Professional Applications & Engineering Value

These 3/8"-16 UNC brass flat head slotted screws deliver exceptional engineering value across multiple industrial sectors. The brass material provides inherent corrosion resistance, making them ideal for electrical components, marine hardware, and plumbing systems where moisture exposure is common. The partially threaded design with coarse UNC threading offers superior holding power in softer substrates while the 82° countersink angle ensures secure, flush mounting in precision assemblies. With Rockwell B50 hardness and 50,000 psi tensile strength, these industrial fasteners maintain structural integrity under vibration and load stress, solving common failure points in machinery and equipment manufacturing. The slotted drive style provides compatibility with standard tools while the right-hand thread direction ensures intuitive installation in production environments.

Specification Summary & Compliance

These flat head screws feature precision Class 2A thread fit with UNC coarse threading (3/8"-16) and are manufactured to ASME B18.6.3 specifications for dimensional accuracy. The inch system measurements include a head diameter of 0.717", head height of 0.23", and minimum thread length of 1-1/2" on a 3" overall length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures they meet international standards for restricted substances, making them suitable for global supply chains and environmentally conscious manufacturing operations.
