Exactly what I needed. At the store they are like 3 dollars for 2. I got them like new for about 8 for 50, which was almost half the regular price.But that is why I took of one star there was actually only 46 in it. But I didn't actually need but about 15 right now so I am going keep it. And the ones in it are in great shape just the box was in rough shape and it was missing four. So I maybe would have listed one below like new.

Worked as expected with the common coarse 3/8-16 rods and bolts. Length is 1-3/4"--longer than those at Home Depot which are 1-1/8". Size matches up with 3/8" nuts and takes the same 5/8" wrench.I use them for joining 3/8" rods. Also for sockets in the wood legs of work tables for 3/8" leveling bolts. The greater length gives more leveling range. The same sockets installed in wood legs of work tables can be used for heavy duty 5" caster wheels (available from Amazon) that have threaded stems of 1.5", so I can roll my work tables around while heavily loaded.

A coupling is a coupling , right? As long as they are not rusted, they are good to buy. But... very often, here in Canada, couplings are forgoten, missing, back order, in the major big box stores.This is why it 's a good idea to put them for sale, in small quantities, at good price, on Amazon. Well done Hillman.
