QNOX Internal hexagon tape measur

Product Description – Internal Hexagon Tape Measure

This internal hexagon tape measure is a specialized measuring tool designed for precision work on fasteners and recesses with hexagonal sockets. Unlike standard tape measures, it features a uniquely shaped end hook or blade profile that fits directly into internal hexagon holes (such as those found on socket head cap screws, hex bolts, or set screws). This allows users to accurately measure the depth, length, or alignment of hexagon recesses in mechanical assembly, maintenance, and quality inspection tasks.

Key features include:

• Hex-compatible tip – securely seats into internal hex sockets for stable measurement.

• High-visibility scale – clear metric and/or imperial markings for easy reading.

• Durable construction – wear-resistant blade and impact-absorbing case for workshop use.

• Lockable blade – holds position for depth measurement inside blind hex holes.

Ideal for engineers, mechanics, and toolmakers who need to quickly verify hex socket dimensions without separate gauges.
