Precision Brand 19280 Flat Feeler Gage 0.5 in 10 Pack

Product Description

The PRECISION BRAND 19280 is a flat feeler gage leaf used to measure precise clearances and gaps in mechanical assemblies. Each leaf measures 0.5 inches thick and 5 inches in length, constructed from high-carbon steel for consistent hardness and wear resistance. The flat leaf profile allows straight-line insertion into tight tolerances where curved or tapered designs would not seat correctly. This package contains 10 leaves of identical thickness, making it a practical shop supply for machinists, HVAC technicians, engine rebuilders, and maintenance professionals who require repeatable gap measurement on the job.

Flat feeler gage leaves are used across a wide range of trade applications including valve clearance checks, bearing fits, mold and die alignment, and HVAC equipment service involving blower wheel or motor shaft tolerances. The 5-inch leaf length provides adequate reach into recessed assemblies without flexing under hand pressure. The 10-leaf pack quantity suits bench stock replenishment in machine shops, maintenance departments, and service vans that consume individual leaves through regular use or calibration cycles.

Key Features

• Flat leaf style for straight-line gap measurement in parallel surfaces
• 0.5 inch thickness per leaf for large-clearance measurement applications
• 5 inch leaf length provides reach into recessed or deep assemblies
• High-carbon steel construction resists wear and maintains dimensional stability
• 10-leaf pack for bench stock or multi-technician use

Compatibility

Designed as a standard flat feeler gage leaf for general-purpose gap and clearance measurement in mechanical, HVAC, and industrial maintenance applications.

Installation Notes

Feeler gage leaves should be inserted without forcing; if the leaf binds or buckles, select the appropriate thickness for the measured clearance. Wipe leaves clean of debris before use to avoid false readings. Store leaves flat and away from moisture to prevent corrosion of the high-carbon steel material. No power disconnection is required for most gap-measurement tasks, though always follow equipment-specific lockout procedures when working on energized or pressurized systems.
