Do It 729983 Exterior Combo Drive Deck Screw 1 Lb

Product Description

The DO IT 729983 is a galvanized exterior deck screw designed for outdoor fastening applications where corrosion resistance and long-term performance matter. Built with a Dec-Smart galvanized base and PrimeGuard Plus coating, the screw delivers high corrosion resistance and a color finish that blends with treated lumber. The flat countersinking head sits flush on installation. The Type 17 drill tip drives directly into wood without pre-drilling, saving time on the job. Sold in a 1-pound box, these screws are a practical choice for deck builders, fence installers, and general exterior carpentry.

These screws are suited for exterior wood construction including decks, docks, fences, and gazebos. The extra coarse thread pattern reduces wood splitting and minimizes friction during drive, making them appropriate for pressure-treated lumber, dimensional lumber, and similar structural wood materials. The combo drive head accepts both Phillips and slotted bits, reducing the chance of cam-out on high-volume jobs. Compliant for use with treated lumber.

Installation Notes

Installation is typically performed by carpenters, deck builders, or general contractors using a power drill or impact driver fitted with a combo-drive bit. No pre-drilling is required thanks to the Type 17 drill tip, but pilot holes are recommended near board ends to reduce splitting risk. Follow local building codes for fastener spacing and penetration depth on structural decking assemblies. Store unused screws in a dry location to maintain coating integrity.
