Starrett 63274 Parallel Feeler Gage Set 32 Piece

Product Description

The STARRETT 63274 is a 32-piece parallel feeler gage set designed for precise gap and clearance measurement in mechanical and maintenance applications. Each leaf is manufactured from tempered steel, providing the rigidity and durability required for accurate repeated use. The set covers a thickness range of 0.001 to 0.030 inches, making it suitable for a wide range of tolerance checks. Leaves measure 12 inches in length and 0.5 inches in width, with all leaves sharing the same parallel profile for consistent edge-to-edge contact across the full leaf length. The set weighs 2 pounds.

This feeler gage set is used by HVAC technicians, machinists, millwrights, and maintenance professionals for tasks such as checking valve clearances, setting igniter gaps, verifying burner electrode spacing, and confirming bearing fits. The 12-inch leaf length provides reach into confined equipment spaces, and the parallel leaf style ensures uniform thickness readings without taper-induced measurement error. Suitable for both shop and field service environments.

Key Features

• 32 leaves covering 0.001 to 0.030 inches thickness range
• Parallel leaf profile — uniform thickness along full 12-inch length
• Tempered steel construction for wear resistance and dimensional stability
• Leaf dimensions: 12 inches long by 0.5 inches wide
• Compact closed form at 12 inches closed length for tool storage and transport

Compatibility

Designed as a general-purpose parallel feeler gage set for mechanical clearance and gap measurement tasks across HVAC, industrial, and maintenance applications.

Installation Notes

Insert leaves into the gap being measured using light hand pressure only — forcing a leaf can bend or distort it and introduce measurement error. Clean leaves before and after use to prevent debris from affecting readings. Store the set closed to protect leaf edges from damage. No tools are required for use; calibration verification should follow the applicable shop or field metrology procedure.
