Materials and Finishes

Self-Drilling Screws come in grades matched to the load, from carbon steel through high-strength alloy and corrosion-resistant stainless, with finishes from plain and zinc through hot-dip galvanized for outdoor and washdown service. Pair them with drywall screws, construction screws, and Finished Hex Nuts to round out the assembly.

How to Choose

Start with the diameter, thread pitch, and length your assembly needs, then choose a grade that carries the working load and a finish suited to the environment. Step up to alloy or stainless when strength or corrosion resistance is critical.
