Professional Applications & Engineering Value

This 3/16" Hex 4-40 Jack Screw is engineered to address common challenges in electronics, machinery, and precision equipment assembly. The Zinc Yellow-Chromate plated 12L14 steel construction combats corrosion and oxidation, critical in humid or industrial settings where component failure can lead to downtime. Its Class 2A/2B thread fit ensures precise mating with corresponding threaded parts, minimizing the risk of strip-out and enhancing connection integrity in threaded standoff applications. The inclusion of a lock washer and flat washers provides added vibration resistance, making it ideal for securing panels, PCBs, or mechanical linkages that experience dynamic loads. By offering a male-female thread design in a single, compliant unit, it simplifies inventory and speeds up installation, reducing labor costs and improving overall assembly reliability.
