Starrett 64949 Parallel Feeler Gage Set 14 Piece

Product Description

The STARRETT 64949 is a 14-piece parallel feeler gage set designed for precise gap and clearance measurement across a range of 0.03 to 0.50 mm. Each leaf is manufactured from tempered steel and measures 300 mm (approximately 11.81 inches) in length and 12.70 mm (approximately 0.50 inches) in width. The parallel leaf profile maintains a consistent width along the full length, delivering repeatable contact when measuring valve clearances, bearing tolerances, mating surface gaps, and similar tight-tolerance applications. The set weighs approximately 1.5 pounds and is suited for bench work or field service.

This feeler gage set is used in mechanical and industrial maintenance settings where precise thickness measurement is required. Common applications include engine valve lash adjustment, transmission clearance checks, machined surface inspection, and alignment verification on industrial equipment. The parallel leaf style is preferred when full-length contact across the measurement surface is needed, as opposed to tapered blades that offer a single-point read. Licensed mechanics, millwrights, HVAC technicians setting compressor valve clearances, and general maintenance professionals will find this set appropriate for daily shop use.

Key Features

• 14 leaves covering 0.03, 0.04, 0.05, 0.06, 0.08, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, and 0.50 mm
• Parallel leaf style provides consistent full-length contact for reliable gap measurement
• Tempered steel construction for durability and resistance to flex fatigue
• 300 mm leaf length accommodates deep or extended clearance measurements
• Compact closed profile at 300 mm length and 12.70 mm width for easy storage and portability

Compatibility

Designed as a general-purpose parallel feeler gage set suitable for mechanical, industrial, and HVAC service applications requiring metric gap measurement in the 0.03 to 0.50 mm range.

Installation Notes

Feeler gages require no installation but should be handled with care to avoid kinking or bending individual leaves. Before measuring, clean both the gage leaf and the surfaces being measured to remove debris or oil that would affect accuracy. Store leaves in the closed position to prevent damage. Calibration against a known reference standard is recommended when measurement traceability is required.
