Review on 🔩 High-Quality USS Coarse Coupling Nuts 3/8"-16: Reliable Fasteners for Heavy-Duty Applications by Lawrence Crespo

Worked as expected with regular 3/8-16 coarse rods and screws. The length is 1-3/4" - longer than Home Depot's which are 1-1/8" long. Sized to fit 3/8" nuts and requires the same 5/8" wrench. I use them to connect 3/8" rods. Also for 3/8" jacking sockets in workbenches. A longer length gives a larger range of alignment. The same sockets found in the desktops wooden legs can be used for heavy duty 5" casters (available from Revain) with 1.5" threaded links so I can roll my desktops around when heavily loaded.
