Are you sure you want 8 ft lengths?

For the lowest shipping cost, we suggest 6 ft or shorter when possible. 8 ft lengths add substantially to UPS and FedEx shipping charges.

Full lengths are quoted by phone

We only sell short lengths online. For full mill lengths of 20–24 ft, please call us for a quote and we'll price the pipe and freight together.

5/16"-18 x 5/16"
