Stainless steel US Imperial UNC/UNF set screws are precision industrial fasteners engineered for locking, positioning, and stopping applications in American-standard equipment. Available in both UNC (coarse thread) and UNF (fine thread) variants, these hex flat end stop screws deliver reliable fastening for machinery, automotive assemblies, tooling fixtures, and precision mechanical setups that demand tight thread engagement and anti-loosening performance.
Crafted from high-quality stainless steel, the screws offer excellent corrosion and rust resistance, ensuring durability in indoor/outdoor industrial environments and mild chemical exposures. The UNC coarse threads provide strong load-bearing engagement for heavy-duty applications, while UNF fine threads offer enhanced precision and stability for delicate positioning tasks. The hex flat end design enables flush mounting without protrusions, avoiding interference with moving parts, and the internal hex drive ensures precise torque control during installation.
