The Sealey AK9634M Dial Gauge is a precision measuring tool for checking small linear movement and deflection in automotive and general engineering tasks. It provides an 8 mm measuring range in metric, displayed on a clear 42 mm diameter dial with a rotating bezel for quick zeroing. Built with a durable metal case and a smooth steel plunger, it delivers consistent, repeatable readings. The high-contrast dial is easy to read at a glance, and its compact form suits tight access areas around engines, transmissions, hubs, and machine setups. Commonly used with a magnetic base or stand, it is suitable for technicians, machinists, and DIY users who need accurate comparison measurements on vehicles, lathes, milling machines, fixtures, and inspection benches.

Key Features:
– 8 mm metric measuring range for accurate deflection and run-out checks
– 42 mm diameter dial with rotating bezel for fast zero setting and relative measurements
– Clear, high-contrast scale for easy reading in the workshop
– Smooth spring-return plunger for consistent, repeatable movement
– Robust metal body and steel contact point for durability in daily use
– Compact size for use in confined spaces on vehicles and machines
– Metric-only scale to match common UK workshop measuring systems
– Compatible with standard magnetic bases, holders, and clamps for hands-free setup
– Suitable for comparative measurements on jigs, fixtures, and inspection tasks
– Reliable Sealey quality for professional and home workshop environments

Typical Applications:
Checking brake disc run-out, hub and bearing play, crankshaft end-float, cam and valve train movement, and gearboshaft alignment. Useful for tramming a milling machine, setting a lathe tool or workpiece, straightness and flatness checks on surface plates, and general alignment and inspection tasks where small linear movement must be measured precisely.

Also known as:
Clock gauge, run-out clock, plunger clock, comparator gauge, machinist’s clock, precision clock gauge, metric dial gauge, measuring clock, run-out indicator, plunger indicator.
