Precision Brand 19K3 Feeler Gage Set 0.0030 Inch 12 Leaves

Product Description

The PRECISION BRAND 19K3 is a flat-leaf feeler gage set used to measure precise clearances and gaps in mechanical assemblies. Each set includes 12 leaves of high-carbon steel, all cut to a uniform thickness of 0.003 inches. Leaves measure 12 inches in length and 0.5 inches in width, providing reach into tight clearance areas without flexing under light hand pressure. This gage set is a standard hand tool for HVAC technicians, machinists, and service professionals who need repeatable, accurate gap measurements during assembly, adjustment, or inspection work.

Flat feeler gages like the 19K3 are used across a wide range of service and installation scenarios. Common applications include checking valve clearances, setting contact gaps, verifying bearing end-play, and confirming fitment tolerances during equipment assembly or overhaul. The 12-inch leaf length suits applications where shorter blades cannot reach the measurement point. This set is appropriate for both shop bench work and field service environments where quick, reliable gap verification is needed.

Key Features

• Flat leaf profile for straightforward gap and clearance measurement
• 0.003 inch uniform leaf thickness across all 12 leaves in the set
• 12-inch leaf length provides extended reach into deep or recessed assemblies
• 0.5 inch leaf width gives a stable measurement surface
• High-carbon steel construction resists wear and maintains dimensional accuracy under repeated use
• 12-leaf count supports versatile use across multiple clearance specifications

Compatibility

Designed as a standard flat feeler gage set suitable for general mechanical service, HVAC equipment maintenance, and industrial assembly applications requiring 0.003 inch clearance measurement.

Installation Notes

Feeler gages are a hand measurement tool and do not require installation. Power down or de-energize any equipment before inserting a feeler gage into an operating assembly. Apply only light hand pressure when inserting the leaf to avoid bending or permanently deforming the blade. After use, wipe leaves clean and return them to the holder to prevent corrosion and maintain accuracy.
