1/4 inch

1/4 inch diameter steel lag is only available with Japanese Import Standard heads, which are smaller than the American standard heads. The heads measure 3/8" across, instead of 7/16". We offer both plain and black oxide finishes. Be sure to call if you need a size we are not offering.

Hex lag bolts, often called a lag screw, are for fastening in wood.  Blacksmiths commonly use them to attach their ironwork in homes and on buildings or structures during installation.
