Fowler Dial Caliper 520300121 Precision Tool with Knurled Lock

Description

Product Overview

The Fowler 520300121 dial caliper is engineered for professionals who demand exacting accuracy in every measurement. Constructed from hardened stainless‑steel, the tool resists wear and maintains its calibrated integrity over years of use. Its raised sliding surface protects the graduations from abrasion, while a covered rack shields the internal gearing from dust and debris. The large white dial displays 0.001″ black graduations and 0.02 mm red graduations, with one full revolution equating to 0.10″ (2 mm), providing clear, easy‑to‑read results.

Whether you are calibrating machine parts in a manufacturing plant, checking component tolerances in a laboratory, or performing DIY projects at home, the Fowler dial caliper offers the confidence of precise data. Its ergonomic knurled lock screw secures the sliding jaw, allowing one‑handed operation and hands‑free measurement holding, which is especially useful in tight or awkward spaces.
