- โ SPECIFICATIONS: Size: 1/4-20 Thread x 2-1/4" Length. Drive: T-30 Star/Six-Lobe (Prevents cam-out). Head: Flat Countersunk (Sits flush). Material: Alloy Steel with Black Phosphate finish. Quantity: 30 Screws.
- ๐ฉ TYPE F THREAD CUTTING: Features a blunt tapered point with multi-cutting edges. Designed to cut its own threads into heavy-gauge sheet metal, aluminum, cast iron, or steel structural members. Note: Requires a pre-drilled pilot hole.
- ๐ TRAILER DECKING APPLICATION: specifically engineered for re-decking flatbeds, dry vans, utility trailers, and truck beds. The "Floorboard" design features a flat head that countersinks into the wood, creating a smooth, trip-free surface.
- ๐ง T-30 STAR DRIVE: The 6-lobe recess creates a positive grip that withstands high-torque driving without slipping or stripping (cam-out), which is essential when driving screws into thick metal crossmembers.
- ๐ก๏ธ HEAVY DUTY STEEL: Made from hardened Alloy Steel for superior tensile strength. The Black Phosphate coating retains oil and provides basic corrosion resistance and lubricity during the thread-cutting process.
