A lockout tool for an air cycle machine includes a lockout tool body threaded section, a lockout tool body end section, and a lockout tool body conical tip. The lockout tool body threaded section is operable to engage a threaded port of the air cycle machine that is proximate to a shaft of the air cycle machine. The lockout tool body end section includes a rotation interface operable to receive a rotational force to control engagement of the lockout tool body threaded section with the threaded port. The lockout tool body conical tip is operable to engage the shaft of the air cycle machine to prevent rotation of the shaft.

A durable captive bolt assembly for use with subterranean utility boxes is described. The disclosed bolt assembly includes a fastener, a conical spring, a rigid washer, a deformable washer, and a bushing. The point and threads of the fastener are designed to clear debris from an internally threaded nut and reduce or eliminate cross threading, galling, and electrolysis.

Embodiments of the disclosure relate to an apparatus that disengages a tool and indicates undesired contact. More specifically, the embodiments of the disclosure relate to a fastener that limits over insertion, indicates over insertion, and limits undesired contact of that fastener with a surface. Further, the apparatus can limit damage to an underlying component such as a circuit board. The apparatus has a shank having a cavity extending through the shank. Additionally, the shank has a recess for installation by a tool. A slider is positioned within the shank wherein the slider can limit engagement with the recess and indicate a condition.

A system for mounting a wire screen panel to a frame for screening particulate materials. The frame has a stringer with a ferrule defined therein. The system comprises a screen panel having a first plurality of wires and a second plurality of wires disposed. The screen panel has a first side and a second side disposed opposite from the first side. The screen panel has a first end and a second end disposed opposite from the first end. A plate is disposed along at least a portion of the length of the first side of the screen panel. A fastener having a shaft and a head portion is configured and arranged to extend adjacent to the plate and to engage with a bushing disposed in the ferrule in the stringer. The head portion of the fastener engages with the plate on the side of the plate opposite the stringer such that the screen panel is fixed in position relative to the frame.

A fixing element for components of an assembly, comprising a rod which is formed by a cylindrical shaft and an end, the rod being a metal component which is at least partially surface-treated by means of anode oxidation and coated over at least a portion of the cylindrical shaft with a lubricating coating. Such a fixing element enables the electrical continuity to be ensured with the components during mounting with moderate interference in the assembly.
