Professional Applications & Engineering Value
These brass oval head slotted screws deliver exceptional performance in demanding industrial environments where corrosion resistance and reliable fastening are critical. The UNC coarse thread design ensures quick installation and superior holding power in soft materials and high-vibration applications. The standard oval head profile with 82° countersink angle provides a clean, finished appearance while maintaining structural integrity. Particularly valuable in marine hardware, electrical enclosures, and industrial equipment, these screws combine the non-magnetic properties of brass with 50,000 psi tensile strength to prevent galvanic corrosion while maintaining mechanical reliability. The fully threaded 1-1/2" length offers maximum thread engagement for secure connections in various material thicknesses.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC 1/4"-20 coarse thread specifications. Complies with ASME B18.6.3 mechanical and dimensional requirements, ensuring interchangeability and reliable performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, confirming the absence of restricted hazardous substances. The right-hand thread direction and standard oval head profile maintain industry-standard installation practices.
