Product Description

Also known as Lag Bolts, Lag Screws come in longer lengths than wood screws and are easy to tighten with a wrench.

Steels are designated by a 4 number SAE Steel grade.  The first two digits indicate the primary materials used to form the steel.  The last 2 digits identify the percentage of carbon for the alloy (in hundredths).  The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch).  Zinc Plating helps to prevent corrosion.

Hex head fasteners can be driven with simple wrenches, and require minimal clearance above the fastener because they can be driven or loosened from the side.

Thread Size: 5/16"Thread Coverage: Fully ThreadedFastener Size: #10-12Number of Items: 10Overall Length: 2-1/2 Verified Purchase
I've purchased this product three times. In each case, one or more bolts (out of 10/package) sheared off as I screwed them into pre-drilled holes in wooden posts/studs using only a hand socket wrench. Perhaps my holes aren't wide enough? But shearing is occurring inconsistently, despite the hole width. In other words, some bolts shear in a given hole width while others do not.

In my latest purchase of 10, 5 out of 6 bolts sheared off before they were in all the way. I gave up after that. All these were in one particular post. Perhaps the wood on this old beam is particularly hard/dense?

I'm guessing that these bolts would be fine on modern 2x4s which are not as dense as the ones in this old house.

They are lag screws. Heads can twist off it using an impact wrench to install.
