What is the standard american thread size for a pole handle? What is the tap size for the mating part?
21 mm pole size.Steel pole with a plastic thread end.
From experience I notice a pole handle thread is very similar to an acme thread. It may be a standard pole thread. To measure a thread measure the following:
The major diameter
minor diameter
effective diameter
pitch
lead
form
no of starts
handing (RH or LH)
prsuure angle
Look up referenece book or online for standard threads and compare.
It is possible ther eis a special thread just for the industry of ppole manufacturers
Steve:
Ieuan is correct. The thread on a 21mm pole is a standard acme thread. It is a 0.750 ACME-2G x 1.00″ long.
