Lag Screws

Hex Head Lag Screws


Hex head lag screws from ITA Fasteners are screws used on tough timbers and hence, often knows as one of the toughest non-industrial screws. They can be used for fastening dense timbers with other dense timbers or thin metals. The screws come in a huge size, with a length of one inch and a thickness of quarter inch. In addition to this, they have coarse threads which do not run the entire length of the screw. These screws require a pilot hole to be drilled before being drilled into place. It is advisable to use a nut to secure the fastening in place.

Due to the sheer size and strength of these screws, they can handle heavy duty applications with ease. Since the impact of the screws on the surface can be huge, all the components which need to be assembled have to be aligned before using the screws. It is impossible to disassemble a structure once it has been fastened using lag screws. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
