Quality Material: The trailer deck screws are made of high quality steel with excellent anti-corrosion coating on the surface, which can effectively protect the screws and prolong their service life.
Wood to Metal: Reamer Tek screws are for applications where wood is being fastened to mild steel or aluminum，length of screw does NOT represent usable length of thread / thickness of wood – #14 x 3-1/4″ Maximum Wood depth ~2″ – Maximum Metal Thickness Screw Can Bore ~1/4″
Easy Installation: In the threaded part, we added a unique threading process, which can effectively reduce the resistance when drilling screws, with the self-tapping screw tail, without the need to cooperate with the drilling of holes, can be easily nailed into soft steel or aluminum. (Note: They will not self-drill through thicker or non-soft material, these worked great best to pre drill your holes through the wood and let them self tap into the metal. ）
Fragile Wings: After the wood is drilled through, the wings of the screw contact the steel and break off, then the threads engage.
