Thread gauge Gimex model 318.003 — metric thread reference (MWGc METR/CAL)

The Gimex thread gauge model 318.003 — metric thread reference (MWGc METR/CAL) is a compact handheld tool designed for identifying and checking metric screw threads. It offers a physical reference of thread profiles and pitches to determine whether threaded fasteners and components conform to expected dimensions. The gauge is intended for on-site inspection in workshops, maintenance tasks and quality control processes where quick verification of metric thread types is needed.

Advantages

The device provides a simple, durable and easy-to-read way to match external and internal metric threads without relying on electronic equipment. Its compact form factor allows convenient storage in toolboxes and portability between workstations. Physical contact measurement reduces ambiguity when comparing thread pitch and profile, helping technicians to rapidly confirm compatibility and avoid mismatches during assembly or repair.

Suitable for

• Workshop thread identification and verification
• Maintenance and repair operations requiring fastener matching
• Incoming inspection and quality control of threaded parts
• Field checks where portable, non-electronic tools are preferable

Key specifications

• Type: metric thread reference gauge
• Function: identifies and checks thread pitch and profile
• Form factor: compact handheld physical gauge
• Material: durable metal construction suitable for workshop use
• Applications: external and internal metric threads on screws, bolts and nuts

How to use

Align the appropriate thread section of the gauge with the fastener to be checked and engage the thread profile gently. Rotate the fastener or the gauge to confirm smooth engagement without play or binding; a correct match will seat the threads consistently along their engagement length. For internal threads, insert the corresponding gauge profile and verify fit in the same manner. Perform visual inspection for wear or damage on both gauge and tested part before relying on the result.

Usage recommendations

Store the gauge in a dry, clean place and keep it free from burrs, corrosion or deformation to maintain measurement reliability. Use the gauge as a quick reference alongside calibrated measurement tools when high-accuracy verification is required. Replace the gauge if profiles become worn or damaged to avoid incorrect identification.
