Hillman Fasteners 116805 Exterior Screw 10x3.5 Flat Head 12 Pack

Product Description

The HILLMAN FASTENERS 116805 is a multi-material exterior screw designed for demanding outdoor and structural fastening applications. This flat head, star drive screw measures No. 10 x 3.5 inches and features a bronze epoxy premium coating that resists corrosion in exterior environments. Sold in a 12-pack, these screws are engineered for use across a range of substrates, making them a versatile choice for trade professionals handling mixed-material assemblies. The flat head profile sits flush with the surface, and the star drive recess provides high torque transfer with reduced cam-out during installation.

These screws are suited for residential and light commercial exterior work where a single fastener must perform across multiple substrate types. Typical applications include decking, trim, and framing assemblies that involve combinations of wood, masonry, drywall, and plastic. The bronze epoxy coating makes them appropriate for installations exposed to moisture and the elements. Licensed carpenters, general contractors, and experienced trade professionals will find these useful for reducing inventory by covering multiple fastening needs with one screw specification.

Installation Notes

Installation is typically performed by carpenters, general contractors, or qualified tradespeople using a star drive bit and a variable-speed drill or impact driver. Pre-drilling a pilot hole is recommended when fastening into masonry or dense hardwood to prevent substrate cracking and reduce drive stress. Ensure the correct bit size is seated fully in the recess before driving to maintain the star drive geometry and avoid stripping. Follow applicable local building codes for fastener spacing and load-bearing requirements when used in structural assemblies.
