'afternoon.
The link following is to a picture of a brass shower and bath mixer with the handle of the hot water tap removed and turned upside down.
The axle of the tap mechanism is "serrated" and the tap handle socket is matched to accept it, however the fit is very loose and the handle is easily removed. Indeed it will often fall off.
There is no grub screw on the handle.
Banging on the handle to force it deeper onto the axle doesn't achieve anything, i.e. the axle and socket are fully engaged with a minimum effort.
Any ideas what this connection is actually called? I've been searching, but can't express the concept clearly enough... "brass tap connector" does not return useable results.
And how would one secure the handle? (I'm tempted to use some sealant I've got lying around, but I'd prefer a proper solution.)
Thanks & regards
