00478MP Angle Meter Gauge Adaptor | ½″ Drive Magnet

FAQ Section

What is the purpose of the magnet on the 00478MP angle meter gauge?

Traditional angle gauges use a long, flexible metal arm that you have to manually hold against a solid part of the machine to keep the gauge housing from spinning while you turn the wrench. The Hans 00478MP features a powerful integrated magnetic base that locks the gauge shell firmly to the engine block or metal frame completely hands-free, preventing the dial from moving so your degree readings remain perfectly accurate.

Can I use this magnetic angle adapter with an air or electric impact wrench?

No. The 00478MP angle meter gauge is a high-precision testing instrument engineered exclusively for manual hand tools, such as ½”drive breaker bars, manual ratchets, and click-type mechanical torque wrenches. Utilizing percussive power tools will shatter the internal indexing mechanisms and crack the clear viewing face.

How do I reset the scale back to zero between different bolt stretching stages?

The tool is built with an adjustable zero-index face. After you have seated your bolt to its initial torque specification, you simply grasp the outer ring of the clear window and rotate it until the Zero degree mark aligns perfectly with the pointer needle. You are then ready to execute your precise degree-turn sequence without having to do complex math.
