M6 Counterbore Steel Bung

Our Metric Counterbore Weld-In Bungs are precision-machined from 1018 cold rolled mild steel, designed for clean and professional fabrication work. Each bung is counterbored to accept an M6 socket head cap screw (Allen bolt), allowing the bolt head to sit flush with the top surface. This design not only provides a secure fit but also lets you weld right up to the bolt head, creating a smooth, finished appearance without exposed edges.

Perfect for metric fabrication projects, these bungs are available in two lengths to match your build requirements. With a 5/8" outer diameter and durable steel construction, they are ideal for chassis mounts, custom brackets, or any application where a strong and clean mounting solution is needed.
