Wafer head Self Drilling Screw M4.5*16

Truss head screw is a specialized fastener distinguished by its low-profile, wide-diameter head—a design that balances minimal surface protrusion with enhanced contact area, preventing damage to clamped materials while ensuring secure installation. It features uniform external threads (available in machine-thread or self-tapping variants) that enable tight engagement with pre-tapped holes or self-forming threads in softer substrates like wood, plastic, or thin metal.

Wafer head Self Drilling Screw M4.5*16 Material:

Constructed from durable materials such as 304/316 stainless steel (for corrosion resistance in indoor/outdoor use), carbon steel (for high tensile strength), or alloy steel (for heavy-duty applications), this screw is often finished with zinc plating, nickel coating, or passivation to boost rust resistance and aesthetic appeal. Its truss head design makes it ideal for scenarios requiring a smooth, low-profile finish, such as electronic enclosures, furniture assembly, household appliances, and light-duty mechanical equipment—where it avoids snagging on fabrics or interfering with moving parts while delivering reliable holding power.
