Accud
Accud Long Feeler Gauge — 300mm, 20-Blade, 0.05–1.00mm
Part No: AC-915-100-20 | Barcode: 9346967026778 | Series: Accud 913/914/915 Long Feeler Gauges
The Accud AC-915-100-20 is a 300mm 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, the 300mm length reaches deep into deep machine gaps — large industrial engines, diesel blocks, heavy machinery slide-ways where standard-length gauges can’t span to the contact.

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 spec calls without stacking.
- 300mm long blades — deep reach into deep machine gaps — large industrial engines, diesel blocks, heavy machinery slide-ways where standard-length gauges can’t span to the contact; where shorter blades can’t touch the contact surface this length gets you there cleanly.
- DIN2275 accuracy — ±(3+T/80)µm per blade; certified to the German precision standard for repeatable clearance measurement.
- Stainless-steel construction — resists oil and coolant corrosion in engine and machine environments.
- Etched blade markings — thickness stamped into each blade; won’t wipe off in solvent.
- Clamping pivot screw — isolate a single blade and fold the others away when working in a confined space.
When to Use the AC-915-100-20
Reach for the AC-915-100-20 when standard 300mm feeler gauge is what the job calls for — valve clearance on larger engines, machine slide-way fits where the gap sits deep inside the machine, or precision spindle setup where shorter blades can’t span to the contact faces. For shallower gaps see the AC-913 (150mm); for deeper still, the AC-915 (300mm).
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 is acceptable when the exact size isn’t in the set, but one blade is always more reliable than a stack.
