Thread-In Receptacles for Quick-Release Pins
Use a screwdriver to install these receptacles in a threaded hole. Use them to secure quick-release pins when you can't drill a through hole. They're made of 18-8 stainless steel for a balance of strength and corrosion resistance, and passivated for added protection against corrosion and oxidation.

Threaded Plug Gauges with Calibration Certificate
These gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They allow you to inspect internal threads on parts. All have a go gauge on one end and a no-go gauge on the other end. A taperlock handle lets you quickly replace worn gauges.
Check the minimum internal thread size with the go gauge end, and check the maximum internal thread size with the no-go gauge end. A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.
Threads have different classes of fit. Thread fit designates the tightness or looseness of mating threads. For example, inch threads with a 3B fit have tighter tolerances than threads with a 2B fit.

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.
