Precision Brand 19240 Steel Feeler Gage Coil 0.004 in X 25 Ft

Product Description

The PRECISION BRAND 19240 is a steel feeler gage coil used to measure and set precise gaps in mechanical assemblies. Manufactured from close-grain, high-carbon spring steel that has been ground and polished to precision tolerances, this coil measures 0.004 inches thick and 0.5 inches wide, supplied in a 25-foot continuous length. The coil format allows technicians to cut custom-length strips as needed rather than working with fixed-length blades, making it well-suited for applications requiring non-standard strip lengths or high-volume use.

This feeler gage coil is used in a wide range of trade and industrial applications where precise gap measurement is required. Common applications include setting valve clearances, spark plug gaps, breaker point gaps, bearing clearances, and machined assembly tolerances. It is used by HVAC technicians, diesel mechanics, machinists, and maintenance professionals working on equipment where tight dimensional control is critical. The coil format is particularly practical in maintenance environments where blade sets may not offer the exact length or quantity needed for a task.

Key Features

• 0.004 inch thickness ground and polished to precision tolerances
• 0.5 inch wide strip provides consistent coverage across gap measurement surfaces
• 25-foot continuous coil allows custom-length strips to be cut on site
• Close-grain, high-carbon spring steel construction for durability and consistent flex behavior
• Ground and polished finish ensures accurate, repeatable measurements

Compatibility

Designed as a general-purpose precision feeler gage coil suitable for gap measurement tasks across mechanical, HVAC, and industrial maintenance applications where a 0.004 inch gauge thickness is specified.

Installation Notes

This product is used by mechanics, machinists, and service technicians for gap measurement and is not a permanently installed component. Cut desired strip lengths using metal shears or a suitable cutting tool. Edges of cut strips may be sharp — use appropriate hand protection when handling freshly cut sections. Store the coil away from moisture to prevent corrosion of the carbon steel material.
