Starrett 50654 Parallel Feeler Gage Set 8 Piece

Product Description

The STARRETT 50654 is an 8-piece parallel feeler gage set designed for precise gap measurement in mechanical and industrial applications. Each leaf is manufactured from tempered steel and measures 12 inches in length by 0.5 inches wide with a parallel profile — no taper from tip to handle. The set covers a measurement range of 0.002 to 0.015 inches across eight individual leaves, making it suitable for checking valve clearances, bearing fits, spark plug gaps, and similar close-tolerance tasks. HVAC technicians, machinists, and industrial maintenance trades use this type of set for routine service work where accurate gap verification is required.

This feeler gage set is appropriate for both residential and light commercial service environments. It is well suited for HVAC gas valve and burner component clearance checks, motor and compressor assembly inspections, and general mechanical maintenance where leaf-style gages are the specified measurement tool. The parallel leaf style keeps blade width consistent along the full 12-inch length, giving consistent contact across the measured gap.

Key Features

• Eight parallel leaves covering 0.002, 0.003, 0.004, 0.005, 0.006, 0.008, 0.010, and 0.015 inches
• Tempered steel construction for durability and resistance to deflection under use
• Parallel leaf style — uniform 0.5-inch width along the full 12-inch leaf length
• Closed length of 12 inches keeps the set compact and easy to store in a tool bag
• Fine minimum thickness of 0.002 inches supports close-tolerance gap checks

Compatibility

Designed as a general-purpose parallel feeler gage set suitable for mechanical, HVAC, plumbing, and industrial maintenance applications requiring gap measurement between 0.002 and 0.015 inches.

Installation Notes

Feeler gages require no installation, but proper use practice should be followed. Insert individual leaves into the gap with light, consistent drag — forcing a leaf can bend or score the blade. Clean leaves before and after use to prevent corrosion and maintain accuracy. Store the set closed to protect leaf edges from nicks that would affect measurement reliability.
