Professional Applications & Engineering Value
Engineered for critical applications where vibration loosening poses significant operational risks, these nylon patch locking flat head screws provide permanent thread locking without compromising disassembly capability. The 18-8 stainless steel core material, enhanced by passivated finish, delivers exceptional corrosion resistance in harsh environments including marine, chemical processing, and outdoor equipment. The combination of UNC coarse threading with Class 2A tolerance ensures rapid installation and reliable performance in metals and plastics, while the 82° flat head profile creates seamless surfaces in countersunk applications. These fully threaded screws maintain their 80,000 psi tensile strength across temperature extremes, making them ideal for automotive assemblies, machinery guards, and electronic enclosures requiring vibration-resistant fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit standards with UNC 1/4"-20 coarse threading and complete 82° countersink angle. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. The nylon patch locking technology maintains performance across the specified temperature range of -70° to 250°F while the Rockwell B80 hardness provides optimal durability without brittleness.
