Feeler Gauge Set Gimex 100 mm 0.03–0.10 mm 8-piece 318.021

Feeler Gauge Set Gimex 100 mm 0.03–0.10 mm 8-piece 318.021 is a compact tool set designed for measuring very small clearances and gaps in mechanical assemblies. The set includes eight 100 mm blades covering thicknesses from 0.03 mm to 0.10 mm, enabling accurate assessment of valve clearances, bearing play and joints where thin tolerances are critical. Blades are sized to provide incrementally different feeler thicknesses for fine adjustment and inspection tasks.

Advantages

The set offers a precise range of thin blades that fit tight tolerances, allowing consistent and repeatable measurements. Its compact eight-blade configuration makes it easy to carry and use in workshop or field environments. The 100 mm blade length provides reliable handling and reach for accessing narrow or recessed components. Materials and finish are selected to reduce wear and maintain blade flatness over repeated use.

Suitable for

• Checking valve clearances on internal combustion engines
• Measuring bearing play and shaft end-float
• Inspecting gasket and joint gaps during assembly
• Fine setting and calibration of mechanical linkages

Key specifications

• Blade length: 100 mm
• Number of blades: 8
• Thickness range: 0.03 mm to 0.10 mm
• Material: hardened and ground feeler blades (steel)
• Typical use: precision clearance measurement in mechanical and engine maintenance

How to use

Select the blade or combination of blades that approximates the gap to be measured. Insert the blade between mating surfaces and feel for a slight drag to determine fit; a light friction indicates the clearance equals the blade thickness. For tighter or intermediate measurements, combine blades by stacking them until the desired feel is achieved. After use, clean blades of debris and store the set in its holder to protect blade edges and maintain measurement accuracy.

Usage recommendations

Use in clean, dry conditions and avoid bending or prying with the blades to preserve flatness. For engine valve adjustments, verify measurements with the engine cold unless the procedure specifies otherwise. Keep blades free of oil and corrosion; apply light oil only for storage if needed.
