JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, specifically calibrated for M26 x 1 holes. Its Go/No-Go design lets you quickly verify hole acceptance and prevent mismatches, making it ideal for engineers, machinists, quality teams, and hobbyists. The hardened steel body and knurled grip deliver durable, long-lasting performance in busy shops.

• Go/No-Go Quick QC: Quickly verify hole acceptance with a simple pass/fail check, reducing inspection time and keeping production moving.
• Metric Fine Thread Mastery (M26 x 1, Right-Hand, 6G): Precisely calibrated for metric fine threads, specifically M26 x 1, to ensure reliable fits in tight-tolerance assemblies and standard right-handed installations.
• Durable Hardened Steel with Knurled Grip: Built to endure daily workshop use, the hardened steel resists wear while the textured grip provides secure handling even when wearing gloves.

This plug gauge helps you streamline threading inspections, reduce guesswork, and ensure consistent fits across assemblies. By delivering clear pass/fail results and durable performance, it supports faster setups, fewer reworks, and higher confidence in every threaded connection.
