Professional Applications & Engineering Value
Engineered for critical industrial fastening applications where vibration resistance and environmental durability are paramount. The nylon patch locking technology creates permanent friction against mating threads, eliminating the need for secondary locking components in machinery, electrical enclosures, and transportation equipment. The 18-8 stainless steel composition provides excellent corrosion resistance in moist or chemical environments, while the UNC coarse threading with Class 3A fit ensures rapid assembly and reliable performance in high-vibration settings. The flat head design with 82° countersink angle offers flush mounting for applications requiring smooth surface profiles.
Specification Summary & Compliance
This 8-32 x 1" flat head screw features UNC coarse threading with precision Class 3A thread fit and complete threading along the 1" length. Manufactured to meet MIL-DTL-18240 specifications for quality assurance. Compliance certifications include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for environmental safety standards. The fastener maintains dimensional accuracy with standard 82° countersink angle and 3/32" hex drive configuration for consistent performance across industrial applications.
