Abstract: Systems and methods for replaceable thread locking elements are provided. In one embodiment, a threaded fastener device comprises: a first member having a threaded region; a cutout within the ring shaped member that cuts across the threaded region; and a replaceable thread locking element removeably coupled to the ring shaped member within the cutout, the replaceable thread locking element comprising a displacement member coupled to a nipple via an extending member. The nipple is inserted into and orifice within the cutout, the nipple shaped to apply a force against the first member that holds the displacement member within the cutout.

Abstract: A laser block assembly (LBA) gas fill process device with improved cathode electrode connectors. An example device includes a gas fill component that attaches to an LBA under test and electrical connectors that receive a voltage bias from a voltage source and apply the voltage bias to cathodes of the LBA. The electrical connectors include an end having a torsion spring that is sized based on the cathodes of the LBA. Also, the electrical connectors may include a strain relief spring.
