Feeler Gauge Types We Stock
AIMS Industrial stocks feeler gauges from Stahlwille, Maxigear, Lang Tools and Mitutoyo, covering precision toolroom blade sets, general workshop strip sets, loose replacement blades and heavy-duty diesel valve adjustment sets. Not sure which one suits your job? Our Feeler Gauge Guide: Types, Uses & How to Use covers selection in detail.
Stahlwille precision blade sets
Stahlwille's German-made precision feeler gauges suit toolroom and calibration-sensitive work. Blades are tapered and housed in a nickel-plated case:
- 13-blade metric set, 0.05–1.00mm (SW11095/13) — the common engine, valve and bearing clearance range
- 20-blade metric set, 0.05–1.00mm (SW11095/20) — finer intermediate steps for precision work
- 26-blade imperial set, 0.0015–0.025" (SW11097/26) — for dual-system workshops and imported equipment
Maxigear steel feeler strip sets and loose blades
Maxigear steel feeler strip sets cover general workshop and maintenance use in 100mm, 150mm and 300mm lengths, in both metric and imperial calibrations, with 17 to 20 blades per set. Individual metric (0.03–0.9mm) and imperial (0.001–0.04") blades are also stocked loose — useful for replacing a single damaged blade or building a custom stack for a mid-range clearance without buying a whole new set.
Lang Tools heavy-duty valve adjustment sets
Lang Tools heavy-duty sets are built for valve adjustment on petrol and diesel engines. The general-purpose set uses interchangeable handle and blade configurations for reach into tight valve covers, while the Detroit Diesel-specific set carries individual blades sized 0.019"–0.058" for Series 50 and Series 60 engines — getting valve lash right on these directly affects fuel economy and emissions compliance.
Mitutoyo thickness/feeler gauge sets
Mitutoyo's Series 184 thickness/feeler gauge set (184-305S) is aimed at quality control, engineering and manufacturing use, available in 13-leaf (0.05–0.3mm), 20-leaf (0.05–1mm) and 28-leaf (0.05–0.15mm) configurations for finer coverage where inspection work demands it.
Using a Feeler Gauge
Select the blade closest to the suspected gap and slide it in — the correct blade has a light drag fit, neither loose nor forced. The "go/no-go" technique confirms a clearance is within tolerance: find the thickest blade that slides in and the thinnest that won't, and the true gap sits between the two. For in-between measurements, stack two blades and add their thicknesses. Never force a blade — it bends the leaf and throws off every reading after. Common applications include engine valve clearance, spark plug electrode gap, brake shoe-to-drum clearance, bearing endfloat, and machine setup checks such as squareness and parallelism.

Feeler Gauges — Frequently Asked Questions
What is a feeler gauge used for?
A feeler gauge is a set of thin metal blades of known thickness, used to check small clearances and gaps — common uses include engine valve clearance, spark plug electrode gap, brake shoe-to-drum clearance, bearing endfloat and machine setup checks.
How many blades are in a Stahlwille precision feeler gauge set?
AIMS stocks a 13-blade Stahlwille metric set (0.05–1.00mm) for common clearance measurements, and a 20-blade metric set (0.05–1.00mm) with finer intermediate steps for precision work.
What imperial feeler gauge set does AIMS stock?
AIMS stocks a Stahlwille 26-blade imperial set (0.0015–0.025"), suited to dual-system workshops and imported equipment specified in thousandths of an inch.
What length feeler gauge should I use?
Maxigear steel feeler strip sets are stocked in 100mm, 150mm and 300mm lengths. The 300mm length is preferred for deep or restricted access, such as between valve cover assemblies or under bearing caps.
What are Lang Tools feeler gauge sets used for?
Lang Tools heavy-duty sets are built for valve adjustment on petrol and diesel engines, including a set with blades specific to Detroit Diesel Series 50 and Series 60 engines.
What is the "go/no-go" technique?
It's the standard method for confirming a clearance is within tolerance: find the thickest blade that slides into the gap and the thinnest that won't. The true clearance sits between the two, without needing one exact-fit blade.
