The Mefape Pin Gage Set is a workshop-grade collection of precision pins for checking hole sizes and fitments, with clearly marked sizes and tight tolerances. Using the set brings confidence when verifying small bores and dowel fits in production and repair work. Is the 190-piece range the right coverage for your inspection needs?
⚡ At a Glance
- • Measurement Accuracy: Tight dimensional control suited to sub-thousandth inch checks
- • Best for: Inspection benches, precision workshops and machinists verifying small bores
- • Not ideal for: Coarse DIY or general hand-tool tasks where fine tolerances are unnecessary
A 190-piece British-standard set covering 0.061" to 0.250" with each pin 2 inches long. Electro-etched sizes, Class ZZ tolerance and HRC 60-62 hardness focus the set on repeatable precision and durability.
Quick Identification - thanks to electro-etched size markings
Each pin is permanently electro-etched with its size on the shank, eliminating worn or loose labels. The marking method resists abrasion so numbers remain legible through regular handling.
Fast selection reduces inspection time and lowers the risk of using the wrong gauge during repetitive checks.
Predictable Fits - with Class ZZ tolerance (0.0000" to -0.0002")
Class ZZ specifies diameters from nominal down to minus 0.0002 inches, keeping manufacturing and inspection limits tightly controlled. The narrow tolerance range makes comparative measurements reliable across the set.
Consistent diameters help confirm whether bores meet tight specifications, useful for quality control and precision assembly.
Long-Wearing Construction - thanks to HRC 60-62 hardness and anti-corrosion treatment
Heat treatment to HRC 60-62 increases surface hardness, while anti-corrosion finishing reduces oxidation and surface degradation. A smooth finish and round chamfer reduce edge damage during insertion.
Durable pins retain their shapes through repeated use, so measurement integrity holds up in busy workshop environments.
✨ The 4 Key Reasons for Mefape Pin Gage Set
- Electro-etched markings - Read sizes instantly without removing pins from the rack
- Class ZZ tolerance - Maximum deviation limited to 0.0002 inches for repeatable results
- HRC 60-62 hardness - Resists wear that could change diameters over time
- Round chamfer and smooth finish - Easier, safer insertion into bores and reduced burr contact
