Starrett 73394 Feeler Stock Roll 0.0005 in Stainless Steel

Product Description

The STARRETT 73394 is a precision feeler stock roll made from stainless steel, designed for measuring and setting tight clearances in mechanical assemblies. At 0.0005 inches thick, this roll provides an ultra-thin gauging reference suitable for verifying critical gaps in valves, bearings, fuel system components, and other close-tolerance applications. The 0.5-inch width and 12-inch length offer enough material for a variety of layout and inspection tasks. HVAC technicians, machinists, and mechanical contractors rely on feeler stock like this when standard feeler gauge blades are too short or when a custom-cut strip is needed for a specific clearance check.

This feeler stock roll is well suited for residential and commercial mechanical service work where gap verification is part of a routine inspection or installation procedure. The stainless steel construction resists corrosion and holds its calibrated thickness even in humid or wet environments, making it a practical choice for plumbing and HVAC service settings. The 12-inch roll length allows strips to be cut to custom lengths as required by the application.

Key Features

Compatibility

Designed as a general-purpose precision feeler stock for use in mechanical, HVAC, plumbing, and electrical service applications requiring ultra-thin gap measurement references.

Installation Notes

Feeler stock is a measurement and layout tool installed by machinists, HVAC technicians, and mechanical contractors. Always de-energize and isolate any equipment before using feeler stock to check internal clearances. Use shears or a sharp utility blade to cut strips to the required length; avoid bending or creasing the stock, as this will affect its calibrated thickness. Handle with clean, dry hands to prevent surface contamination that could influence measurement accuracy.
