HARFINGTON Push Fit Ball Nose Spring Plunger 3pcs M12x1.5 Carbon Steel

Description

Product Overview

The HARFINGTON 3‑piece Push Fit Ball Nose Spring Plunger is engineered for precision indexing and reliable positioning in a wide range of industrial applications. Each plunger features a robust M12x1.5 carbon steel thread that delivers high hardness, excellent wear resistance, and long‑term durability even in demanding environments. The 6 mm pin diameter provides a compact yet strong engagement point, while the self‑locking mechanism ensures the plunger remains securely in place once set, eliminating unwanted movement during operation. The surface is blackened to protect against corrosion, extending service life and maintaining a professional appearance. With a total length of 20 mm for the threaded section, the plunger offers fine‑tuning capability, allowing users to adjust the insertion depth with high accuracy. The lightweight construction, measuring just 4.59 oz, makes the set easy to carry and handle on the shop floor, while the package dimensions of 4.06 × 3.46 × 1.1 inches provide convenient storage.

Usage

Designed for versatility, this spring plunger set excels in a variety of settings, from heavy‑duty manufacturing lines to small‑scale workshop projects. It is particularly well‑suited for machinery that requires precise stop positions, such as CNC routers, stamping presses, and assembly jigs. The push‑fit ball nose design enables rapid installation and removal without the need for additional tools, making it ideal for applications where downtime must be minimized. Engineers and technicians appreciate the ability to quickly locate and fix mechanical elements, whether they are aligning shafts, securing brackets, or establishing reference points for repeatable processes. The plunger’s self‑locking feature provides confidence in high‑vibration environments, ensuring that the set position remains stable throughout operation. Additionally, the compact size allows integration into tight spaces where larger locking mechanisms would be impractical, expanding its usefulness across a broad spectrum of equipment.

FAQ

What size threads does this plunger use?

The plunger uses an M12x1.5 thread, which is a common size for industrial equipment and provides a balance of strength and fine adjustment capability.

Can the plunger be used in high‑temperature environments?

Yes, the carbon steel construction can tolerate elevated temperatures typical of most machining and manufacturing processes, though extreme heat beyond the material’s rating should be avoided.

How does the self‑locking mechanism work?

When the knob is turned to insert the pin, the ball nose expands slightly, creating friction that locks the plunger in place. Reversing the knob releases the tension, allowing easy removal.

Is the plunger compatible with existing equipment?

The M12x1.5 thread is a standard size, making the plunger compatible with a wide range of machines and fixtures that accept this thread specification.

What warranty does HARFINGTON provide?

HARFINGTON offers a limited one‑year warranty covering manufacturing defects, backed by dedicated technical support to assist with installation and troubleshooting.
