Truss head Phillips self-tapping screws are a type of fastener commonly used in construction, woodworking, and other industries. They are designed to create their own threads when driven into materials such as wood, plastic, or metal, eliminating the need for pre-drilling or tapping.

The truss head refers to the shape of the screw head, which is slightly rounded with a low profile. This design provides a larger surface area for distributing the load and offers a neat and finished appearance once installed. The truss head also provides some level of tamper resistance, as it is difficult to remove without the proper tools.

The Phillips drive is a cross-shaped recess on the screw head, which requires a compatible Phillips screwdriver for installation. This drive type allows for increased torque transfer and reduced cam-out (slipping of the screwdriver) compared to other drive types.

Self-tapping screws have a sharp, pointed tip that acts as a drill bit, allowing them to cut their own threads as they are driven into the material. This feature makes them ideal for applications where a secure and efficient fastening solution is needed.

Truss head Phillips self-tapping screws are commonly used in industries such as construction, furniture manufacturing, automotive, and electronics. They are versatile and reliable fasteners that offer ease of installation and a secure hold in a wide range of materials.
