3/8 inch galvanized steel lag screws. Lag screws are bolts with sharp points and coarse threads designed to penetrate and grip wood similar to a wood screw. They are generally used to anchor metal or wood to wood in places where you can't use a nut for a throughbolt or where an especially long bolt would be needed to penetrate a joint fully. Although lag screws do have unique and desirable applications, throughbolts are generally considered to be a more positive means of connection since they are less dependent on workmanship for reliable installation.

MET / STD:
Can these 3/8 galvanized lag screws be used with treated wood?
Can anyone tell me what the size of the hex head is?
I use them for wooden livestock fences which have treated boards and often treated posts as well. After a lot of years the lags will look chewed up when you pull them out of the wood (which we do when we are replacing a broken board) but they last a long time.
I am a professional builder and stumbled upon this site for some stainless parts. They are the least expensive I've found. I came back for the galvanized and found the same to be true. [...] Great site, great products.
