RS PRO M20 Index Plunger, Cam-action, Spring Loaded, 69 mm Long 237-417

RS PRO presents the 237-417 M20 Index Plunger, a cam-action, spring-loaded industrial component designed for precision positioning in machinery and automation environments. The robust engineering integrates a cam-action handle with a spring-loaded mechanism, allowing for rapid withdrawal and locking of the plunger pin. By rotating the lever through 180 degrees, the plunger is withdrawn, while a groove and notch ensure safe and reliable handle positioning during operation.

This index plunger is constructed from high quality blackened steel featuring a nitride plunger or, in some versions, stainless steel with a nickel plated plunger. The lever includes a plastic cover cap (locknut version), providing additional comfort and ergonomic safety for operators in demanding settings. The thread size is M20, offering compatibility with standard industrial fastener systems, and the 69 mm length adapts smoothly to a variety of machine and equipment layouts.

The spring mechanism ensures consistent actuation, making it suitable for frequent positioning and catching tasks within machinery, appliances, and industrial hardware. Applications range from locking and indexing moving parts in manufacturing equipment, to securing setup positions in laboratory and assembly lines, where reliability and repeatability are paramount for safety and workflow efficiency.

Key features include a cam-type handle for quick and easy release, a locking notch for safe lever retraction, and high quality materials for durability. This index plunger is not RoHS-approved and is manufactured in China, according to evidence.
