HARFINGTON Ball Point Spring Plungers 30pcs Brass Set 2-3-4mm

Description

Product Overview

The HARFINGTON Ball Point Spring Plungers are engineered to deliver exceptional precision and reliability for a wide range of mechanical and woodworking applications. Crafted from high-quality brass, each plunger offers superior corrosion resistance, ensuring a long service life even in demanding environments. The set includes thirty individual plungers in three standardized diameters—2 mm, 3 mm, and 4 mm—providing versatile options for positioning, indexing, locking, and lifting tasks. With body lengths of 3 mm, 4 mm, and 5 mm respectively, the overall dimensions range from 3.4 mm to 6 mm in length, allowing seamless integration into tight spaces and intricate assemblies. The precision‑cast and polished beads feature a tolerance of ±0.05 mm, guaranteeing consistent performance and repeatable results across multiple installations. Designed for ease of use, the plungers employ a simple press‑in mechanism that eliminates the need for additional tools or complex adjustments, making them ideal for both seasoned technicians and hobbyist makers.

Usage

These spring plungers are indispensable in a variety of settings, from industrial machinery to household furniture. In cabinet construction, the 2 mm and 3 mm plungers provide discreet yet secure latch points for drawer fronts, ensuring smooth operation without visible hardware. For larger furniture pieces, the 4 mm plungers deliver the necessary holding force to support heavier doors and panels. In automation equipment, the precise positioning capability enables accurate alignment of moving parts, reducing wear and extending the lifespan of the overall system. The robust brass construction also makes the plungers suitable for high‑temperature environments, such as metalworking tools and CNC machines, where plastic components would quickly degrade. Whether you are assembling a custom workbench, repairing a vintage appliance, or prototyping a new mechanical device, the HARFINGTON spring plungers offer a reliable solution that adapts to diverse mechanical challenges.
