304 stainless steel UNC imperial socket head cap screws are industrial-grade fasteners engineered for American-standard assemblies, featuring coarse threads, half-thread design, and a knurled socket head. Crafted to comply with UNC (Unified National Coarse) specifications, these imperial-size screws combine 304 stainless steel’s corrosion resistance with functional knurling and half-thread structure for versatile industrial, automotive, and machinery applications.
Made from premium 304 stainless steel, they offer reliable rust and corrosion resistance, suitable for indoor/outdoor assemblies, general industrial environments, and light chemical exposure. The UNC coarse threads ensure secure engagement in imperial tapped holes, while the half-thread design balances firm fixation (full thread base) with flexible installation. The knurled socket head enhances grip during manual adjustment and tool alignment, paired with a hex drive for efficient torque application and stable tightening.
Designed for compatibility with American imperial systems, they’re ideal for machinery repairs, automotive components, industrial fixtures, and custom assemblies requiring UNC standards. The socket head cap design provides a low-profile finish, avoiding interference with adjacent parts, while the knurling adds practicality for quick, tool-free adjustments when needed.
