Starrett 52796 Thickness Gauge Roll 25 Ft 0.001 in

Product Description

The STARRETT 52796 is a precision feeler gauge in roll form, designed for measuring and adjusting tight clearances in mechanical systems. The 666-1 roll spans 25 feet and is cut to length as needed, giving technicians a flexible alternative to fixed-blade gauge sets. At 0.001 inch thickness, it suits fine-tolerance work. The gauge stock is constructed from tempered steel for consistent accuracy and resistance to deformation under repeated use. It ships in a compact plastic dispenser case that rewinds the stock for clean storage between jobs. Markings appear every 6 inches (150 mm) along the roll length, supporting both imperial and metric measurement workflows.

This gauge roll is used in automotive, small engine, and light industrial maintenance work. Typical applications include setting tappet clearances, gapping spark plugs, and checking distributor point gaps. The roll format allows the technician to trim a working piece to fit confined spaces or wrap around curved surfaces where rigid blades do not seat cleanly. It is suited to both shop bench work and field service calls where a compact, reusable gauge supply is an advantage.

Key Features

• Tempered steel construction for dimensional stability and long service life
• 25-foot roll length provides cut-to-size flexibility for varied clearance jobs
• 0.001 inch nominal thickness for fine-tolerance measurement
• Marked every 6 inches and 150 mm for dual imperial and metric reference
• Compact plastic dispenser case with rewind function for tidy storage

Compatibility

Designed as a general-purpose feeler gauge stock for automotive, small engine, and light industrial applications requiring 0.001 inch clearance measurement.

Installation Notes

Feeler gauge work is typically performed by automotive technicians, small engine mechanics, and maintenance trades. Before measuring valve or ignition clearances, shut down the engine and allow it to cool to prevent contact with hot components. Cut the gauge stock with sharp metal shears for a clean edge, and avoid kinking the strip, which can introduce measurement error. Refer to the equipment manufacturer's service manual for specified clearance values before use.
