Measuring Wedge Selection — Quick Reference
Measuring wedges (taper wedges / wedge gauges) — GRADUATED WEDGE shape for measuring CRACK + GAP + SLOT widths at depth. Workshop + structural inspection + machinery + concrete + automotive. Different from feeler gauge (parallel) — wedge gives WIDTH AT DEPTH.
| Measuring Wedge Type | Best For |
|---|---|
| Standard Wedge Gauge | Workshop gap measurement |
| Bridge / Crack Gauge | Crack width measurement |
| Metric / Imperial Graduated | Match standard |
| Stainless Steel | Workshop standard |
| Small (0-15mm) | Fine gap measurement |
| Larger (0-50mm+) | Wide gap measurement |
| Combined with Feeler Gauge | Workshop versatility |
Critical: Compare to TAPER GAUGE — see taper gauges. Use FEELER GAUGE for parallel gap. Verify CALIBRATION periodically. Companion: taper gauges, measuring tools, feeler gauge guide, telescopic gauges.
Measuring wedges are tapered, graduated gauges that slide into a gap or crack until they stop — the reading at the surface gives the gap width directly. They're a workshop-floor inspection standard for measuring slot widths, weld root gaps, structural cracks and any opening too wide for a feeler gauge.
Where they fit
- Welding inspection — root gap measurement before tacking and welding.
- Structural inspection — crack width tracking on concrete, steel and masonry.
- Machinery condition monitoring — gap and clearance measurement on bearings, gears and couplings.
- Site work where a digital tool is impractical and a fast, reliable mechanical reading is needed.
Read at the surface of the work, hold the wedge perpendicular to the gap, and use the wedge under its own weight — never force it.
