Accud
Accud Long Feeler Gauge — 150mm, 20-Blade, 0.05–1.00mm
Part No: AC-913-100-20 | Barcode: 9346967026754 | Series: Accud 913/914/915 Long Feeler Gauges
The Accud AC-913-100-20 is a 150mm long feeler gauge with 20 stainless-steel blades spanning 0.05mm to 1.00mm in 0.05mm steps. Built to DIN2275 with etched blade markings that won’t wear off, it’s the reference tool for gap measurement in valve clearances, spark plugs, bearing fits and machine setup.

Key Features & Benefits
- 20 blades from 0.05 to 1.00mm — half the steps of a 10-blade set, giving you the right blade for tighter specification calls without stacking.
- 150mm long blades — reach deep into valve-cover gaps, clutch fits and machine slides where short 100mm blades won’t reach the contact surface.
- DIN2275 accuracy — ±(3+T/80)µm per blade; certified to German precision standard for repeatable clearance measurement.
- Stainless-steel construction — resists oil and coolant corrosion in engine and machine environments; cleaner in use than carbon-steel blades.
- Etched blade markings — thickness stamped into each blade; won’t wipe off in solvent like printed markings.
- Clamping pivot screw — isolate a single blade and fold the others away when working in a tight space.
When to Use the AC-913-100-20
Reach for the AC-913 when you need to measure a clearance or gap to manufacturer spec — valve lash, spark-plug gap, bearing side-clearance, piston-ring end-gap, machine slide-way fits, or dial-indicator probe setup. For deeper gaps beyond 150mm, the AC-914 (200mm) and AC-915 (300mm) long feeler gauges in the same series have the same blade count and precision.
Pro Tip: The right blade slides into the gap with a light drag — not loose, not forced. If it won’t enter, step down one blade and try again; if it slides freely with no drag, step up. Stacking two blades (e.g. 0.10mm + 0.15mm to make 0.25mm) is acceptable when the exact blade isn’t in the set, but one blade is always more reliable than a stack.
