Professional Applications & Engineering Value

This 3/8"-16 UNC brass flat head screw is engineered to address common industrial challenges such as corrosion-induced failure and assembly inefficiency. The brass material offers inherent resistance to rust and galvanic corrosion, making it ideal for marine, plumbing, and electrical applications where moisture exposure is frequent. Its coarse thread design ensures rapid installation in soft metals or plastics, while the hex drive allows for secure torque application without slippage. The flat head with 82° countersink provides a smooth, flush finish that minimizes protrusion in machinery and consumer products. With a Rockwell B55 hardness and 50,000 PSI tensile strength, it maintains integrity in vibrating environments, reducing maintenance needs and downtime in industrial fastening systems.
