Beefy little universal that compliments my SK 1/4" impact socket sets. First quality tool with great coating, smooth movement, and robust pin. I got it for 21 bucks,...a great deal for a US made tool.
SK Tools 1/4" Dr. Ball Swivel U-Joint Socket Adapter 32990
This is A Quality USA made tool and a good value. This u-joint works great as long you have enough space around the fastener for it . Good tool to have just won't get into every small space were you need 1/4" drive due to it's dia.
