InSize 4206-1 Telescoping Gauge Set 5/16 to 6 Inch

The InSize 4206-1 Telescoping Gauge Set provides precise internal measurement capabilities for holes, slots, grooves, and recesses ranging from 5/16 inch to 6 inches in diameter. This professional-grade measuring tool set is essential for machinists, mechanics, and quality control inspectors who need accurate inside diameter measurements.

Key Features:

• Measurement range: 5/16 inch to 6 inches for versatile application coverage
• Spring-loaded plungers ensure consistent contact pressure for repeatable measurements
• Hardened and ground contact points provide durability and measurement accuracy
• Knurled handle design offers secure grip and precise control during use
• Individual locking mechanisms maintain measurement for transfer to micrometers or calipers
• Complete set includes multiple gauges to cover the full measurement range

Telescoping gauges work by inserting the compressed gauge into the bore, releasing the plungers to contact the walls, then locking and removing for measurement with external measuring tools. This set is ideal for inspecting cylinders, bushings, and other internal dimensions where direct measurement is difficult.
