I'm looking for a bolt that has no threads at the end , the shank is slightly smaller than the threaded portion at the end.
Do they make such a thing ? What is it called ? I've searched clevis bolt, aircraft bolt , reverse shoulder bolt , I'm out of ideas as to the name. Any suggestions ? where can I find them. About a 10-32 or slightly larger. I'm going to need several hundred , so making them isn't feasible. |

Close but I need one with a head , preferably a hex cap screw style
I need the pin portion to pass through the hole and tighten down like a regular bolt , with the pin engaging a stop on the other side. It's on a sliding part of a machine , the pin acts as a stop. |

What is the application?
A bolt of this type is only useful in applications where it's used as a tensioner and can't pick up shear loads. If you're convinced this is what you need, you'll have to get one fabricated. You might luck out if the untheaded shank can be made by turning the threads off of a bolt that starts out threaded full length. I read the second post; that helps. I still think you'll have to get the bolt fabricated, but you can probably start with a conventional bolt, just remove the threads on the end. (I originally pictured a bolt with an unthreaded shank between the head and threads.) |
| Just use a longer bolt. If extra threads won't catch on anything, it should still work as a stop(unless you are worried about disassembly later). I have seen bolts such as you describe; but never that small, only in special applications, and I have no idea what they are called. |

Looks like I'll be turning down my own on the lathe
$3.78 ea. 
I realize it's a specialty screw but COME ON! Looks like I could make about $150.00 per hour makin these things. standard screw , my cost $0.12 I can turn down 35- 45 per hour $3.66 X 40 = $146.40 per hour
ANYBODY want to buy some full dog point screws ? ? HALF PRICE
