Unior
Unior is a Slovenian tool maker. Autotools stocks Unior 1/2 inch sockets, long bit sockets, TBI screwdrivers, a universal joint and a valve spring compressor socket.
Unior sockets are sold singly, so a missing or lost size is easy to add to your set. They suit workshops and home garages where tools need to last for years.
A 6-point socket grips the flats better and is the choice for a rusted bolt. A 12-point socket is handier in tight spots where the ratchet has little swing.
