Question 1

What is the Stanley STMT78212-8 0.04 to 1mm Combination Feeler Gauge, and what is it used for?

Accepted Answer

It's a 25-blade combination feeler gauge designed to measure small gaps and wear on both internal and external surfaces. With a range from 0.04 mm to 1.00 mm, it’s ideal for automotive, mechanical, and precision-machining setups where accurate gap measurements are needed.

Question 2

How many blades are included and what sizes are available in this gauge?

Accepted Answer

The set includes 25 blades in the following sizes: 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.60, 0.70, and 1.00 mm.

Question 3

What materials are used for the blades and the handle, and how does that affect durability and corrosion resistance?

Accepted Answer

The blades are carbon steel that are ground, hardened, and tempered for accuracy and longevity. They’re protected with rust-preventing oil to resist corrosion, and the handle is designed for a comfortable grip with a finger concave shape. The surface is bright zinc-plated for added corrosion resistance.

Question 4

Does this gauge provide imperial as well as metric measurements?

Accepted Answer

Yes. The gauge is designed for versatile use with metric measurements (millimeters) and accompanying imperial references to support both measurement systems.

Question 5

How do I use this gauge to measure a gap or clearance?

Accepted Answer

1) Clean the gap. 2) Select the blade that fits the gap with a light drag. 3) Insert the blade into the gap and apply gentle, even pressure. 4) Read the closest size that fits and note the measurement. The ergonomic handle makes one-handed operation easy.

Question 6

What are the best use cases for this feeler gauge?

Accepted Answer

Use it for automotive engine tolerances (valve clearances, bearing fits), machinery setup, precision engineering, collets and tool alignment, and general gap wear checking on both internal and external surfaces.

Question 7

How should I store and maintain the gauge to keep it accurate?

Accepted Answer

Store it in its protective pouch or a dedicated tool container to shield it from dirt and moisture. Use the hang hole to keep it accessible, and lightly oil blades after use to prevent rust. Wipe blades clean before returning to storage.

Question 8

Are there safety considerations I should keep in mind when using a feeler gauge?

Accepted Answer

Handle blades with care to avoid cuts or bending. Apply only light, even pressure when testing gaps to prevent deforming blades. Keep blades away from skin and children, and store safely after use.

Question 11

Why might this gauge be a smart value choice for my workshop?

Accepted Answer

It combines a durable drop-forged steel construction with corrosion resistance, a complete 0.04–1.00 mm range across 25 precise blades, and an ergonomic design for one-handed operation—delivering accuracy, longevity, and ease of use at a reasonable price.

Question 12

Is this gauge suitable for professional use as well as DIY projects?

Accepted Answer

Yes. The hardened and tempered carbon steel blades, along with the corrosion-resistant finish and ergonomic handle, make it reliable for professional machining, automotive work, and precise hobby projects alike.
