A bond strength tester unit is provided for testing adhesive bond strength of a nutplate or the like attached to a substrate, such as by adhesive bonded attachment to a blind side of the substrate in substantial alignment with a substrate opening. The nutplate may be constructed according to U.S. Pat. No. 5,013,391, and carries a fastener element such as a threaded nut or the like for subsequent connection with a mating fastener element such as a threaded bolt or the like passed through the substrate opening. The tester unit includes a tool tip having a reaction head for engaging the substrate, in combination with an actuator pin for applying a test force of selected magnitude against the adhesively bonded nutplate. In the event of inadequate bond strength, the actuator pin will separate the nutplate from the substrate.
An adhesive attachment (26) is provided for securely mounting an attachment component (20) such as a threaded stud (20) or the like on the surface of a selected substrate, wherein the adhesive attachment (26) provides an electrically conductive ground path for grounding the attachment component and/or a selected structure mounted thereto to the substrate. In one preferred form, the attachment component is a threaded element (20) such as a stud or nut. Upon mounting of the attachment component on the substrate and subsequent connection of the threaded element to a mating threaded member, e.g., of the selected structure to be mounted onto the attachment component, a conductive ground pin (18) is pressed into electrical contact with the substrate for grounding the attachment component and/or the selected structure mounted thereto.
An adjustable mounting bracket for secure mounting as by adhesive attachment onto an exposed edge of a substrate, wherein the mounting bracket is adapted for quick and easy subsequent mounting of a selected structure such as tubing, wire bundles, etc., relative to the substrate. The adjustable mounting bracket includes a pair of slidably interfitting, generally L-shaped bracket members which cooperatively define a slidably overlying pair of mounting plates and an associated pair of slidably separable clamp jaw plates. The slidably interfitting mounting plates accommodate adjustable spaced-apart separation of the clamp jaw plates to seat firmly against opposed surfaces of the substrate edge, such as mounting onto a rib protruding from the substrate or mounting onto an inner diameter edge of an opening formed in the substrate.

An improved cable tie is provided for securely bundling one or more wires or the like. The cable tie includes a buckle formed by a buckle housing having a double-ended barbed insert mounted therein. The buckle housing defines an anchor slot open at one end for seated reception of a first end of a flexible cable strap, with the barbed insert gripping and retaining the strap therein. A through channel is also formed in the buckle housing and accommodates unidirectional slide-through passage of an opposite or free end of the strap, with the barbed insert gripping and retaining the strap free end against withdrawal relative to the through channel. This flexible strap can be formed from a high strength material such as polyetheretherketone (PEEK) suitable for use in a relatively high temperature environment.
