Prime-Line Products 9055346 Lag Screw Bolt, Hex Head, 1/4 in X 5 in, Zinc Plated Steel, Pack of 100

• Diameter & Length: 1/4 inch X 5 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

Lag screw bolts are used in place of standard wood screws whenever the mounting surface must bear a heavy load. They are often used on heavy lumber. Due to the thicker diameter, a pre-drilled pilot hole is required. The hex head allows for it to be tightened with more torque than can be used on a phillips head screw.
