Hillman Fasteners 116788 Exterior Screw 8x1.5 in 25 Pack

Product Description

The HILLMAN FASTENERS 116788 is a multi-material exterior screw designed for demanding outdoor and mixed-substrate fastening applications. This is a flat head, star drive screw finished with a bronze epoxy premium coating that resists corrosion in exterior conditions. Sized at No. 8 x 1.5 inches, it is engineered to drive cleanly into wood, masonry, drywall, and plastic without requiring pre-drilling on compatible materials. Each package contains 25 screws. Installation professionals including carpenters, general contractors, and remodelers rely on this fastener where a single screw must perform across multiple substrate types in exterior environments.

This screw is suited for residential and light commercial exterior applications. Common uses include decking trim, exterior sheathing, window and door casing attachment, and composite or PVC trim board installation. The multi-material design makes it a practical choice on job sites where installers encounter mixed substrates and need a single fastener solution. The flat head profile sits flush with or below the work surface, making it appropriate for finished assemblies where a clean face is required.

Installation Notes

Installation is typically performed by carpenters, finish contractors, or general tradespeople using a star drive bit matched to the screw recess size. For masonry applications, a pilot hole is recommended to prevent substrate cracking and to ease drive-in. Follow applicable building codes for exterior fastener corrosion resistance requirements, particularly in coastal or high-moisture environments. Do not overdrive — seat the flat head flush to the surface to maintain holding strength.
