Spurtar Feeler Gauges (0.03–1.00mm / 0.001–0.04") – 32 tapered blades, dual metric & SAE
Product description
The essentials
If you need to measure small clearances day to day, feeler gauges are one of those tools that make life simpler. The Spurtar Feeler Gauges cover a range from 0.03mm to 1.00mm (0.001inch to 0.04inch) and come with 32 tapered blades. The blades are dual marked so you can read either metric or SAE-style thickness without doing mental conversions.
On paper, this is built for practical use rather than fancy workshop displays: the numbers on each blade are etched for easier identification, the measuring edges are steel and polished, and the gauges are designed to fold away into a plated steel case with a thumbscrew. That last bit matters more than people expect, because a feeler gauge set you can actually store safely is a set you’ll reach for.
What it’s for (and where it fits)
This kind of feeler gauge is meant for checking gap thickness or width in places like spark plug fitment, valve gaps, piston-related clearances, and even guitar setups (as the description suggests). In other words, it’s the sort of tool you use when “roughly” isn’t good enough.
A simple example: if you’re checking a valve clearance, you’d take the blade that looks closest to the expected gap and test how it slides—too tight means the blade is too thick, too loose means you need a thinner one. With tapered blades, you can also find the transition more gradually, which can help when you’re chasing small changes.
Where it stands out
The most convincing parts here are the details that reduce friction during use:
- Dual marked metric and imperial blades for quicker identification
- Etched size numbers, so you’re less likely to mix up blades mid-job
- Polished steel measuring edges that are smooth and designed not to hurt your hand
- Tapered blades, which help with more controlled gap checking
What you should consider before buying
This set covers a specific range (0.03mm–1.00mm / 0.001–0.04"), which is great if your typical work sits inside it. But if your projects regularly demand measurements outside that bracket, you may find yourself wishing you had a larger or different range set.
Also, while the description mentions hardened, polished manganese steel and oil coating for rust protection, it’s still a precision tool. If you store it carelessly after use, moisture and dirt can still get in. It’s not perfect, but it’s clearly aiming to be practical and reasonably low-maintenance for everyday garage or workshop use.
How it’s built for day-to-day handling
The description calls out a few manufacturing choices that influence real-world feel:
- The steel edge is polished and set up to be smooth to handle
- The blades are made of flexible #65 manganese steel and are hardened and polished
- The blades are coated with oil to help resist rust and make the case easier to open
The foldable design is particularly useful if space is limited. Instead of blades lying around, you get a plated steel case and a thumbscrew to keep the set together.
Quick comparison in approach
In most tool ranges, you’ll usually choose between compact feeler gauge sets meant for common checks, and more specialised or broader-range kits for heavier calibration work. This one leans toward the “common clearances” side: enough blades (32) to cover the stated range, dual markings to avoid conversion steps, and a storage case so you can keep it where you actually work.
If you’re shopping for something you’ll use for occasional gap checks and the odd guitar adjustment, it fits that kind of workflow. If you’re doing frequent, high-precision measuring where you need more extensive ranges or different blade styles, you might find other approaches better suited.
Is it worth it?
A solid pick if you want a portable feeler gauge set that’s easy to identify (etched numbers), dual marked (metric and imperial), and designed to be stored safely in a foldable, thumbscrew case. It makes sense if your projects include things like spark plug and valve clearance checks, and you also want the option of using it for guitar setup work.
It may not be a great match if your required measurement range routinely sits outside 0.03mm–1.00mm (0.001–0.04"). And if you’re the sort of user who expects a feeler gauge set to replace more specialised precision measuring tools, this is better viewed as a practical clearance-checking aid rather than a catch-all calibration solution.
Mini FAQ
Can I use these gauges with both metric and imperial readings?
Yes, the set is described as dual marked for metric and imperial (SAE) measurements, with blade sizes etched for identification.
What kind of tasks is this feeler gauge set suited to?
The description points to measuring gap thickness or width for spark plug, valve, and piston-related checks, plus guitar use.
Are the blades easy to identify when you’re working?
They’re described as having etched numbers into the blades for easier identification.
Will the set rust easily?
The blades are said to be coated with oil for protection against rust and to help keep them easy to open in storage.
Does it store easily?
Yes, the feeler gauges are designed to fold into a plated steel case with a thumbscrew for safer storage.
