M4 x 20mm nickel-plated carbon steel self-tapping screws with Phillips pan heads. Smooth, burr-free threads suit wood, drywall, furniture, metal and plastic applications.
Quick, secure fixings – With M4 self-tapping threads
Self-tapping threads cut mating threads as driven, so the screw forms its own engagement without routine pre-drilling in many materials. Uniform pitch and clean thread profiles reduce effort when driving into wood, plastic or thin metal.
Faster installations save time on small jobs and repairs, producing neat joints with reliable thread engagement.
Resists corrosion – With nickel-plated carbon steel
Nickel plating over carbon steel increases surface hardness and creates a barrier against moisture, helping to limit surface corrosion. Carbon steel core provides strength while the plating reduces exposure to rust.
Longer-lasting fastenings mean fewer replacements and more reliable joints in typical indoor and light-humidity environments.
Neat, easy drive – With Phillips pan head and smooth finish
Pan head geometry offers a broad bearing surface for stable seating, while the Phillips drive mates cleanly with common screwdrivers. Smooth, burr-free manufacture ensures consistent seating and lowers the risk of catching or splitting materials.
Professional-looking assemblies and reduced risk of stripped heads make furniture assembly and general repairs less fiddly.
