Lag Screws and Bolts

For anyone in construction, woodworking or any other line of work or hobby that utilizes hardware, lag screws stand out from other similar products. Typically much larger than many types of screws such as wood screws or sheet metal screws, structural lag screws are in most cases a minimum of one-inch long and 1/4-inch thick and are only thread about three-quarters of the way up the shaft. A nut is used in conjunction with the screw to secure it in place for enduring strength and stability.

Lag screws are a smart choice for jobs using heavy lumber and weighty materials and loads. To install, materials are secured in place, often using clamps, and a hole is drilled in a thinner diameter and to the full length of the lag screw. Depending on the head type, you'll use a ratchet, nut driver or another appropriate tool to screw the part in place. 

At Construction Fasteners & Tools, we carry a complete selection of lag bolt sizes ranging from a 1/4-inch to 3/4-inch thick and one inch to 16 inches long. Our structural lag screws are available with zinc, stainless steel and galvanized plating. The most common type of these screws come with a hex head. However, we also offer lox and torx self-tapping lag screw options.
