Starrett 57088 Tapered Feeler Gage Set 13 Piece

Product Description

The STARRETT 57088 is a 13-piece tapered feeler gage set designed for precise gap measurement in maintenance, machining, and assembly applications. Each leaf is manufactured from tempered steel and features a tapered profile that widens from 7mm to 12.7mm along a 152mm working length. The set covers a measurement range of 0.03mm to 0.50mm across 13 graduated leaves, giving technicians the resolution needed for close-tolerance work on engine components, valve clearances, bearing fits, and similar critical gaps. Machinists, mechanics, and field service technicians working in metric environments will find this set a reliable everyday tool.

This set is suited for residential and commercial maintenance environments, precision machine shops, and field service applications where metric gap measurement is required. The tapered leaf design allows the blade to self-guide into tight clearances, making it useful for valve lash checks, spark plug gap verification, conveyor alignment, and general assembly quality control. The compact closed length of 152mm keeps the set manageable in a toolbox or service pouch.

Key Features

• 13 tapered leaves covering 0.03mm to 0.50mm in fine increments
• Tempered steel construction for durability and consistent spring-back
• Tapered blade profile widens from 7mm to 12.7mm for self-guiding entry into tight gaps
• 152mm leaf length provides reach into recessed clearances
• Full metric increment set: 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50mm
• Compact folded form factor at 152mm closed length for portability

Compatibility

Designed as a general-purpose metric feeler gage set suitable for engine, mechanical, and precision assembly applications requiring gap measurement in the 0.03mm to 0.50mm range.

Installation Notes

Feeler gages require no installation but should be handled by qualified mechanics or technicians familiar with gap measurement procedures. Always clean the blades and the measured surfaces before use to avoid false readings caused by debris or oil film buildup. Fan the leaves open carefully to avoid bending individual blades, and never force a blade into a gap that is tighter than its rated thickness. Store the set folded and dry to prevent corrosion of the tempered steel leaves.
