Hillman Fasteners 116845 Exterior Screw 10x2.5 in 78 Pack

Product Description

The HILLMAN FASTENERS 116845 is a multi-material exterior screw designed for demanding outdoor and mixed-substrate fastening applications. This flat head, star drive screw features a bronze epoxy premium coating that resists corrosion in exterior environments. At a size of 10 x 2.5 inches, the screw provides strong, deep penetration for secure attachment. Licensed contractors, carpenters, and experienced DIYers install these screws across a wide range of substrates, including wood, masonry, drywall, and plastic. Each pack contains 78 screws, making it practical for medium to large projects where consistent, reliable fastening is required.

The 116845 is suited for exterior residential and light commercial construction tasks. Its multi-material designation means a single screw type can be used across different substrates on the same job site, reducing the need to switch fasteners mid-task. Typical applications include deck building, exterior trim work, fence installation, and mixed-substrate assemblies where exposure to moisture and weather requires a coated fastener with lasting hold.

Installation Notes

These screws are installed by carpenters, general contractors, and skilled tradespeople using a star drive bit and a standard power driver or drill. Always pre-drill pilot holes in masonry or hard substrates to prevent cracking and ensure proper seating. Follow applicable building codes for exterior fastener requirements, including those related to corrosion-resistant hardware in treated lumber or coastal environments. Do not overtorque, as this can strip the substrate or compromise the flush seating of the flat head.
