Starrett 52799 Feeler Stock Roll 0.0025 in Tempered Steel

Product Description

The STARRETT 52799 is a tempered steel feeler stock roll used to measure and set precise gaps in mechanical assemblies, engine components, and industrial equipment. At 0.0025 inches thick and 0.5 inches wide, this roll provides a consistent, calibrated thickness throughout its 25-foot length. Technicians and machinists cut strips to length as needed, making it a flexible alternative to fixed-length feeler gauge blades. The tempered steel construction resists deflection and wear, maintaining dimensional accuracy under repeated use. This type of precision measuring stock is a standard item in HVAC, engine, and general mechanical service work.

Feeler stock rolls are used wherever precise gap measurement or setting is required — valve clearances, spark plug gaps, bearing fits, alignment checks, and equipment shimming applications. The 25-foot roll format is suited for high-volume shops, field service kits, and anywhere custom-length gauge strips are needed on demand. At 0.0025 inches thickness, this roll addresses some of the finest gap tolerances encountered in precision mechanical work.

Key Features

• Tempered steel construction for rigidity and dimensional stability
• 0.0025 inch thickness for fine-tolerance gap measurement
• 0.5 inch width provides a workable blade surface for most gap applications
• 25-foot roll length allows custom strip cutting to any required length
• Consistent thickness throughout the full roll length

Compatibility

Designed as a general-purpose precision measuring stock suitable for use in mechanical, HVAC, engine, and industrial service applications where 0.0025 inch gap tolerances are required.

Installation Notes

Cut strips to the required length using metal shears or a utility knife and straightedge before use. Deburr cut edges to avoid measurement error or surface damage on mating components. When using feeler stock as a gap-setting tool in live equipment, ensure the system is powered down or depressurized before inserting the gauge strip. Store the roll in a dry environment to prevent corrosion.
