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.

Drawbar Rings
These rings mount to a trailer and connect to the drawbar coupler or tow hook on a vehicle to create a towing connection. Maximum trailer weight is the total weight being towed. Vertical capacity (also known as tongue weight) represents the weight of the load on the drawbar ring.
Note: Capacity is reduced 25% in off-road use.
