Ball Point Spring Plunger HARFINGTON 20pcs 6x7mm 304 Stainless Steel

Description

Product Overview

The HARFINGTON ball point spring plunger is engineered for high‑precision applications where reliable positioning is essential. Each plunger measures 6mm in diameter and 7mm in length, with an overall length of 8.7mm, delivering a consistent 15N of elastic force. Constructed from 304 stainless steel, the plunger offers excellent corrosion resistance, heat tolerance, and strength, ensuring long‑term performance even in demanding environments.

Precision casting and polishing give the bead a smooth surface finish (Ra 3.2) that reduces friction and wear during repeated cycles. The compact design allows easy integration into tight spaces such as cabinet hinges, drawer slides, and automation mechanisms. The plunger’s elastic range and surface finish make it suitable for both static locking and dynamic positioning tasks.

With a package of 20 pieces, the set provides ample inventory for production runs, maintenance kits, or hobbyist projects. The simple press‑in installation eliminates the need for tools, reducing assembly time and minimizing the risk of damage during installation.

Designed for versatility, these plungers are compatible with a wide range of mechanical devices, from furniture hardware to industrial automation components, delivering consistent performance across diverse applications.

Usage

These spring plungers excel in environments where precise alignment and secure locking are required. In furniture manufacturing, they are used to create smooth‑operating drawer mechanisms and secure cabinet doors, providing a tactile click that signals proper closure.

In automation machinery, the plungers serve as indexing pins that hold moving parts in exact positions during assembly or operation, ensuring repeatable accuracy. Their compact size allows them to be incorporated into robotic end‑effectors, tool changers, and custom fixtures.

For hobbyists and DIY enthusiasts, the pluggable design makes them ideal for custom projects such as 3‑D‑printed assemblies, model railways, and prototype mechanisms where space is limited but reliability cannot be compromised.
