Accusize Industrial Tools 0.011 to 0.060 in 50 Pc Pin Gage Set

In this review the Accusize Industrial Tools 0.011 to 0.060 in 50 Pc Steel Plug Pin Gage Set is assessed for small-shop machinists and inspection techs who need tight, repeatable measurements. The single biggest reason to buy is its Class ZZ tolerance, which delivers a consistent minus set range from 0.0000 in to -0.0002 in across fifty sizes, making the set useful for precise fits and routine inspection tasks. It is a compact, clearly marked collection of centerless lapped pins that feels more like a measurement kit designed for practical shop use than a household tool.

Key Features

• Electro-etched sizing: Each pin is marked with its actual size so users can quickly identify and select the correct gauge without guessing.
• Class ZZ precision: Tight tolerances of +0.0000 in / -0.0002 in ensure reliable minus-set checking for critical clearance and fit work.
• Durable hardness: Heat treated to about HRC 60-62 so the pins resist wear and maintain accuracy over repeated use.
• Consistent finish: Centerless lapped surfaces with a 10 microfinish or better provide smooth contact and predictable measurement feel.
• Uniform length: All members are 2 in long for consistent handling and easier insertion into fixtures or workpieces of similar setups.
• Practical range and count: The 0.011 in to 0.060 in span with 50 pieces covers fine incremental sizes useful for engine work, pin fits, and hobby machining.

Who It's For

The set is aimed at hobby machinists, small machine shops, quality technicians, and inspection benches that require a compact, accurate collection of plug pin gages for verifying hole sizes and clearances. Its clear size marking and Class ZZ tolerances make it suitable for users who need dependable, repeatable checks without high-end custom gages.

Those who should look elsewhere include users needing go/no-go master sets, calibrated certified standards for laboratory accreditation, or larger diameter ranges outside 0.011 in to 0.060 in. If you require traceable calibration certificates with each pin, a calibrated gauge set from a certified supplier would be a better choice.

Pros & Cons

Pros

• High size accuracy with Class ZZ tolerance for reliable minus-set measurement.
• Clear electro-etched markings make selection fast and reduce errors.
• Sturdy heat-treated construction (HRC 60-62) offers long-term wear resistance.
• Compact 50-piece range gives good incremental coverage for small holes.

Cons

• Not supplied with individual calibration certificates, so labs requiring traceable documentation will need additional calibration.
• The range is limited to 0.011 in-0.060 in and may not cover larger shop needs.

Specifications

Our Verdict

The Accusize 0.011 in to 0.060 in 50 Pc pin gage set is a practical, good-value tool for home machine shops and small quality departments that need accurate Class ZZ pin gauges without paying for high-end certification. It combines clear marking, durable heat treatment, and a useful size spread, making it a sensible purchase for routine inspection and fit checking - just not suited for labs requiring traceable calibration documentation.

Frequently Asked Questions

Are sizes easy to read?
Yes. Each pin is electro-etched with its size for quick identification during use.

Do the gages come calibrated?
The set is manufactured to Class ZZ tolerances but does not include individual calibration certificates; calibration must be arranged separately if required.

What is the material hardness?
The pins are heat treated to approximately HRC 60-62 for wear resistance and long service life.
