HARFINGTON Push Fit Ball Nose Spring Plunger M12x1.5 Stainless

Description

Product Overview

The HARFINGTON Push Fit Ball Nose Spring Plunger is engineered for precision and durability in demanding industrial environments. Featuring a compact M12x1.5 thread length of 20 mm and a 6 mm pin diameter, this plunger delivers fine‑tuned positioning that meets the exacting standards of modern machinery. Constructed from high‑grade stainless steel, the plunger resists corrosion, wear, and deformation, ensuring a long service life even under continuous exposure to moisture, chemicals, and temperature fluctuations.

Designed with a thin thread profile, the plunger enables users to adjust the insertion depth with exceptional accuracy, facilitating optimal indexing for a wide range of applications. The return knob provides a smooth, tactile feel, allowing quick pull‑out and insertion actions without the need for additional tools. This combination of material quality, precise threading, and ergonomic design makes the plunger an indispensable component for engineers, technicians, and maintenance professionals.

Usage

In industrial equipment, the Push Fit Ball Nose Spring Plunger serves as a reliable locking and positioning element for telescopic lock pins, machine tool fixtures, and adjustable jigs. Its compact size and lightweight construction (approximately 1.41 oz) make it easy to carry and install in confined spaces, such as CNC machine tool housings, robotic arms, and assembly line stations.

The plunger excels in environments where rapid reconfiguration is essential. For example, in a machining workshop, operators can swiftly secure workpieces by inserting the pin, then fine‑adjust the position using the thin thread to achieve the exact alignment required for cutting, drilling, or milling operations. Its stainless steel composition also ensures that the plunger remains functional in humid or oily conditions, reducing downtime caused by rust or corrosion.

Beyond traditional manufacturing, the plunger is suitable for engineering prototypes, research labs, and custom equipment where precise, repeatable positioning is critical. Whether used in a test rig for material testing or as part of a modular fixture system, the plunger provides a dependable solution that enhances productivity and safety.
