Spi 91-449-9 Feeler Stock Roll 0.032 in High Carbon Steel

Product Description

The SPI 91-449-9 is a high carbon steel feeler stock roll used for precise gap measurement and clearance checking in mechanical and maintenance applications. Supplied in a continuous roll format, this feeler stock measures 0.032 inches thick and 0.5 inches wide, giving technicians a consistent reference surface for checking tolerances on gaskets, valves, bearings, and mating components. At 25 feet per roll, it provides ample material for custom-cut feeler strips or direct use as a bench stock item. High carbon steel construction delivers the hardness and spring-back characteristic needed for repeatable, accurate measurement work.

This feeler stock roll is suited for HVAC service, industrial maintenance, and mechanical repair environments where standard pre-cut feeler gauge sets do not cover the required thickness or where custom-length strips are needed. Technicians use rolls like this when building custom feeler sets, cutting shims, or verifying clearances on compressors, motor bearings, valve seats, and similar components. The 0.5-inch width accommodates most standard gap-checking tasks without excessive material waste when strips are cut to length.

Key Features

• 0.032-inch thickness for precise gap and clearance measurement
• 0.5-inch wide strip allows easy handling and custom cutting
• 25-foot continuous roll provides generous material per unit
• High carbon steel construction delivers consistent hardness and spring-back
• Roll format suits both bench stock and field use

Compatibility

Designed as a general-purpose feeler stock roll suitable for use in any application requiring 0.032-inch thickness gap measurement strips cut from a continuous high carbon steel roll.

Installation Notes

Feeler stock rolls are handled and cut by machinists, HVAC technicians, and maintenance mechanics using metal snips or a bench shear. Cut edges may be sharp — use appropriate hand protection when trimming strips to length. Ensure the work surface and the component being checked are free of debris before taking clearance measurements to avoid false readings.
