Stanley J000R Feeler Gage Set 16 Leaves Steel

Product Description

The STANLEY J000R is a 16-leaf steel feeler gage set used to measure small gaps and clearances with precision. Each leaf is stamped from steel and sized to a specific decimal thickness, giving technicians a direct-reading tool for spark plug gaps, valve clearances, brake shoe-to-drum clearances, and similar close-tolerance checks. The set spans 0.0090 to 0.0270 inch across 16 discrete thicknesses. Individual leaves measure 0.0435 inches in length and 1/4 inch in width, making them suitable for tight access points. The complete set weighs 0.25 pounds and ships as a single-unit package.

This feeler gage set is suited for automotive, HVAC, and general mechanical service work where precise gap measurement is required. Typical applications include setting ignition points, checking valve lash on small engines, verifying carburetor float drop, and measuring bearing clearances. The compact leaf size is well matched to confined spaces encountered during engine and equipment service in both shop and field environments.

Key Features

• 16 steel leaves covering 0.0090 to 0.0270 inch in graduated steps
• Leaf length of 0.0435 inches and 1/4 inch width for access in tight spaces
• Steel construction for durability and resistance to bending under normal use
• Each leaf stamped to a distinct decimal inch thickness for direct measurement
• Lightweight at 0.25 pounds for easy carry in a tool pouch or kit bag

Compatibility

Designed as a general-purpose feeler gage set suitable for automotive, mechanical, and HVAC service applications requiring gap measurements in the 0.0090 to 0.0270 inch range.

Installation Notes

Insert the appropriate leaf into the gap being measured without forcing it; the correct thickness is the thinnest leaf that produces a slight drag when pulled through. Clean leaves before and after use to prevent corrosion and maintain accuracy. Do not bend or kink leaves during use, as permanent deformation will affect measurement accuracy. This tool requires no special trade license but is commonly used by licensed HVAC technicians, automotive mechanics, and industrial maintenance professionals.
