Precision Brand 19210 Steel Feeler Gage Blade 0.003 in

Product Description

The PRECISION BRAND 19210 is a single steel feeler gage blade designed for precise gap measurement in mechanical and industrial applications. Manufactured from high-carbon spring steel, the blade is ground and polished to tight tolerances, making it suitable for checking clearances on valves, bearings, gaskets, and similar components. At 0.003 inches thick and 0.5 inches wide with a 12-inch length, this blade provides reliable dimensional reference where accurate gap measurement is critical. Technicians across HVAC, mechanical, and general maintenance trades rely on feeler gage blades like this one for routine calibration and inspection tasks.

This feeler gage blade is suited for residential and commercial service environments where precise gap measurement is required. Common applications include checking spark plug gaps, valve clearances, bearing fits, and machined surface tolerances. Its 12-inch length provides reach into confined or extended workspaces, and the 0.5-inch blade width offers a stable contact surface for consistent readings. The blade is sold individually and is compatible with standard feeler gage holders or used as a standalone blade.

Key Features

• 0.003-inch blade thickness for fine-tolerance gap measurement
• High-carbon spring steel construction, ground and polished to precision tolerances
• 0.5-inch blade width provides stable contact surface
• 12-inch blade length allows reach into extended or confined areas
• Close-grain steel stock for consistent material properties throughout the blade

Compatibility

Designed as an OEM-style replacement or supplemental blade for standard feeler gage sets requiring a 0.003-inch thickness in a 0.5-inch by 12-inch format.

Installation Notes

Feeler gage blades are a hand-measurement tool and require no installation in the traditional sense. Store blades flat and clean to prevent bowing or surface contamination that could affect measurement accuracy. When measuring clearances on powered equipment, ensure the equipment is fully de-energized and depressurized before inserting the blade. Avoid forcing the blade into a gap, as this can deform the blade and compromise its calibrated thickness.
