Abstract: An access cover assembly for machines, equipment, mechanical assemblies and like apparatus is configured to be mounted or attached to an exterior housing or casing of the apparatus to cover an access port or opening in the housing that is used for gaining access to the interior of the apparatus. The access cover assembly includes a cover plate and a removable, self-locking plug that can be quickly and easily installed and removed from the cover plate. The cover plate has a threaded access opening and the self-locking plug includes a threaded shaft that engages with the threaded access opening when secured to the cover plate. The self-locking plug incorporates a lock ring that inhibits unintended rotation and loosening of the self-locking plug when assembled to the cover plate.

Abstract: A precision adjustable length rod end assembly is disclosed and provides a fastener for mechanical assemblies that eliminates the need for a separate secondary locking device. The device includes a connecting rod, an end connector or rod end, and a lock nut assembly. The end connector threadably engages the connecting rod. The lock nut assembly engages both the end connector and the connecting rod. The threaded engagement between the end connector and the connecting rod enables the rod-end assembly to be adjusted to a precise working length (e.g., as measured along the central longitudinal axis). The lock nut assembly maintains the precision-adjusted working length of the rod-end assembly even when the rod-end assembly is exposed to harsh operating conditions, such as exposure to extreme vibrations.
