Caliper AWTools AW18812 — mechanical caliper, weight 1.63 kg, pack of 12

The AWTools AW18812 mechanical caliper is a robust hand tool designed for precise linear and diameter measurements in workshop and industrial environments. Supplied as a pack of 12 units, each caliper is manufactured from solid carbon steel with a rust-proof, blasted finish to resist corrosion and wear. The tool is calibrated for routine inspection and part verification tasks and is presented in a plastic case for convenient transport and organized storage.

Advantages

This mechanical caliper combines durable carbon steel construction and a corrosion-resistant surface for long service life under workshop conditions. Its mechanical design does not require batteries or electronics, ensuring reliable performance in varied environments. The compact form and included plastic case make handling, transport and storage straightforward when multiple units are needed for professional use.

• Type: mechanical caliper (manual, non-electronic)
• Weight per unit: 1.63 kg
• Packaging: pack of 12 units with individual plastic case for transport/storage
• Application: linear and diameter measurement for workshop and automotive use

How to use

Hold the caliper by the main beam and position the jaws around or against the object to be measured. For external dimensions, place the outside jaws on the part; for internal dimensions, use the inside jaws or appropriate measuring faces. Slide the movable jaw until it makes firm contact with the part, then read the measurement from the caliper scale. After use, clean any debris from the measuring faces and return the caliper to its plastic case to protect the rust-proof finish and maintain accuracy.

Usage recommendations

Store calipers in the provided plastic case when not in use and avoid prolonged exposure to moisture or corrosive chemicals despite the rust-proof finish. For consistent results, inspect jaws for wear before critical measurements and perform measurements on stable, clean surfaces. Use the set for general inspection and brake servicing tasks on most vehicle makes, following vehicle manufacturer guidance where applicable.
