KM304 stainless steel cross flat head hinge screw countersunk head machine screw

Product Specification

The core advantages of 304 stainless steel countersunk Phillips screws are "flat and concealed, corrosion-resistant and rust-proof, versatile and easy to install, and protect materials from scratching"

1. Counter-sunk structure, flat and concealed without protruding head. The head is designed as a conical counter-sunk shape, which can be fully embedded into the counterbore of the workpiece after tightening, flush with the surface of the base material, without protruding parts. Safety and scratch resistance: It prevents scratching skin, clothing, or interfering with moving parts of equipment (such as drawer slides, cabinet door hinges) during daily contact, especially suitable for high-frequency contact scenarios such as furniture panels and children's products. Beautiful and tidy: When exposed, there are no protruding screw heads, visually simpler, suitable for decorative assembly scenarios (such as wall decorative panels, precision instrument housings), without the need for additional covers.
   Pressure dispersion: The mating surface of the countersunk head and the counterbore can evenly disperse the tightening pressure, preventing thin plates and soft substrates (such as plastic and wood) from sagging or cracking due to excessive local stress
2. 304 stainless steel material, featuring all-scenario corrosion and rust resistance with an alloy composition of 18% chromium and 8% nickel, forms a dense oxide film on the surface, which can resist the erosion of moisture, salt spray (non-coastal high concentration), mild acids and alkalis, and daily cleaning agents:
   Outdoor scenes (such as balcony railings and sunshade fixings) will not rust after long-term use, avoiding contamination of the substrate or failure of fastening due to corrosion of carbon steel screws;
   Indoor humid environments (such as kitchen cabinets and bathroom accessories) pose no risk of plating peeling off, and there is no yellowing caused by rust, ensuring the workpieces remain clean and tidy;
   The material is non-magnetic, environmentally friendly, and non-toxic, making it suitable for use in scenarios where safety is a priority, such as food machinery and children's furniture. Its service life is 4-6 times longer than that of carbon steel galvanized countersunk screws.
3. Cross recess drive, universal, convenient, and easy to operate. The cross recess is a globally recognized drive slot type, compatible with both ordinary screwdrivers and electric screwdrivers, eliminating the need for specialized tools. Low learning curve: With precise positioning, even novices can easily align the slot opening, avoiding the issues of "misalignment and difficulty in turning" encountered with specialized slot types such as hexagonal sockets. Efficient application scenarios: Ideal for home DIY, renovation sites, factory mass assembly, and other scenarios. Electric screwdrivers can quickly complete disassembly and assembly, significantly saving labor time. Low risk of slipping: The depth and width of the slot opening are designed to accommodate conventional tools, making it less likely for the slot opening to wear and slip (slip) under normal torque, ensuring convenient maintenance.
