The HILLMAN FASTENERS 116781 is a No. 6 x 0.625-inch flat head exterior screw designed for multi-material applications in residential and commercial construction. Finished with a bronze epoxy premium coating for corrosion resistance, each screw features a star drive recess that reduces cam-out during installation. The flat head profile sits flush with or countersinks cleanly into the work surface. Sold in a 50-count pack, these fasteners are suited for trim carpenters, framers, and general contractors working across a range of substrates.
These screws are built for exterior use where weather exposure and substrate variety are common job-site conditions. Approved substrates include wood, masonry, drywall, and plastic, making them a versatile option when a single fastener needs to perform across multiple materials on the same project. The bronze epoxy coating is matched to exterior environments where moisture contact is expected.
Designed as a multi-material exterior fastener suitable for wood, masonry, drywall, and plastic substrates in residential and light commercial construction.
Installation is performed by carpenters, framers, or general trades using a star drive bit matched to the screw size. Pre-drilling a pilot hole is recommended when fastening into hardwood, masonry, or dense plastic to prevent substrate splitting and reduce drive torque. Ensure the drive bit is fully seated in the recess before applying torque to avoid stripping. Follow applicable building codes for fastener spacing and edge distances when used in structural or shear applications.
