Has a slide pin (working) in the ball retainer, has a spring-pin (working firmly) in the 3/4 (male) end. Female end is 1 inch. Good quality unit in good physical condition overall.
I have some other 3/4 drive sockets listed, so feel free to buy multiple, I can fit several sockets together without increasing postage, up to 5 kg.
Buyers Note: Vintage sockets may have burred jaws, rust, pitting, engravings, scratches, chipped chrome and general wear and tear. Please inspect photos before buying.
If buying multiple items, add them to your cart and go to checkout, and use the 'request invoice' button before paying, and I will do what I can to minimise postage.
