Do It 729965 Exterior Deck Screws 1 Lb 1-5/8 Inch

Product Description

The DO IT 729965 is a 1-pound box of 1-5/8 inch combo drive exterior screws built for demanding outdoor fastening applications. Each screw features a galvanized base with PrimeGuard Plus coating, delivering high corrosion resistance and a finish color that blends with treated lumber. The flat countersinking head allows for flush seating without surface damage. An extra-coarse thread pattern reduces wood splitting and lowers drive friction, while the Type 17 drill tip bores directly into wood without pre-drilling. Carpenters, deck builders, and general contractors working on exterior structures reach for these when they need a reliable, code-appropriate fastener.

These screws are designed for all exterior wood fastening applications including decks, docks, fences, and gazebos. The PrimeGuard Plus finish meets corrosion-resistance requirements for use with treated lumber, making them a practical choice for residential and light commercial outdoor construction. The combo drive head accepts both Phillips and slotted drivers, providing flexibility on the job site when tool options vary. The 1-pound box format suits both small patch repairs and ongoing production work.

Installation Notes

Install using a drill or impact driver fitted with a combo-drive bit sized to the head recess. Power down any adjacent electrical or lighting circuits before working on deck structures near conduit or fixture boxes. Follow local building codes for fastener spacing and penetration depth on structural decking. Do not use these screws in submerged or continuously wet conditions beyond the rated corrosion-resistance class of the coating.
