Need help finding this rivet bolt

admin

I'm needing to match this bolt with a rivet style head on it. It's a 3/4" bolt. I've checked King Metals along with a few other places and no luck. If anyone has suggestions I appreciate it. Attached ImagesDynamic MetalworksMontrose, CODynMetalworks.com
Reply:It's called a "Carrage Bolt"http://www.grainger.com/product/21A9...140626201521:sThat's just one of them.Granger has all sizes.......zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Thanks for the reply, but these aren't carriage bolts. They are just like a normal bolt, not square hex to hold the head. The head looks like a rivet, that's the style of it. Kind of hard to tell from the picture.Dynamic MetalworksMontrose, CODynMetalworks.com

Reply:it looks like a heat treated a325 button head structural bolt to me. i have a few laying around and they have a knurled tit on the end so when the impact gun gets to the correct torque it wrings off.i.u.o.e. # 15queens, ny and sunny fla

Reply:Yep, TC bolt.  Beat me to it.  Not a carriage bolt.  The broken off end past the nut is a dead giveaway.

Reply:BryanDowdyA325s are not a general consumer bolt;even major distributors don't carry them.As illustrated, they require a hard-washer,and a heavy-hex [larger] nut.The driver snaps off the splined stub thrua circumferential valley at proper torque.Some of the larger steel suppliers carry them.  If your source doesn't, they should know who does.Drivers are in the 4K to 5K range, so you'llprobably end-up wrenching them.  Cut the splines off, if left on they look corny to the informed viewer.Opus
Reply:Originally Posted by Gerry1964Thats exactly what it is doc, In the UK they are called Shear boltsThe Shear Wrench which looks like thisThe inner part rotates one way and the outer part that holds the nut rotates the opposite way, the torque is unbelieveable i've seen 15mm plate bend as these bolts have been tightened up

Reply:BryanDowdy  -  AddendumMaterially: A325's are Grade 5  -  with a different yield-profile.In service, there are no substitutes. For looks on steel - carriage-bolts cannot compared to A325's.Carriage bolts only prevail when there is a wood interface.Opus.Last edited by OPUS FERRO; 06-27-2014 at 03:07 AM.Reason: i before e - except after c . . .
Reply:Try Fastenal, only problem is that they don't like to deal in small quantities.  I'd be surprised if they didn't have them though.

Reply:My local Fastenal does have A325 bolts in their mix and match bins, I doubt though that they would have the tension bolts. I usually have to order those from a supplier (we always called them Lejune bolts, I guess they make them)
