Professional Applications & Engineering Value
These 1/4-20 UNC Torx screws with epoxy thread locker provide engineered solutions for vibration-prone industrial applications. The 18-8 stainless steel construction offers excellent corrosion resistance for outdoor equipment, marine components, and chemical processing machinery. The T27 drive system delivers superior torque transmission compared to traditional drives, reducing installation time and preventing fastener damage. With Class 3A thread precision and fully threaded design, these rounded head screws ensure secure fastening in automotive assemblies, electrical enclosures, and heavy machinery where vibration resistance and environmental durability are critical. The coarse thread spacing facilitates quick assembly while maintaining structural integrity under dynamic loads.
Specification Summary & Compliance
This 1/4-20 UNC screw features precision Class 3A thread fit with right-hand coarse threading and fully threaded shank. Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. The epoxy thread locker begins hardening in 4 hours and reaches full strength in 72 hours, maintaining effectiveness across -65° to 400°F temperature range. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
