Gearwrench 161D Feeler Gauge Set 32 Leaf Steel

Product Description

The GEARWRENCH 161D is a 32-leaf feeler gauge set used to measure precise clearances between mating components in mechanical assemblies. Each leaf measures 3.31 inches long and 0.5 inches wide, with a maximum thickness of 0.5 inches across the set. The leaves are constructed from steel for durability and resistance to wear during repeated use. This type of gauge is standard equipment for setting valve clearances, spark plug gaps, bearing clearances, and other tight-tolerance fits. It is commonly used by automotive technicians, diesel mechanics, machinists, and HVAC technicians during equipment assembly or preventive maintenance procedures.

The 161D feeler gauge set is suited for both shop and field service applications where precise gap measurement is required. With 32 individual leaves in a single set, technicians can quickly fan through multiple thickness increments to find the correct fit. The compact leaf dimensions make it practical for access in confined spaces typical of engine compartments, compressor assemblies, and mechanical equipment enclosures. This set is appropriate for professional trade use in automotive, mechanical, and light industrial service environments.

Key Features

• 32 individual steel leaves for a wide range of thickness increments in one set
• Each leaf is 3.31 inches long and 0.5 inches wide for consistent measurement geometry
• Steel construction provides durability and dimensional stability under repeated use
• Compact leaf size allows access in confined clearance spaces
• Single-set design keeps all leaves organized and together for field use

Compatibility

Designed as a general-purpose feeler gauge set suitable for gap and clearance measurement tasks across automotive, mechanical, and light industrial service applications.

Installation Notes

Feeler gauges require no installation but should be handled carefully to avoid bending individual leaves, which can introduce measurement error. Keep leaves clean and lightly oiled to prevent corrosion and ensure smooth operation. When measuring a gap, insert the appropriate leaf with light drag resistance as the acceptance criterion — forcing a leaf can damage both the gauge and the component. Store the set fully closed when not in use to protect leaf integrity.
