frameworks where durability and corrosion resistance are paramount. The flange acts as a built-in washer, spreading clamp load effectively to protect sensitive surfaces and maintain joint integrity under dynamic loads.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 2A fit for standard tolerance applications, ensuring reliable thread engagement. It is manufactured in compliance with ASME B18.6.3 specifications, guaranteeing dimensional accuracy and performance consistency. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for industrial use.
