RETENTION AND ANTI-ROATATION FOR BULKHEAD FITTINGS

摘要

A bulkhead fitting has a partially assembled configuration and a fully assembled configuration on a bulkhead. The bulkhead includes an interior surface that define a hole. The bulkhead fitting includes a fitting body having a head portion and a shank portion. The shank portion includes a threaded portion, a relief portion, and a locking portion. The locking portion includes a tapered locking surface and a cylindrical locking surface. The locking surfaces prevent rotation of the fitting body and retain the fitting body in the interior surface when the fitting is in its fully assembled position and during assembly.
