Starrett 52812 Feeler Stock Roll 0.015 in Tempered Steel

Product Description

The STARRETT 52812 is a tempered steel feeler stock roll used for precision gap measurement and clearance checking in mechanical, HVAC, and industrial service applications. The roll measures 0.015 inches thick and 0.5 inches wide, providing a consistent, reliable gauge surface across its full 25-foot length. Tempered steel construction ensures the material holds its shape under repeated use without permanent deformation. Technicians cut strips to the length needed for the job, making this roll a practical alternative to fixed-blade feeler gauge sets when non-standard lengths or custom configurations are required.

This feeler stock is suited for field and shop use by HVAC technicians, millwrights, machinists, and general service professionals who need accurate gap measurement in tight clearances. Common applications include checking valve clearances, bearing fits, burner assembly alignment, heat exchanger gap verification, and equipment alignment tasks where a rigid feeler blade cannot reach. The 25-foot roll format makes it economical for shops that perform high-volume measurement work or need to cut multiple strips for a single job.

Key Features

• Tempered steel construction resists permanent bending and maintains dimensional accuracy across the roll
• 0.015 inch thickness provides a precise reference for tight clearance measurements
• 0.5 inch width accommodates a range of gap measurement scenarios
• 25-foot continuous roll allows custom strip lengths to be cut as needed
• Consistent thickness throughout the roll length supports repeatable measurements

Compatibility

Designed as a general-purpose feeler gauge stock for use in any application requiring 0.015 inch gap measurement, including mechanical assembly, HVAC equipment servicing, and industrial maintenance tasks where standard feeler blade sets are impractical.

Installation Notes

Use sharp metal shears or a bench-mounted cutter to cut strips cleanly without distorting the edges, which can affect measurement accuracy. When checking clearances, slide the stock into the gap with light, consistent hand pressure and never force it through a fit. Handle cut edges carefully, as freshly cut tempered steel can be sharp. No special tools or codes govern the use of feeler stock, but technicians should follow applicable equipment manufacturer guidelines for allowable clearance tolerances.
