Abstract

A connector assembly for an adhesive dispenser is provided and includes a drum fixture seated into a drum containing an adhesive material. The drum fixture is configured for fluid communication with the drum. A hose fixture is connected to the drum fixture and configured for fluid communication with the drum fixture. The hose fixture is configured for insertion and rotation to form the connection with the drum fixture. The hose fixture includes a latch assembly configured to prevent rotation of the hose fixture. A seal member is disposed between the drum fixture and the hose fixture. The seal member is configured to facilitate fluid communication between the drum fixture and the hose fixture. The seal member is configured to prevent leakage of fluid materials between the hose fixture and the drum fixture. The latch assembly requires manual intervention to remove the hose fixture from the drum fixture.

Abstract

First and second components are connected together by a fastener that includes a head and a shank having a bolt portion and a drill portion. The fastener is initially rotated relative to the first and second components such that the drill portion drills a hole through the first and second components. Then, the drive portion of the fastener is removed from the bolt portion of the shank of the fastener, such as by using a removal tool. Lastly, a nut is installed on the bolt portion of the shank of the fastener.
