Starrett 52883 Parallel Feeler Gage Set 108 Piece

Product Description

The STARRETT 52883 is a 108-piece parallel feeler gage set designed for precise gap measurement in industrial, mechanical, and trade service applications. Each leaf is manufactured from tempered steel and measures 12 inches in length by 0.5 inches in width, with a parallel profile that maintains consistent thickness along the full leaf length. The set covers a thickness range of 0.0015 to 0.015 inches, giving technicians a broad selection of leaf sizes for checking clearances on valves, bearings, contacts, and fastener gaps. HVAC technicians, machinists, and maintenance professionals use this set for commissioning and service work requiring tight dimensional tolerance verification.

This feeler gage set is suited for residential and commercial maintenance environments where accurate gap measurement is required. Typical applications include checking valve clearances, spark plug gaps, bearing fits, and contact point spacing on mechanical and electromechanical equipment. The parallel leaf style is appropriate for measuring gaps with flat, parallel surfaces. All 108 leaves are organized in a single set for fast leaf selection during service calls.

Key Features

• 108 leaves total, grouped in 9 thickness values with 12 leaves each
• Thickness range spans 0.0015 to 0.015 inches for broad coverage
• Parallel leaf profile ensures uniform thickness along full 12-inch length
• Tempered steel construction for durability and dimensional stability
• Leaf width of 0.5 inches accommodates standard gap measurement tasks
• Closed length of 12 inches for organized storage and portability

Compatibility

Designed as a general-purpose parallel feeler gage set for use in mechanical, HVAC, and industrial maintenance applications where gap measurements within the 0.0015 to 0.015 inch range are required.

Installation Notes

Feeler gages are a hand tool requiring no power source; however, always de-energize and lock out electrical or mechanical equipment before inserting leaves into live assemblies. Select the appropriate leaf thickness and insert it with light, consistent hand pressure — forcing a leaf can cause permanent deformation and affect calibration accuracy. Clean leaves after each use and store them fully closed to protect against corrosion and physical damage. Periodic inspection for burrs or bends is recommended to maintain measurement integrity.
