Vibrant Threaded Hex Bolt capping Oxygen Sens Bung Mild Steel M18x1.5 thread Bulk Pack of 100 pcs.

If you're fabricating an exhaust system or modifying an existing one, you'll often end up with extra O2 sensor bungs that need to be plugged. These hex bolt plugs from Vibrant are designed specifically for that job. They feature an M18 x 1.5 thread size, which is common on many exhaust systems, and they're built to make installation straightforward without damaging the threads in your bung.

These plugs are made from zinc-plated mild steel. This material choice helps prevent thread damage during both hot and cold cycles, which is important when you're working with exhaust components that experience significant temperature changes. Having a bulk pack of 100 means you'll have plenty on hand for multiple projects or for stocking your shop. The hex head design allows you to easily tighten or remove them with a standard wrench or socket.
