304 stainless steel UNC US imperial hex flat head chamfer screws and nuts are precision fastener sets engineered for furniture assembly, splint fixation, and anti-loose pairing applications. Compliant with UNC (Unified National Coarse) standards, these imperial-size fasteners combine 304 stainless steel’s corrosion resistance with a hex flat head, chamfered design, and pair lock functionality for reliable performance in US-standard projects.
Crafted from premium 304 stainless steel, the set offers excellent rust resistance, making it suitable for indoor furniture, woodworking, and light industrial assemblies—ideal for humid environments or visible installations. The hex flat head sits flush with surfaces for a clean aesthetic, while the chamfered edges ensure smooth insertion into imperial tapped holes. The pair lock design enhances anti-loose stability, preventing loosening from vibration or frequent use, and the UNC coarse threads guarantee secure engagement in wood, composite, or metal workpieces.
Designed for versatility in furniture manufacturing, wood splint fixation, and custom US-standard assemblies, the screw-nut set ensures seamless compatibility with imperial tools and workpieces. The flat head design avoids protrusions, keeping surfaces neat, making it perfect for visible furniture joints.
