What would you call these bolts? And where would I find them? They have a fixed washer, a square head, and square nuts. Looks like 7/8 inch diameter, hot dipped galvanized.

I’ve got eight and I’d like another eight.

Thanks

Are you sure it's a washer and not a flange head? (Not that it makes it easier to find.)

Galvanized square head bolts.

 

[PCustoms]

Looks like the type of bolts used in power line construction.

Probably cheaper to go buy 16 new hot dipped galvanized bolts

Galvanized square head bolts.

Most aren't flanged. Those look like they are flanged to me. I don't think it's a washer.

Probably someplace like Grainger or Fastenall ? I would say they are carriage bolts but carriage bolts usually have a square part to keep them from turning when you tighten them.

 

[PCustoms]

You sure they're 7/8 and not 5/8" diameter?

 

[johnre]

Do you care that they look the same or that the flange is captive?

Just buy hex bolts and washers and be done with it.

And if it appearance matters, do as @PCustoms suggests and buy 16.

And FWIW - by my eye, looking at the gap in the deck next to the 14" mark on the rule and comparing to the bolt shank diameter, I'd say 9/16". Definitely not 7/8".

Hubbell makes those square headed bolts and nuts. Linemen can't figure out a hex head!

Good guess but likely not long enough.

Yes Just shy of 1”

 

[bluedog225]

I was trying to match them for aesthetic reasons. I think they’re just old utility bolts. Maybe not made anymore. I checked out Hubble site but couldn’t find something with that integral washer. Not a big deal. thank you all.

I've seen the one piece washer bolts in old crates I would judge to be 1930s or 1940s, so probably won't find them anymore.

The one in the background doesn't have a flange. I'm guessing on most the washers are stuck under the head. Minor detail as far a asthetics.
These days hex heads will be easier to find but square heads are still made.

The ones in the back.
Looks like standard 5/8 x 12 utility pole bolts.

Didn't even see those back there....

I'd say the OP was clearly talking about the 8 in the front, but I count 9?

Lineman’s Lag Wrench

Our bolts were 5/8 and 3/4 , 8" to 18".
For anything needing longer we used D.A. bolts (Double Arming) "all thread"

Never in 40 years have I heard of a lineman lag wrench. 1/2" Lags (hard heads) are driven in to a pole, not screwed in. I guess it could be used for removal but there are better tools that have more functions available. I always just used a crescent wrench or channel locks.
The less tools on my belt the better.

 

[Jacko264]

If it was me I would get some 7/8 threaded rod and weld square nuts on the end , sand up and cut to the length bolts you want

[whateg01]

If the flange isn't important or a washer can be added, square head bolts can still be bought, as shown by the links above. I still think they look too have an integral flange from the draft angle on the square part and what appears to be a small fillet where it meets the flat.

I was issued a similar lag wrench but never used one. The telephone pole was drilled and then a cross arm was mounted with the hardware required. I have some of the old zinc bolts but that is pretty well an item of the past. Where we live everything is underground with the exception of the towns and cities that were aerially served previously by pole leads.

Off topic but are you referring to something like these?

Washer Head Bolts - Pole Line Fasteners

Washer head bolts are used when the head of the bolt sits flush to a wooden member. The forged washer side provides a larger bearing surface so that when the bolt is tightened, the wood underneath the head is not damaged. Washer head bolts have an added semi-cone point and a thread length unique...

The pic you posted is a J hook or Drive Hook.

Below is what we call a Hardhead. It's driven in with a BFH instead of screwed in like a regular lag bolt. This design is easier to drive and easier to remove.

If those bolts are 7/8" diameter, somebody stretched your tape measure.

Thanks for your input. The photographs can be misleading.
