Feeler Gauge Set Forsage F-61804 — 32 Blades 0.04–0.88 mm

The Feeler Gauge Set Forsage F-61804 — 32 Blades 0.04–0.88 mm is a compact folding leaf gauge set designed for precise measurement of clearances and gaps. The set includes 32 individual blades with incremental thicknesses from 0.04 mm up to 0.88 mm, arranged for easy selection and stable positioning. Constructed for workshop and field use, the blade set is suitable for checking valve clearances, spark plug gaps, bearing endplay and shim thickness where accurate, repeatable measurements are required.

Advantages

The folding design keeps blades organized and protected when not in use and allows quick access during measurement tasks. Individual blades are stamped with thickness markings for straightforward identification, and the range of sizes covers common fine adjustments encountered in engine and machinery maintenance. The compact profile and durable pivot hold blades securely while allowing a smooth fan-out motion for selecting the required thickness.

Suitable for

• Measuring valve clearances on petrol and diesel engines
• Setting spark plug gaps and checking ignition components
• Measuring bearing clearances and shaft endplay
• Checking shim thickness and performing precision assembly adjustments
• General gap measurement in maintenance, repair and inspection tasks

Key specifications

• Number of blades: 32
• Blade thickness range: 0.04–0.88 mm
• Blade style: leaf/folding design for compact storage
• Material: hardened steel blades (corrosion-resistant finish)
• Markings: stamped thickness values on individual blades

How to use

Select the blade thickness closest to the required clearance and fan it out from the holder. Insert the blade between the two parts whose gap you want to measure, sliding gently until you feel a light drag indicating the correct fit. For tighter tolerances, try adjacent blade combinations or feeler stacking to achieve the precise thickness. After use, fold blades back into the holder to protect edges and maintain organized storage.

Usage recommendations

Clean contact surfaces before measurement and ensure blades are free of oil or debris for accurate readings. Use light, consistent pressure when gauging gaps and avoid forcing oversized blades into a clearance to prevent blade damage. Store the set in a dry location and wipe blades with a lightly oiled cloth if prolonged storage or corrosion protection is required.
