Prime-Line 9056636 Hex Lag Screws, 3/8 In. X 8 In., A307 Grade A Zinc Plated Steel (10 Pack). Product ID: 15425589. Condition: New.

Lag screw bolts are used in place of standard wood screws whenever the mounting surface must bear a heavy load. Note that lag screws do not accept nuts as they are technically thick heavy duty wood screws with threads designed to cut into wood. They are ideal for use on decks since installation can be accomplished without having access to both ends of the fastener, as opposed to standard hex bolts that require a nut on the opposite end. Size: 3/8 inch X 8 inch Heavy duty wood screw with 6 sided hex bolt head
