Pet nail caps cover pets' nails to prevent scratches on surfaces (e.g., hardwood and tiled flooring) and avoid injuries to themselves and others (e.g., pets' eyes and ears, human extremities) while not compromising pet's mobility but rather improving it. The treads on the caps' tips increase the coefficient of friction between the caps (i.e., individual pet's nails) and the hard-surface flooring improving traction and overall pet's mobility. Internal spirals allow the caps to twist onto pets' nails and stay securely attached. A rubber-like material of construction (e.g., thermoplastic elastomers, thermoplastic polyurethane) provides for cap's flexibility and durability.

A fastening structure includes a blind rivet and a nut. The blind rivet includes a rivet body having a hollow sleeve, a rivet head at the end of the sleeve and a through-hole; and a mandrel having an elongated stem and a mandrel head. The nut is positioned around the sleeve side end of the rivet body and the mandrel head and abuts one of the workpieces. The end portion of the sleeve is enlarged by the mandrel head and is embedded in the internal screw threads of the nut. The workpieces are thus fastened between the nut and the rivet head.

A firearm barrel nut assembly including barrel nut, generally cylindrical in shape with a threaded central bore, and an externally threaded locknut which is used in conjunction with the barrel nut to secure a barrel to a firearm upper receiver. The barrel nut has an integral bushing on its exterior constructed to support either the gas tube or piston of the host firearm's operating system. The barrel nut is configured so that it may be independently and non-rotationally held within a vice or other fixture during installation of the barrel and while the locknut is tightened to a preset torque to hold the barrel in place while the barrel nut is independent of the torque applied to the locknut to properly secure the barrel to the upper receiver.

A male fastener, female fastener, and a plunger that is adapted to secure the female fastener to the male fastener, and to prevent unwanted loosening of the female fastener from the male fastener. The male fastener includes a shaft that may optionally include a plurality of protruding elements that extend outwardly from an external surface of the shaft. The protruding elements may be radially positioned in rows around a circumference of the shaft, to create a channel between the rows of protruding elements. The channel is adapted to receive a corresponding thread located within an aperture of the female fastener. The plunger is adapted to be inserted into a trench located between a set of protruding elements (or into multiple trenches located between multiple protruding elements). The plunger prevents the female fastener from rotating around the shaft in a direction towards the bottom portion of the male fastener.

A standoff assembly for separating a first component from a second component from one another a predetermined distance includes a standoff having a predetermined length defined between a first end and a second end, and an anti-rotational structure formed at the first end. The anti-rotational structure is configured to be inserted into a corresponding opening formed in the first component. The standoff assembly further includes a first fastener to secure the first component to the first end of the standoff and a second fastener to secure the second component to the second end of the standoff. A method for separating a first component from a second component is further disclosed.
