Gap feeler gauge set HOGERT HT8G330, 0.04–0.30 mm, 9 pieces

The HOGERT Gap feeler gauge set HT8G330 is a compact 9-piece tool kit for measuring small clearances and valve gaps with blade thicknesses from 0.04 to 0.30 mm. Designed for automotive maintenance, engine tuning and mechanical inspection, the set provides precise, repeatable measurements in a portable, workshop-ready format. Each blade is marked with its thickness for quick identification and the holder keeps blades organized and protected during transport and storage.

Advantages

This feeler gauge set offers accurate blade tolerances across a useful range for common engine and mechanical tasks, enabling reliable clearance checks. The compact holder and clear markings simplify selection and reduce measurement errors, while durable blade material resists wear for consistent performance. The set's small size makes it convenient for both bench work and field service.

Suitable for

• Measuring valve clearances on petrol and diesel engines
• Checking small gaps and tolerances in mechanical assemblies
• Adjusting ignition points or valve tappets during engine tuning
• Quality control inspections in workshops and manufacturing
• Portable field service and on-site maintenance tasks

Key specifications

• Number of blades: 9
• Blade thickness range: 0.04–0.30 mm
• Individual blade identification: thickness markings on each blade
• Holder: compact metal/steel holder for blade organization
• Intended use: precision gap measurement for automotive and mechanical applications

How to use

Select the blade corresponding to the nominal clearance to be checked and insert it between the two surfaces to measure. A correct fit will allow the blade to slide with slight resistance; if it is too loose or too tight, try the next thicker or thinner blade until the correct feel is obtained. Work on clean contact surfaces and ensure the engine or mechanism is in the specified position for accurate measurement. After use, fold the blades back into the holder to protect edges and maintain organization.

Usage recommendations

Use the feeler blades on clean, dry surfaces and avoid excessive lateral force that can damage blade edges. Store the set in a dry environment to prevent corrosion and check blade condition periodically; replace any deformed blades to maintain measurement accuracy.
