Large Flat Head Machine Screws
Oversized Truss Head / Phillips Cross Recess
Our large flat head machine screws feature an oversized truss-style head that provides a significantly wider bearing surface than standard pan head or round head screws. This design distributes clamping force over a larger area, making them ideal for fastening thin sheet materials, soft substrates, and applications where pull-through resistance is critical. Manufactured through precision cold heading with Phillips cross recess drive for reliable installation.
