A guide for drilling holes into broken threaded fasteners includes an oblong bar having a stepped slot along its length and a drill guide at one end. Securing sliders travel along the stepped slot and are secured to a structure to be repaired by threaded fasteners through the sliders. Once secured with the drill guide aligned over the broken threaded fastener (possibly with the assistance of an optical sighting device to mark the central axis of the drill guide), the operator drills through the drill guide and into the broken fastener. The tool is removed and the broken fastener can be extracted by various means.

Devices and methods for stabilizing a structural component are provided. The devices may include a main body component, a pair of opposed stabilization feet engageable with opposed regions of the structural component, a pair of coaxially disposed and reciprocal rectilinearly movable support shafts coupling the stabilization feet to the main body component, and an actuator assembly for rectilinearly moving the support shafts opposite to one another which in turn moves the stabilization feet between retracted and extended positions relative to the main body component. In use, the device may be positioned between opposed flanges of a structural component so as to stabilize the component and facilitate automated assembly processes.

A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

A fastener removal aid device for removing a self-locking fastener having a pin with a head and a collar, such as a Hi-Lok fastener, that includes at least one drill opening to receive and position a drill bit and a fastener opening for receiving at least part of the fastener. The fastener opening is designed to fit over either the collar or the pin, and the drill opening then may be centered in axial alignment with the pin, and the drill bit may then drill into either a threaded shaft end or head end of the fastener. Alternatively, the drill opening may be positioned on the sides of the fastener removal aid device to laterally break the fastener, or may also be positioned off-center to drill axially into the collar when the fastener removal aid device is positioned over the collar of the fastener and break the collar.

Embodiments of the apparatus relate to a template used to assist in the removal of broken bolts from an intake manifold mounting fasteners. The apparatus includes a template having a plurality of apertures. When the template is used with a cylinder head, one or more of the apertures is designated as an insertion aperture and one or more of the apertures is designated as a connection apertures. Insertion apertures align with bolt holes of the cylinder head containing broken bolts, and connection apertures align with empty bolt holes of the cylinder head that may be used to secure the template to the cylinder head. The template is used to guide a drill bit or other tools through the insertion apertures as the drill bit or other tool performs work to remove a broken bolt within the cylinder head.
