What is a Bulkhead Nut?

A bulkhead nut is used to secure a threaded bulkhead fitting through a panel or bracket. The fitting passes through the mounting hole and the nut is tightened from the opposite side, clamping the fitting securely against the panel.

Choosing the Correct Bulkhead Nut

The thread of the bulkhead nut must match the mounting thread of the bulkhead fitting. Check both the thread diameter and pitch before ordering, as similar diameter threads may use different pitches.

Frequently Asked Questions

What are metric bulkhead nuts used for?
Metric bulkhead nuts are used to secure compatible threaded bulkhead fittings through panels, brackets and firewalls. The nut threads onto the fitting from the opposite side of the panel and clamps it securely in position.
What metric thread sizes are available?
The stainless steel metric bulkhead nuts are available in M10 x 1.00, M12 x 1.00 and M16 x 1.5 thread sizes.
How do I choose the correct bulkhead nut?
Match the internal thread of the nut to the external mounting thread of your bulkhead fitting. Both the thread diameter and pitch must match.
What are the bulkhead nuts made from?
They are precision machined from stainless steel for excellent strength, durability and corrosion resistance.
Does the bulkhead nut seal the fluid connection?
No. The bulkhead nut mechanically secures the fitting to the panel or bracket. The fluid connection is sealed by the corresponding fitting and its specified sealing method.
Can I use a different thread pitch if the diameter is the same?
No. The thread diameter and pitch must both match the bulkhead fitting. For example, an M12 nut with a different thread pitch will not correctly fit an M12 x 1.00 bulkhead thread.
