Feeler Taper Guage
. Taper Gauge (Wedge) : The pointed, triangular component is used to measure the width of slots, gaps, and bore diameters. As you insert it into a gap, the markings indicate the exact width (up to 15mm).
. Linear Ruler : The vertical body functions as a standard metric ruler for general length measurements.
Sliding Depth Gauge
. The crossbar (the "T" shaped part) slides along the ruler to measure the depth of holes or recesses.
. Pocket Clip: Includes a clip for easy carry, similar to a pen.
 
Common Uses
. Welding : Checking root gaps and fit-up before welding.
. Machining : Measuring internal diameters of pipes or holes.
. Maintenance : Inspecting wear or clearance in mechanical assemblies.
