High-quality material and finish: made from durable, high-hardness metal that resists wear. Designed for use in damp environments and engineered to minimize rust over time. Smooth, burr-free machining: each fastener is finished cleanly to prevent slipping during installation and to avoid damage to workpieces or skin. Head-driven design for easier installation: the head shape and drive interface reduce cam-out and make driving faster and more controlled, saving time on every job. Deep, well-defined threads: provide strong holding power and high pull-out resistance for secure connections, with even force distribution and reliable locking. Wide compatibility: suitable for household repairs, workshop projects, handicrafts, cabinets and handles, locks, furniture assembly, construction tasks, marine applications, and woodworking. Consistent performance: engineered for repeatable, reliable results across multiple materials and applications, reducing rework and improving long-term stability. Practical use scenarios Kitchen cabinet handles: fasten handles and hinges securely with deep threads for a tight fit that resists loosening during daily use. Boat repairs and marine fittings: use in damp or salt-exposed environments where rust resistance and durable holding power are critical. Furniture assembly and carpentry: ideal for assembling solid joints, attaching locks and hardware, and securing trim where clean installation and strong pull-out strength matter. What you get Durable, rust-resistant fasteners with smooth finishes and a head design that eases driving Strong, deep threads for secure locking and high extraction resistance Versatile use across home, workshop, construction, marine, and woodworking projects
