Hillman Fasteners 116848 Exterior Screw 10x3.5 Inch 55 Pack

Product Description

The HILLMAN FASTENERS 116848 is a bronze epoxy coated, flat head, star drive exterior screw designed for multi-material applications. At No. 10 diameter and 3.5 inches in length, this screw is built for demanding outdoor fastening jobs where corrosion resistance and holding strength matter. The star drive recess reduces cam-out during installation, and the flat head countersinks flush into the work surface. Each package contains 55 screws, making it a practical choice for production installs or larger repair jobs. Trades and contractors who work across varied substrates will find this fastener ready for consistent performance in exterior conditions.

This screw is intended for exterior use across a range of substrates including wood, masonry, drywall, and plastic. The bronze epoxy coating provides corrosion resistance suitable for outdoor exposure. Typical applications include deck construction, exterior trim work, siding attachment, and general structural fastening on residential and light commercial projects. The multi-material design reduces the need to stock separate fastener types for different substrates on the same job site.

Installation Notes

Installation is performed with a star drive bit matched to the No. 10 screw head. Pre-drilling a pilot hole is recommended when fastening into hardwood or masonry to prevent splitting and ensure proper seating. Follow applicable building codes for fastener spacing and embedment depth, particularly when used in structural or load-bearing applications. Always wear appropriate eye protection when driving fasteners into masonry or hard substrates.
