Tow Eyes

Style 4

These eyes mount to a trailer and connect to the drawbar coupler or tow hook on a vehicle to create a towing connection.

Note: Capacity is reduced 25% in off-road use.

Corrosion-Resistant-Coated Steel—Corrosion-resistant-coated steel eyes offer the most corrosion resistance.

For Maximum Trailer Weight—Maximum trailer weight is the total weight being towed.

Vertical Capacity—Vertical capacity (also known as tongue weight) represents the weight of the load on the tow eye.

Go/No-Go Threaded Plug Gauges with Handle

Speed up thread tolerance checks—the handle on these gauges gives you a good grip to quickly thread and unthread go or no-go gauges. Use these gauges to make sure nuts, tapped holes, and other parts fall within tolerance. All are precisely manufactured to confirm thread fit. If the plug gauges wear down, you can insert new ones (not included) onto the taperlock handle.

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.

Go/no-go gauges have both a go gauge on one end of the handle and a no-go gauge on the other to speed up tests. Go gauges check the minimum internal thread size. No-go gauges check the maximum internal thread size.

Accuracy Certificate Traceable to NIST—Gauges with an accuracy certificate traceable to NIST include verification from the manufacturer that their thread sizes are within tolerance. The certificate is also known as a certificate of compliance or a short-form certification.

Calibration Certificate Traceable to NIST—Gauges with a calibration certificate traceable to NIST were calibrated in a lab. The certificate, sometimes called a test report or long-form certificate, details the tested measurements.

For Class 2B Unified Standard Thread Fit—For inch threads, the higher the class number, the tighter the fit. Unified Standard Class 2B is standard and works for most applications.

For Class 3B Unified Standard Thread Fit—The tightest fit for inch-sized threads. Unified Standard Class 3B fits completely flush in applications where parts need to stay in place, such as engines and suspension systems.

For Thread Fit—Thread fit designates the tightness or looseness of mating threads.
