Taper Gauge Selection — Quick Reference
Taper gauges — PRECISION measurement of TAPER + WEDGE + KEYWAY dimensions. Workshop + tool room + machining + metrology. Different from feeler gauge (parallel gap) — taper gauge is GRADUATED WEDGE shape that gives reading at depth of insertion.
| Taper Gauge Type | Best For |
|---|---|
| Standard Wedge Taper Gauge | Workshop gap + slot measurement |
| Bridge / Crack Gauge | Crack width measurement |
| Imperial / Metric Graduated | Match measurement standard |
| Stainless Steel | Workshop standard |
| Small (0-15mm) | Workshop fine measurement |
| Larger (0-50mm+) | Larger gap measurement |
| Calibration Certificate | QA + production work |
Critical: Match graduation precision to need. Verify CALIBRATION before critical use. Compare to FEELER GAUGE (parallel gap) — different tool for different measurement. Brands: C.H. Hanson. Companion: measuring tools, telescopic gauges, gage blocks, measuring wedges.
Taper gauges are tapered measuring tools that slide into a slot, gap or opening until they stop — the reading at the surface tells you the width. They're a fast, robust way to check slot widths in machinery, gaps in welded assemblies, openings in punched or cut sheet metal, and anywhere a feeler gauge isn't practical.
Common applications
- Checking gaps in welded joints before final pass.
- Measuring slot widths in keyways, parting cuts and milled features.
- Inspection of openings in fabricated sheet metal and structural assemblies.
- Bridge and structural steel gap measurement during installation and inspection.
Read at the surface of the work, not the leading edge of the gauge. Hold the gauge perpendicular to the slot axis for repeatable readings, and don't force it — a taper gauge slides under its own weight when correctly sized.
