HeeHoo Unified Thread Plug Gauge, with Double End & Class 2B, UNC/UNF/UNEF/UNS Series, for Checking Internal Inch Thread Hole (1"-32 UN-2B)

Key features

• Precision You Can Trust: Ensure every internal thread is perfect. Our Class 2B tolerance gauges give you the confidence that your manufactured parts will mate correctly, reducing scrap and saving you time and money on every project.
• Foolproof Go/No-Go Operation: Simplify quality checks for anyone on your team. The "GO" end must screw in fully, while the "NO-GO" end must not, providing a clear, immediate pass/fail result for even the most complex threaded holes.
• Built for a Lifetime of Hard Use: Crafted from hardened GR15 bearing steel (58-65 HRC), these gauges resist wear and abrasion. The durable, clearly marked aluminum handles ensure a secure grip and easy identification for years to come.
• Custom-Tailor Your Toolkit, No Waste: Buy only what you need! Our wide range of individual gauges means you can build a custom collection perfect for your work, saving money and space instead of buying expensive, pre-packaged sets with sizes you'll never use.
• Flawless Assemblies & Productivity: Eliminate cross-threading, stuck fasteners, and part rejection. This essential tool helps maintain consistent quality control, ensuring your products assemble smoothly and perform reliably every single time.
