Product FAQ's

1. What is a Hexagon Plug Gauge?

A Hexagon Plug Gauge is a precision inspection tool used to check internal hexagonal bores. It verifies dimensional accuracy, form, and tolerance compliance of hex sockets. These gauges ensure conformity to engineering standards and maintain strict quality control in manufacturing.

2. What types of Hexagon Plug Gauges are available?

Hexagon Plug Gauges are available in GO and NO GO types based on the limit gauging principle. The GO gauge checks maximum material condition, while the NO GO gauge verifies minimum material condition, ensuring accurate pass/fail inspection of internal hex profiles.

3. What size range is available for Hexagon Plug Gauges?

Hexagon Plug Gauges are available in sizes ranging from 1.5 mm to 36 mm in metric measurements and 1/16″ to 1-1/2″ in inch measurements. Custom sizes can also be provided as per specific requirements.

4. What tolerance accuracy do Hexagon Plug Gauges provide?

Hexagon Plug Gauges provide tolerance accuracy as per h6 and H7 standards, depending on customer requirements. These gauges are manufactured to ensure precise dimensional control and reliable checking of hexagonal internal profiles in industrial applications.

5. What materials are used in manufacturing Hexagon Plug Gauges?

Hexagon Plug Gauges are manufactured using hardened tool steel. These materials provide excellent wear resistance, dimensional stability, corrosion resistance (in stainless variants), and long operational life.

6. What is the hardness level of Hexagon Plug Gauges?

Hexagon Plug Gauges are typically hardened to 58–62 HRC. This hardness level ensures superior wear resistance, prevents deformation, and maintains long-term dimensional accuracy during repeated inspection cycles.

7. What standards do Hexagon Plug Gauges follow?

Hexagon Plug Gauges comply with ANSI / ASME B107.17M and ANSI B18.3 standards for hex socket dimensions and inspection practices. These standards ensure accurate hex profile verification and international quality compliance.

8. How do Hexagon Plug Gauges work?

Hexagon Plug Gauges operate on the limit gauging principle. The GO end must fully enter the hex bore, confirming minimum size compliance. The NO GO end should not enter beyond the specified limit, ensuring dimensional control and quick inspection.

9. Which industries commonly use Hexagon Plug Gauges?

Hexagon Plug Gauges are widely used in automotive, aerospace, heavy engineering, tooling, and fastener manufacturing industries. They are essential for inspecting hex socket screws, precision components, and mechanical assemblies requiring strict dimensional accuracy.
