Feeler Gauge Spring Steel – Soft Flex Spring Material (Made in USA)

Softer hit. Smoother feel.

Lucky Supply Feeler Gauge Spring Steel is used as an alternative spring material for tattoo machine building. Compared to traditional blue steel spring stock, this material offers more flexibility and “give,” resulting in a lighter, smoother machine response.

Ideal for artists and builders looking to fine-tune their machines for delicate work, soft shading, or graywash setups.

Built for control. Designed for feel.

Why Builders Use It

Not all springs should hit the same.

Feeler gauge steel allows you to:

• Soften machine impact
• Increase flexibility in your setup
• Achieve smoother shading performance
• Experiment with different machine responses

When blue steel hits too hard—this is your solution.

Performance Characteristics

• Feel: More flexible with increased “give”
• Hit: Lighter, smoother, less aggressive
• Response: Ideal for controlled, delicate work
• Use Case: Shaders, soft black & gray, fine tuning

Blue Steel vs. Feeler Gauge Steel

Feeler Gauge Steel

• Softer flex
• Smoother hit
• Easier to bend and shape
• Less fatigue resistance (may take a set over time)

Blue Steel Spring Stock

• Stiffer, more rigid
• Harder, more aggressive hit
• Higher durability
• Holds shape longer under stress

Builder Insight:

Use blue steel when you need power.

Use feeler gauge steel when you need finesse.

FAQ

Q: Is this used the same way as spring stock?

A: Yes. It is cut, shaped, and installed just like traditional spring stock.

Q: What’s the main difference from blue steel?

A: Feeler gauge steel is more flexible and produces a softer, smoother hit.

Q: Is it as durable as blue steel?

A: No. It has less fatigue resistance and may take a set over time.

Q: What is it best used for?

A: Shaders, soft black & gray work, and machines requiring a lighter hit.

Q: Where is this made?

A: This product is made in the USA.

Pro Tip:

Start with feeler gauge steel for softer setups, then switch to blue steel if you need more punch.
