Do It 737586 Exterior Combo Drive Deck Screws 1 Lb

Product Description

The DO IT 737586 is a 1-pound box of extra coarse thread combo drive exterior screws designed for demanding outdoor fastening applications. These screws feature a galvanized base with a PrimeGuard Plus coating that delivers high corrosion resistance and long service life. The flat countersinking head sits flush with the surface for a clean finish, and the color is formulated to closely match the appearance of treated wood. A Type 17 drill tip allows the screw to drive directly into wood without pre-drilling, saving time on the job. The thread pattern is engineered to reduce wood splitting and minimize friction during installation.

These exterior screws are suited for residential and light commercial outdoor construction work. Typical applications include decks, docks, fences, and gazebos. The screws are compliant for use with treated lumber, making them appropriate for ground-contact and above-ground pressure-treated wood installations. Carpenters, general contractors, and experienced DIYers regularly specify this type of fastener where long-term corrosion resistance and structural hold are required in exposed outdoor environments.

Installation Notes

Installation is performed by carpenters or general contractors using a standard combo-drive bit at the appropriate driver speed to avoid overdriving the countersinking head. Power down or unplug any adjacent electrical equipment before working in the immediate area. No pre-drilling is required when using the Type 17 drill tip, but pilot holes may be advisable near board ends to prevent splitting. Follow applicable local building codes for fastener spacing and penetration depth on structural deck framing.
