Hillman Fasteners 47868 Bronze Ceramic Lag Screws 35 Pack

Product Description

The HILLMAN FASTENERS 47868 is a 35-pack of Power Pro Bronze Ceramic Construction Lag Screws designed for heavy-duty fastening in demanding outdoor and structural applications. Each screw measures 2.5 inches in length by 5/16 inches in diameter and features a Type 17 cut point for clean entry into wood without pre-drilling in many cases. The bronze ceramic coating delivers a 1500-hour salt spray rating, making these lags suitable for corrosive environments where standard zinc or galvanized hardware degrades quickly. A coarse thread with serrated shank improves pull-out resistance in dimensional lumber and engineered wood.

These lag screws are used in residential and light commercial construction where corrosion resistance is a priority. Typical applications include deck framing, ledger board attachment, dock construction, fencing, and coastal or marine-adjacent structural connections. The Star drive head reduces cam-out during installation and is compatible with standard T-25 or T-27 star bits depending on configuration. Each pack contains 35 screws, making it practical for mid-size framing or fastening jobs without excessive surplus.

Key Features

• Bronze ceramic coating rated for 1500-hour salt spray resistance

Compatibility

Designed as OEM-style construction lag screws suitable for use in dimensional lumber, engineered wood framing, and outdoor structural assemblies where corrosion-resistant fasteners are required.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced trade professionals. Pre-drilling a pilot hole is recommended for dense hardwoods or near board ends to prevent splitting. Use a star-drive bit rated for impact drivers to maintain torque control and avoid head damage. Always follow applicable building codes for structural fastener schedules and spacing requirements.
