Spi 91-426-7 Feeler Stock Roll 0.009 in High Carbon Steel

Product Description

The SPI 91-426-7 is a high carbon steel feeler stock roll used for precise gap measurement and clearance checking in mechanical and industrial service work. Cut to length as needed, this roll stock provides consistent thickness across its full 25-foot length, making it a reliable choice for fabricating custom feeler gauges or shims on the job. At 0.009 inches thick and 0.5 inches wide, it delivers repeatable dimensional accuracy for tight-tolerance applications. Machinists, maintenance technicians, and HVAC service professionals use feeler stock when factory-gauged strips are not the right length or width for the task at hand.

This feeler stock roll suits applications in residential and commercial maintenance environments where technicians need to verify bearing clearances, valve lash, burner orifice spacing, or other small gaps. The roll format allows the user to cut a strip to any required length, which is practical when working on equipment with non-standard access geometry. High carbon steel construction provides the stiffness and surface hardness needed to slide cleanly into tight gaps without deflecting or folding under light pressure.

Key Features

• 0.009-inch thickness for fine clearance measurement
• 0.5-inch width accommodates a range of gap geometries
• 25-foot roll length provides material for multiple custom-cut strips
• High carbon steel construction delivers consistent stiffness and hardness
• Roll format allows field-cut strips of any required length

Compatibility

Designed as a general-purpose feeler stock roll suitable for gap measurement and shimming tasks across mechanical, HVAC, and industrial maintenance applications where a 0.009-inch thickness is required.

Installation Notes

Cut strips to the required length using metal shears or a utility knife scored against a straightedge. Wear gloves when handling cut edges, as high carbon steel edges can be sharp. Ensure all equipment being measured is powered down and de-energized before inserting the feeler stock into any gap. Discard bent or kinked strips, as deformation affects measurement accuracy.
