Milisten 3pcs Bass Guitar Strap Button Pickup Copper Endpin Jack for Guitar Guitar Accessory Gold GT310

Was so excited to get these but so disappointed that the threads do not match the standard threads for audio jacks. I have K& K pure minis installed on two guitars and these will not thread down to cover the nut. Can only get it to catch the end.

I would have done well to read the other review, but who would have thought the thread could have been different to the other twelve or so end pin jacks I have in my workshop, but it is...Give them a miss guys...
