Precision Brand 19145 Steel Feeler Gage Blade

Product Description

The PRECISION BRAND 19145 is a single-blade steel feeler gage manufactured from close-grain, high-carbon spring steel stock. The blade measures 0.5 inches wide by 12 inches long with a thickness of 0.0015 inches. The material is ground and polished to precision tolerances, making it suitable for measuring tight clearances, setting gaps, and checking fits in a wide range of mechanical and industrial applications. Machinists, millwrights, HVAC technicians, and engine rebuild professionals rely on feeler gage blades like this one for accurate clearance verification during assembly and maintenance.

This blade is well suited for residential and commercial service work where precise gap measurement is required. Common applications include checking valve clearances, setting igniter or spark gaps, verifying bearing clearances, and inspecting machined mating surfaces. The 12-inch blade length provides enough reach for recessed components, and the 0.5-inch width fits standard feeler gage handles and most blade-retainer sets.

Key Features

• Ground and polished high-carbon spring steel for repeatable, accurate thickness across the full blade length
• Blade thickness of 0.0015 inches for measuring very close-tolerance gaps
• 12-inch blade length offers extended reach for hard-to-access clearance points
• 0.5-inch blade width fits standard gage holders and retainer sets
• Sold individually, allowing replacement of a single blade without purchasing a full set

Compatibility

Designed as an OEM-style replacement or supplemental blade for standard feeler gage sets that accept 0.5-inch-wide, 12-inch-long blades.

Installation Notes

Feeler gage blades are a hand-measurement tool and require no installation in the electrical or mechanical sense. Ensure the surface to be measured is clean and free of debris before inserting the blade to avoid false readings or blade damage. Do not force a blade into a gap narrower than its rated thickness, as this can permanently deform the blade and compromise accuracy. Store blades flat and dry to prevent warping and corrosion.
