View Full Version : Short-Head Bolts
05-30-2005, 06:28 PM
I don't know what they're called but I need some bolts that have a shorter head. A normal 5/8" bolt will have about a 1/2" thick hex head. I need bolts with about 1/4" thick head.
Is there a special name for these? Are they a stock item?

You know, if there were only some type of machine available, that could somehow remove metal from a part...
Seriously, I needed some "thin" bolt heads to fit into a slot. I just faced down some standard 1/2" bolts- they were G8 but I just used a carbide insert. Is there some reason you can't do this? (Like you need a couple hundred, or the bolt has to retain it's grade markings?)

Yeah, I know Doc. If it were just a few, I'd face 'em down too. Seing as how I may need a gross, I don't want to be spending that much time in front of the lathe. Too many other things to get done right now.

Elevator Bolts have a carriage end and thin flat heads
I would probably just give ARP a call. I would think that they could fix you right up.
Sure sounds like an easy lathe job though. http://bbs.homeshopmachinist.net//biggrin.gif

Check with your nearest Caterpillar dealer. They use a few short-head capscrews. Last time I rebuilt a Cat engine, there were a few 3/8 N.C. by about a inch or so, held the spacer plate, between the block and front cover. Had the Cat logo, and the grade marks for everyone to see. Probably have assorted other sizes, also.
By the way, all Cat fasteners are grade 8 or better, and often times priced below the competition. Beware of hardware with markings showing grade, but no manufacturer markings.
Best of luck, regards, Tim

chuck threm up and cut off what you don't need.
Aircraft bolts have very thin, dished heads. I see these frequently at Boeing Surplus. The ones I've looked at were only fine thread type.
Not sure if these bolts are available to the general public (or if the price would even be reasonable).
Actually, Boeing doesn't really "sell" these bolts. But, some get mixed in with other surplus items occasionally. A few years ago there was a criminal case about some individuals buying reject bolts through the surplus center and reselling them to Boeing as good bolts. I understand those individuals got to spend some quality time at a federal instituion.

Back when I was building metal stamping tools
we used socket head cap screws called
"Low Heads". If you do a Google search on
that you'll get results.
