Anyone who’s ever tried to tighten a bolt in tight spaces will appreciate this 21 piece Finger Grip Socket set. Place the appropriate socket size on your finger, reach into the space and tighten away. I do wonder how well this works seeing as you probably wouldn’t be able to get a ton of leverage just using your finger. For those with brittle bones, just be careful with how much force you apply against the bolt, I’d hate to see you break a bone in your finger.
