Starrett 52809 Feeler Stock Roll 0.012 in Tempered Steel

Product Description

The STARRETT 52809 is a tempered steel feeler stock roll used for measuring and setting precise gaps in mechanical assemblies. At 0.012 inches thick and 0.5 inches wide with 25 feet of usable length, this roll gives technicians the flexibility to cut custom-length feeler gauge strips to fit a wide range of clearance-check applications. Tempered steel construction provides consistent thickness, hardness, and resistance to deformation under repeated use. HVAC techs, machinists, and field service professionals reach for stock rolls when standard feeler gauge sets do not offer the exact blade length or shape required for the job.

Feeler stock rolls are used across residential and commercial service environments wherever precise gap measurement or clearance setting is required. Common applications include setting valve clearances, checking bearing clearances, verifying burner orifice alignment, inspecting motor air gaps, and fitting shims during equipment assembly or rebuild. The 25-foot length provides enough material for a full shop supply or repeated field cuts without frequent restocking. The 0.5-inch width suits most standard gap-check tasks while still fitting into tight clearance areas on HVAC equipment and mechanical systems.

Key Features

• Tempered steel construction delivers consistent thickness and resistance to bending or deformation
• 0.012-inch thickness for precise gap measurement in tight-tolerance applications
• 0.5-inch width fits most standard clearance-check scenarios including motor air gaps and valve seats
• 25-foot roll length allows custom blade cuts for non-standard lengths and shapes
• Single-roll packaging suits individual technicians and small shop inventories

Compatibility

Designed as a general-purpose feeler stock roll suitable for use in HVAC, mechanical, and industrial service applications where 0.012-inch gap measurement stock is required.

Installation Notes

Cut feeler stock to the required length using aviation snips or metal shears rated for thin-gauge steel. Deburr cut edges before use to avoid false gap readings or surface scratches on precision components. Always power down or lock out equipment before inserting feeler stock into rotating or energized assemblies. Handle edges with care, as cut tempered steel strip edges can be sharp.
