RS Pro Stainless Steel M20 Index Plunger, 69mm Long

The 237‑817 is a precision‑engineered indexing plunger featuring an M20 thread size and a 69 mm body length, designed for accurate locking and positioning. The unit offers strong corrosion resistance and smooth operation in industrial conditions. Its thread form and extended length make it especially suitable for applications that require deeper engagement or where standard plungers fall short in travel or reach.

Notable Advantages of this Stainless Steel M20 Index Plunger

• M20 threaded body allows secure installation in standard metric tapped holes.
• 69 mm overall length supports deeper locking positions and extended engagement.
• Stainless steel / nickel‑plated plunger construction improves durability and corrosion resistance.
• Indexing mechanism delivers repeatable locking in defined positions.
• Body design supports installation with a lock‑nut or a fixed body configuration.

Engineered for Precision Positioning

This indexing plunger is built to provide reliable, repeatable locking in high‑use and precision applications. The robust stainless steel body handles mechanical load, while the indexing pin and mechanism maintain positional integrity under vibration or load changes. The extended 69 mm length provides flexibility in applications where standard short plungers cannot achieve the desired engagement depth.

Typical Uses of the Plunger

• Locking workpieces in machine jigs or fixture assemblies.
• Locating parts in automated assembly or inspection equipment.
• Securing removable modules or plates.
• Indexing mechanisms in manufacturing lines.
• Applications in tool rooms, press‑tool setups or assembly stations exposed to harsher environments.
