Precision Plug & Pin Gage Set - Industrial Measurement Tools

1. Multi-Purpose Inspection Tool
Quickly checks hole sizes (0.061"-0.250"), slot widths, keyways, and V-groove alignment. Perfect for verifying drill/chuck runout, dovetail slots, and calibrating calipers or micrometers.

2. Simple Go/No-Go Testing
Go-End (0.2500"-0.2502") should slide in easily - if not, hole is too small (can be reworked)
No-Go-End (0.2548"-0.2550") must not enter - if it does, hole is too large (scrap part)

3. Heavy-Duty Workshop Construction
Made of hardened bearing steel (60-62 HRC) with ultra-smooth finish (≤10μm) for consistent, repeatable measurements that stand up to tough shop conditions.

4. Precision Engineering
Maintains tight ±0.0002" tolerances and ±0.01" stability across the full 2" measuring length. Laser-etched sizes stay visible even with heavy use.

5. Smart Storage & Protection
Foam-lined aluminum case keeps gauges organized and prevents damage - always ready when needed.

6. For Machinists & QC Inspectors
Essential for checking hole position, gear grooves, milling cutter alignment, and verifying part wear patterns in production environments.

Note: For best results, clean parts and gauges before use. Measurements should be taken at standard room temperature (68°F/20°C).
