Buying Guide

Match screw thread to material

Use thread forming screws for ductile materials like aluminum and some plastics, and thread cutting screws where hard or brittle materials require a pre-cut thread to avoid split or stress

Pick the right point type

Type F or other self-tapping points are designed for floorboards and deck applications to create threads in wood-to-metal assemblies without pre-tapping

Consider drive and installation tool

Six-lobe (Torx) drives reduce cam-out and are common on trailer and decking screws for consistent torque and less stripping

Choose finish for corrosion resistance

Black-phosphate and other coatings offer basic corrosion protection for indoor or covered applications; select higher-corrosion finishes for marine or exposed environments

Balance length and diameter with load

Select screw length and diameter (e.g., 1-1/2" to 3.5" lengths, 1/4" to 3/8" diameters in our list) to ensure adequate pullout resistance and shear capacity for trailer-deck and floorboard fastening
