Size Runs and Matching Washers Kits
Stainless Steel Hex Lag Bolts in variable, custom ready durable boxes. Hex Lag Bolts are also known as Hex Lag Screws. Hex Lag Bolt kits include a variety of diameters and lengths, but typically contain a size run of a particular type of fastener.
Lag bolts, also called lag screws, are basically "large wood screws". A typical lag bolt is a 6 inches long, 1/4 diameter screw with coarse threads of a wood-screw or sheet-metal-screw threadform (but larger). The head is typically an external hex. The materials are stainless steel for corrosion resistance. Lag bolts are used to lag together lumber framing, to lag machinery feet to wood floors, and other heavy carpentry applications. These fasteners are clearly "screws" when defined by the Machinery's Handbook distinction. The term "lag bolt" has been replaced by "lag screw" in the Machinery's Handbook. However, in the minds of most tradesmen, they are "bolts", simply because they are large, with external-hex heads. In the United Kingdom, lag bolts/screws are known as coach screws.
