Wood Lag Screws

Has superior corrosion resistance to galvanized steel bolts.

Wood lag screws. These wood screws boast coarse threading but that threading does not encompass the length of the screw. Most lag screws are manufactured out of galvanized steel and available in wide range of sizes. The most common stainless steel for general hardware use.

Both wood screws and lag screws differ from sheet metal screws which have threads all along the shaft. Normal wood screws thread as they enter the wood where lag screws require a hole to be drilled first. In most instances 516-inch-diameter lag bolts are sufficient.

A lag screw also known as a lag bolt is a fastener that has a hex head and external hex drive and coarse threads that extend a minimum two-thirds of the shaft length. Select a lag bolt thats 14 inch shorter than the accumulated width of the two pieces. A full-bodied bolt with hex head spaced threads and a gimlet point.

However since wood screws are normally smaller than lag screws and dont use nuts they cant bear the loads that lag screws can. Performance. A corrosion resistant steel alloy.

Clamp together two pieces of wood the sizes of the ones you want to screw together. The tight fit of the wood screw negates the need for a nut. LAG SCREW JOINTS 3 ture content of the wood made a difference of about 2 percent in the results for the screws and 3 percent for the nails and bolts.

Align the wood sections of your construction project and hold them together with wood clamps. A lag screw is used to fasten wood to wood in applications where strength is required. Their threads are much two three even four times thicker than those of regular screws and so they provide a lot of support.
