Description

A "truss head screw" is a type of threaded fastener with a wide, rounded, mushroom-shaped head, offering a large bearing surface that distributes load effectively, making it ideal for applications where a low profile and strong hold are needed, like attaching sheet metal, cabinetry, or construction framing; unlike a pan head screw, a truss head sits slightly above the surface when fully tightened due to its wider head diameter. Key points about truss head screws: Appearance: A large, rounded head that resembles a mushroom, often with a slightly undercut bottom. Benefits: Wide load distribution: The large head surface area prevents damage to the material by spreading the force applied. Low profile: Can sit flush with a surface or slightly above it depending on the application, making it aesthetically pleasing. Common applications: Sheet metal work Cabinetry Construction framing Aerospace manufacturing Comparison to pan head screws: While similar in appearance, a truss head is generally wider and has a lower profile than a pan head screw.
