Hillman Fasteners 42497 Stainless Exterior Screw 35 Pack

Product Description

The HILLMAN FASTENERS 42497 is a stainless steel exterior screw designed for outdoor fastening applications where corrosion resistance is critical. Each screw measures 2 inches in length and is sized No. 9 in diameter. The self-drilling point eliminates the need for a pilot hole in most applications, speeding up installation. A knurled shank section below the head helps prevent wood splitting during drive-down. The star drive recess provides positive bit engagement and reduces cam-out. These screws are rated to withstand 2000 hours of salt spray testing, making them appropriate for coastal and high-moisture environments. Sold in a pack of 35, this SKU is suited for deck, siding, trim, and general exterior wood fastening work.

These screws are intended for exterior wood-to-wood and light composite fastening tasks in residential and light commercial construction. Typical applications include deck boards, exterior trim, fascia, fencing, and siding. The stainless steel construction makes them a preferred choice where pressure-treated lumber or consistent moisture exposure would cause carbon steel fasteners to corrode and stain the surrounding material. They are installed by carpenters, general contractors, and experienced DIYers using a star-tip driver bit.

Compatibility

Designed as a general-purpose exterior wood fastener suitable for use with pressure-treated lumber, cedar, redwood, and standard dimensional lumber in outdoor construction applications.

Installation Notes

Install with a star-tip driver bit sized to match the drive recess to avoid stripping. While the self-drilling point reduces the need for pilot holes, pre-drilling is recommended near board ends or in dense hardwoods to prevent splitting despite the knurled section. Follow local building codes for fastener spacing and penetration depth requirements on decks and structural applications. Stainless fasteners should not be mixed with dissimilar metals in direct contact to avoid galvanic corrosion.
