Product Details
✓Pre Drilling Required for Safe Installation: these heavy duty 5/16"-18 trailer deck screws are designed to self-tap into properly sized pilot holes; They are not self drilling; Pre drill through the flooring and metal frame before installation; The recommended pilot-hole size is 1/4" or 17/64", depending on the thickness and hardness of the steel plate; Never force drive the screws directly into solid steel, as excessive resistance may damage the screws or strip the driver bit
✓Self Tapping Type F Thread Cutting Tip: featuring Type F fluted cutting slots, these screws cut clean mating threads into properly pre-drilled metal frames or dense wood while helping clear debris during installation; The thread-cutting design provides a strong, secure connection between trailer floors and metal frames without requiring nuts; Pre drilling is required before installation
✓T40 Star Drive Flat Head: the heavy duty T40 star drive provides strong bit engagement and efficient torque transfer, helping reduce slipping and stripping during installation; The countersunk flat head sits flush with the trailer deck to create a smooth surface for safer loading and unloading; For best results, use a fresh, correctly sized T40 bit and keep the driver aligned with the screw
✓Quality Material: trailer floor screws are made of alloy steel with black phosphate coating on the surface, which is resistant to rust and has nice corrosion and wear resistance under harsh environment, with hardness and no deformation
✓6 Piece Value Pack: get everything you need for your trailer applications with our comprehensive bundle of 6 pieces, 5/16-18 X 2 1/2 inch trailer deck screws; These screws are not just ideal for flatbed trailers but also ideal for floor deck trailers, curtains and dry vans
