square headed lag bolts
At my work place I came across a bunch of old lag bolts of different lengths and diameter that all have square heads instead of hex. I tried using different normal wrenches and sockets on them but none will fit right. I showed them and asked at the hardware store if they knew of a wrench or socket used for these and they said they said they'd never even seen square headed lag bolts. I googled a little and found that apparently these are outdated and rarely used nowadays. Any comments appreciated.

An open end wrench should work fine.

When you buy a set of sockets.....you'll sometimes see two of the 8 point sockets at the low end. Snap On sets all came like that. I have 8 point sockets in all three drive sizes.

Yeah, I'm thinking that a hardware guy who has never seen a square head lag bolt should probably be working at one of the big box's instead. I can't recall for sure, but would almost be willing to bet that 30-40 years ago, before certain power tools became prevalent, it was the other way around; you only found square head ones. Today, I have ocassionally had to dig a bit deeper or search a bit farther to find the right size square head lag for the sake of maintaining an element of authenticity. Nevertheless, the guy should have known. I dont know how many lags you have to drive, but you may spend more time and as much money buying the right sockets as you would to simply buy new hex head bolts. Hal, thank you for the reminder. I have a wrench very much like that in one of my tool boxes, and have used an open end or adjustable wrenches on square head lags for so long that I may have forgotten what it was originally used for.

Hardware guys who've never seen a square-head lag bolt?

I have driven square head bolts with a 12 point socket many times. Fit is a little sloppy, sometimes a metric will give a better fit.

I wonder of one of those multi fit sockets would work? GATOR-GRIP Universal Socket | The Official AsSeenOnTV.com™ Shop
I wouldn't pay $20 but I think I've seen them much cheaper.
