Taper Pins

Hi - Ive got a part with some tapered holes in it, but ive got no pins. The big end of the hole is about 60 thou and its 1/2" long. Do I make them, buy them? What taper will they be? What material? Do they need loctiteing in? Hope you can help. Nigel

Hi, sounds to me that they are standard taper pins 1/16" dia, generally taper pins are in inches per foot but i would have to look it up its to many years ago to remeber !!! Chronos sell them for £3.60 per 10off

Imperial sized taper pins have a 1 in 48 taper, metric 1 in 50. EKP Supplies also sell them in small quantities.

It really does depend on what the part is from and where and when it was built. Because there's also a metric series of taper pins too. Machinery's Handbook lists the dimensions. But a good industrial tool supplier would also list the dimensions for the taper pin reamers. You might need to make up a imperial and metric pin to see what fits the best. They do need to fit almost as well as a male Morse taper needs to fit the female bore.

You can get clock pins from Meadows and Passmore Put m-p into google they come in steel or brass

No, don't use loctite. If they are a good fit they just need a light tap to hold them in place. Remember, you might want to dismantle it at some time in the future.

Russell;

I got a good supply of taper pins from Proops and found a matching reamer at a boot sale. They work so well I'm surprised they aren't used more often. I have turned up my own pins when I have 'over reamed' the hole and they work fine.
