This listing is for 100 pcs.. (weight is 12.8 oz)
Antenna Factory surplus, I have almost 10,000 of these. They are 3/4" diameter with an outside knurl. See the drawing image. They are 0.9" thick, easy for the fingers to fasten without any tools. High quality which passed our factory specifications for quality.
The threads are for use with F-type female connectors, or any other 3/8-32 item. Switches, pots etc.. There is 1 picture showing how we used it under an antenna for Zboost many years ago.
Resellers welcome. Please ask about 1000 and 5,000 lots. Its a unique item I custom designed, and you cant find these anywhere else.
No returns, surplus sale below cost.
