Low-Strength Steel Coupling Nuts
Also known as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.
Zinc-plated steel coupling nuts resist corrosion in wet environments.

Rod Alignment Couplers
Increase cylinder life by fixing alignment problems between air or hydraulic cylinders and driven components. Couplers have a threaded end that moves to compensate for the angle of misalignment, reducing wear on cylinder bearings and seals. Couplers have a male and female end.

Hitch Balls
Mount these onto a hitch insert, and connect them to a trailer with a hitch-ball coupler. Maximum trailer weight is the total weight being towed.
