Precision Brand 09105 Feeler Gage 0.001 in Flat Leaf

Product Description

The PRECISION BRAND 09105 is a flat-leaf feeler gage blade used for measuring small gaps and clearances in mechanical assemblies. At 0.001 inch (0.05 mm) thick and 25 inches long, this single blade suits applications where a precise, thin reference is required to check tolerances on engine components, valve clearances, bearing fits, and machinery alignments. Constructed from high-carbon steel, the blade resists flex under normal measuring loads while maintaining dimensional accuracy. HVAC techs, millwrights, machinists, and general maintenance professionals keep feeler gage blades in their service kits for periodic inspection tasks and component setup work.

This blade is suited for both field service and shop environments where gap measurement is part of routine maintenance or equipment setup. The 25-inch leaf length provides reach into deeper assemblies or allows multiple measurements along an extended surface. The flat leaf style lays flush against mating surfaces, giving a reliable go/no-go feel when checking clearances. At 0.50 inch wide, the blade fits into standard-width slots and most commercial feeler gage holders.

Key Features

• 0.001 inch (0.05 mm) blade thickness for fine-tolerance gap measurement
• 25 inch (635 mm) leaf length for reach into deep or extended assemblies
• Flat leaf style for flush contact against mating surfaces
• 0.50 inch (12.7 mm) blade width fits standard feeler gage holders
• High-carbon steel construction for durability and dimensional stability

Compatibility

Designed as a standard replacement or supplemental blade compatible with most commercial flat-leaf feeler gage sets and holders that accept 0.50 inch wide blades.

Installation Notes

Feeler gage blades are precision measuring tools and should be handled by qualified technicians or tradespeople familiar with tolerance measurement procedures. Always clean the blade and mating surfaces before measuring to prevent debris from skewing readings. Do not force a blade into a gap that requires excessive pressure, as this can bend the leaf and permanently affect calibration. Store blades flat and protected from moisture to prevent corrosion of the high-carbon steel.
