Screw(Bolts) Reduce?

In electronics, we use something called a stacking standoff that might work. A stacking standoff is either round or hex stock with one end turned down and threaded and the other end drilled and tapped.

Threads of 4-40, 6-32 and I believe 8-32 are common with of-the-shelf lengths up to about an inch in 1/16's increments.

Do not know if you can get them off the shelf but a reasonable fitter/machinist could make them to order.

I have had a couple of sets made to fit wrong length (Cheaper) gas struts to hatchback doors.

As one poster mentioned, there are standoffs you can get but you didn't say what size you wanted. For something from 1/4" on up to around 3/4" you may want to consider making some up from some threaded rod and couplers. These can be found at the borgs or most hardware stores. For your application, cut a section of the threaded rod (same size and tpi as the coupler) and screw it about half way in. You may want to peen the end of the coupler or add some Locktite on the threaded rod section to make it more or less permanent. For the other end, use the bolt that also has the same size and tpi (i.e. 1/4"x20).

You can buy internally threaded rod connectors and use a piece of all thread. Then just tack weld them to make one piece.

As others have said, that's a standoff. Log to:

Resolve the material and size available from the resulting dialogs.

Thanks to all who responded.

I need 1.5cm length at narrow end, and at the broader end length needs to be upto 4cm long.

I need to bridge the gap of 4.5cm between bolt and nut where alignment has to be absolutely perfect.

Not being able to locate responses I have posted a mail today which may please be ignored.

Btw..this is the sort of stuff turret or capstan lathes are a joy to own for.

Thank you very much Winston.

I've never seen a standard hardware item like this, but perhaps you could use a "coupling nut" and a piece of allthread?

Sure..balloon making, and sex.

Though..it does depend on if you are Jarno or Morse tapered.

Thanks.

Keep in mind though that a fastner that has a sharp transition from one size to another creates a stress area at that point. If the application is not very light duty, you have a huge chance of it snapping where the transition takes place.

Bah, fit a crank on it. Or build a steam engine with it. :-))
