Description

Lag screw bolts are used in place of standard wood screws whenever the mounting surface must bear a heavy load. The hex head allows for lag screws to be tightened with more torque than can be used on Phillips head screws, though a pilot hole is still required prior to installation. 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.

Key Features

Diameter & Length: 1/2 inch X 4 inch

Wood screw with a 6-sided hex bolt head

Much thicker than standard wood screws

Used in applications where standard wood screws cannot support the load, excellent for deck building where you can not use nuts

Requires pilot hole to be drilled and installs using wrench or socket tool
