Hillman Fasteners 47879 Construction Lag Screws 60 Pack

Product Description

The HILLMAN FASTENERS 47879 is a 60-pack of Power Pro Bronze Ceramic Construction Lag screws sized 6 inches by 5/16 inches. These lags feature a Type 17 cut point for cleaner entry into wood and a star drive head for high-torque installation. The coarse, serrated thread pattern provides aggressive holding power in structural and heavy-duty construction applications. The Bronze Ceramic coating delivers a 1500-hour salt spray rating, making these screws well-suited for treated lumber and exterior exposure. Licensed contractors and framing crews are the primary installers for this type of fastener.

These construction lags are designed for structural wood connections in residential and light commercial framing, decking, ledger boards, post anchors, and similar applications where a corrosion-resistant fastener is required. The 6-inch length and 5/16-inch diameter make them appropriate for heavy timber connections and through-bolting scenarios where a lag screw is specified. The Bronze Ceramic finish is compatible with ACQ, CA, and other preservative-treated lumber commonly used in exterior construction.

Key Features

• Type 17 cut point reduces splitting and allows self-starting entry into wood without pre-drilling in many applications
• Star drive head design delivers higher torque transfer and reduces cam-out compared to hex head or Phillips drive
• Coarse serrated thread pattern provides high withdrawal resistance in dimensional and engineered lumber
• Bronze Ceramic coating rated to 1500 hours of salt spray resistance for long-term exterior durability
• Compatible with ACQ and other preservative-treated lumber commonly used in decks and exterior framing
• Lifetime warranty included per manufacturer specification

Compatibility

Designed for structural wood-to-wood connections in exterior and interior construction framing, decking, and ledger applications where a 5/16-inch diameter, 6-inch length lag screw is specified. The Bronze Ceramic coating is suitable for use with treated lumber.

Installation Notes

Installation should be performed by a qualified carpenter or contractor following applicable building codes, including IRC framing and deck construction provisions. A pilot hole is recommended in denser lumber species to prevent splitting and ensure proper seating. Use a star drive bit of the correct size to avoid bit wear and cam-out. Always verify fastener sizing and spacing against local code requirements or engineer specifications for structural connections.
