Bolts and Set Screws

[pmccarthy]

I wasted a couple of hours trying to buy 5/16 x 1 inch bolts. Couldn't get them anywhere. Everyone had that size in set screws. I wanted bolts, with some shank for good location and to avoid side wear in the hole. Eventually I went to Bolts and Fasteners company and was told that you can't get bolts in those small sizes anymore. People just buy set screws and don't know the difference. So that's what I had to do. The world is going to pot.

We in Sydney have a very Old company " Lee brothers " known as the ' nut house ' .

They always seem to have any bolt I need .

No problem for me, about three quarters of my equipment is still imperial measure, and I can still buy small diameter nuts and bolts with unthreaded shank.

 

For the uninitiated, a set screw has the thread all the way to the underside of the head, a bolt has an unthreaded portion left on the shank. The unthreaded portion is called "the grip length".

Bunnings Aerospace have them.

 Most automotive parts suppliers have small Champion packs of nuts and bolts on a rotating stand.

Bolt and Nut Australia still call them nuts and bolts.

I buy a few bolts and nuts from AIMS Industrial or Blackwoods, but Caterpillar are the best for high grade fasteners, and for giving you the fastener specifications.

But you do have to have the Caterpillar "One Safe Source" book for the bolt and nut part numbers. It's readily available online in PDF format.
