Description

A countersunk, six-lobe (torx) thread cutting screw with machine screw thread pitch, blunt point, tapered entering threads, and multiple cutting edges. Floorboard screws are, by definition, available in much longer sizes than standard type-F screws. Common For Trailer Flatbed Also Called “Six Lobe” Also Called “Star Drive” Also Called “Decking Screw” Black Phosphate Will Thread Into A Pre-Drilled Hole Tapping Point = “F” Type of screw: Thread cutting screws Screw type: Type F Material: Alloy steel Coating: Black phosphate Drive type: Star drive (also known as Torx drive) Head type: Flat head These screws are designed to cut their own threads into materials such as wood or plastic, eliminating the need for a pre-drilled hole. The black phosphate coating provides some resistance to corrosion and wear, making these screws suitable for outdoor applications. The star drive provides better grip and less slippage compared to other drive types, allowing for easier and more efficient installation. The flat head allows for a flush installation, making it a good choice for applications where a smooth surface is desired. These screws are specifically designed for use in floorboard trailer decks, where they can provide a secure and durable fastening solution.

  • Really nice bolts - TORX is the way to go T30 is awesome for driving the screw
Item Package Quantity: 100 Size: 1/4-20 x 1 inch
Need to replace about 100 bolts in a toy hauler trailer. It has Logistic L-Track aka airline track for tie down locations. the OE installed undercut flat head screws are having heads breaking/pooping off!! Already had 6 broken bolts like this! I had to use a drill and broken screw extractor to get the broken self tappers out. A real chore!! They are way to tight! But the new screws look great, these are not undercut, but "self drilling" and the threaded hole is already there in the floor, so these are installing easily. TORX is the way to go on fasteners! Better than hex head and FAR better than Phillips (all my L-Track is installed with Phillips).. Happy to replace all of them over time. ... show more
