TM nickel-plated large flat head screws, cross machine screws, mushroom head screws, and half round head bolts M3/M4/M5

The core advantages of nickel-plated flat head screws are "fit and stability, corrosion resistance and rust prevention, safety and aesthetics, and wide adaptability."

1. The large flat head design ensures a secure fit and protection. The head of the base material is a large-diameter flat umbrella-like structure, with a contact area 3-4 times that of ordinary round or countersunk screws. After tightening, it fits tightly with the surface of the workpiece, maximizing the distribution of fastening pressure and avoiding embedding into soft/thin base materials such as wood, plastic, and thin metal (preventing cracking, indentation, and perforation). The force distribution is uniform, making it less prone to loosening under minor vibrations (such as the operation of small household appliances or daily use of furniture). Its fastening stability is far superior to that of small-head screws, especially suitable for soft or thin base materials.
2. Nickel plating for protection, corrosion resistance and rust prevention + no plating peeling. The nickel plating on the surface forms a dense and highly adhesive protective layer, which can isolate the screw from air, moisture, and mild acid-base environments. Its rust resistance is 3-5 times that of ordinary carbon steel screws, making it suitable for indoor dry, mildly humid environments (such as kitchen drying areas, balconies), etc. Long-term use will not result in plating peeling or rusting. The nickel plating is odorless and environmentally friendly, suitable for use in scenarios where material safety is required, such as children's products and auxiliary fixation of food-contact equipment.
3. It is safe and aesthetically pleasing, suitable for exposed settings. The edges of the large flat head have been chamfered to be smooth and rounded, eliminating sharp corners. Daily contact will not scratch clothing, skin, or precision components (such as the internal wiring of home appliances). After nickel plating, it presents a uniform, bright silver-white color, with a clean texture. It can be matched with light-colored and metallic workpieces (such as white plastic casings, aluminum alloy profiles, and light-colored panel furniture). When the screws are exposed, they do not protrude, balancing practicality with clean appearance.
