The Atisumeru limit screw plug gauge, essential for screw hole precision control.
In machine tool maintenance, DIY parts production, and inspection work, whether the screw hole standards match is extremely important.
This product was developed with the goal of maintaining specifications that satisfy professionals while remaining at a price point that is easy for individuals to adopt.
*Material pursuing wear resistance: GCR15 bearing steel, which combines hardness and toughness, is used for the measuring surface.
It suppresses wear even during repeated insertion and removal tests, leading to stable judgment results.
*Hexagonal grip to improve workability: A hexagonal handle is used, which is less likely to roll compared to round handles and provides a better grip.
The matte anti-slip finish supports measurement work where a precise sense of touch is required.
*Available size variations: Highly versatile M4 (0.7) and M6 (1.0) variations are available.
Please use it for checking after tap processing or for diagnosing wear in bolt holes.
[Specifications] - Precision: 6H (Metric screw) - Material: GCR15 bearing steel (Hardness 58-65HRC) - Content: 1 piece (Integrated Go/No-Go type)
[Adopts highly reliable GCR15 bearing steel] High-grade bearing steel "GCR15" with excellent wear resistance is used for the measuring head.
Strict surface heat treatment has been applied to achieve a hardness of 58-65HRC.
It is resistant to deformation even after long-term use and maintains stable measurement accuracy.

[High-precision screw thread processing] Adopts a 60-degree spiral tooth angle with a smooth finish free of burrs.
Through a precise grinding process, high-precision measurement has been made possible.
Ideal for factory inspections, prototype processing, and DIY screw thread checks.

[Intuitive Go/No-Go judgment] Double-ended design with "Go (T/通)" and "No-Go (Z/止)".
The quality of the screw hole can be judged instantly.
Includes highly visible engravings to prevent size mistakes at the work site.

[Easy-to-grip hexagonal handle] Adopts a hexagonal handle shape that fits comfortably in the hand.
Because it has an anti-slip finish, it can be held firmly even with oily hands, suppressing measurement blur.

[Cost performance that meets site needs] For everyone from professional use to hobby use who feels that "expensive measuring instruments are hard to afford, but I don't want to compromise on accuracy."
By pursuing practicality and eliminating middleman margins, cost performance has been achieved.
