The Fowler Shockproof stainless steel dial caliper has dial graduations of 0.001" with 0.001" accuracy, shockproof anti-backlash control, a sliding jaw with a lock, and a covered rack. This caliper is used for measuring inside dimensions (ID), outside dimensions (OD), depth, and step. This product has a 1 year warranty offered by Fowler High Precision. If you experience any problem contact Fowler directly for warranty claims.
Shockproof spring anti-backlash control with a heavy-duty spring offers increased accuracy over standard gear configurations. Backlash is the amount of clearance between mated gear teeth in the caliper controls that prevents the gear teeth from jamming. It is undesirable to have much backlash due to the lack of precision offered by the increased amount of play between gears. Certain gear designs can minimize or eliminate backlash; spring anti-backlash systems use a spring to add a compressive force, thereby minimizing backlash.
This caliper has a knurled lock screw to hold the sliding jaw in position and help ensure a consistent measurement. A covered rack prevents dirt and debris from clogging the gear, and helps prevent measurement errors. A thumb-operated fine adjustment roller allows for one-handed use.
The caliper measures 0.10" per revolution of the dial. The dial has 0.001" graduations, and the beam has engraved 0.1" graduations. The hardened stainless steel components, including the beam, measuring surfaces, rack, gears, and depth rod, offer corrosion resistance, increased accuracy, and long life. Self-contained movement eliminates gear misalignment, while the dual pinion drive mechanism reduces wear on the rack and pinion. An adjustable dial enables setting zero. The hardened stainless steel is polished to a satin chrome finish, to help prevent glare. This caliper comes with a fitted case.
Dial calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise meas
