Lag Screws / Lag Bolts

Lag bolts, also known as lag screws, are a type of fastener designed for heavy-duty applications where a strong and secure connection is essential. These bolts are characterized by their coarse threads and a hexagonal head, allowing for efficient installation with a wrench or socket.

Lag bolts are commonly used in construction, woodworking, and other structural projects where stability and load-bearing capacity are crucial. Their large size and robust design make them suitable for tasks such as attaching heavy lumber, securing structural elements, or joining materials that require a durable and long-lasting connection.

Lag bolts come in various lengths and diameters to accommodate different project requirements, providing a versatile solution for applications that demand reliable and sturdy fastening.

Stainless steel lag bolts are preferred for their corrosion resistance, durability, and aesthetic appeal. They excel in outdoor or marine projects, maintaining a sleek appearance over time. Additionally, their low maintenance, non-reactive properties, and temperature resistance make them suitable for various applications, ensuring a strong and reliable connection.

Thread Length: The minimum thread length for standard lag screws shall be equal to ½ the nominal screw plus .5” or 5”, whichever is shorter. Screws too short for this formula shall be threaded as close to the head as practical.

Lag Screw Applications

Fully threaded lag screws are designed specifically for attaching track brackets and flag brackets of garage door assemblies to wooden door jams. They are a fully threaded fastener with a spaced thread pitch, tapered point, and an integrally formed hex washer head with an indented top surface.
