Feeler Gauge Set GEKO 13-Blade 0.05–1.00 mm, thickness range 0.05–1 mm, 13 leaves

Feeler gauge set GEKO 13-Blade 0.05–1.00 mm is a compact tool kit for precise gap measurement in automotive and mechanical maintenance. The set contains 13 steel blades (leaves) that cover thicknesses from 0.05 mm up to 1.00 mm. Each blade is stamped with its thickness for quick identification and the blades are joined by a pivot screw that keeps the set together for safe handling and convenient storage.

Advantages

The steel blades provide consistent thickness and durability suitable for repeated use. Clear stamped markings on each leaf make selection fast and reduce measurement errors. The pivot screw construction allows individual blades to be deployed and locked at any angle while keeping the remaining leaves neatly folded. The compact format is easy to carry in a toolbox or service bag.

Suitable for

• Checking valve clearances on engines
• Setting and verifying spark plug gaps and ignition components
• Measuring clearances in bearings, shafts and couplings
• Machine setup and inspection tasks in workshops
• General gap measurement and calibration in mechanical assemblies

Key specifications

• Number of blades: 13
• Thickness range: 0.05 mm – 1.00 mm
• Material: hardened steel blades
• Marking: thickness value stamped on each blade
• Joining type: pivot screw for compact folding and safe storage

How to use

Select the blade corresponding to the required thickness by reading the stamped marking. Fold out the chosen leaf and insert it between the mating surfaces or into the gap to be measured. A properly sized blade should slide with a slight friction; if it fits too loosely or not at all, try the next thicker or thinner leaf until the correct fit is found. After use, fold the blade back into the set and tighten the pivot screw if necessary to keep the blades aligned.

Usage recommendations

Keep the blades clean and free of oil or debris to ensure accurate measurements. Store the set in a dry place to prevent corrosion and avoid excessive force when inserting blades into tight gaps to prevent bending.
