An aluminum alloy according to the present invention includes 1.2% by mass to 4.0% by mass of copper, 4.0% by mass to 14.0% by mass of zinc, 0.5% by mass to 4.0% by mass of magnesium, 0.01% or less of silicon, and 0.01% or less of iron, with the balance containing aluminum and inevitable impurities, and has an average equivalent circle crystal grain size of 500 nm or less.

An assembly for a turbomachine turbine includes at least one ring sector made of CMC material and a support casing including an upstream flange and a downstream flange between which each ring sector is disposed, each ring sector including a base that has a radially external face from which radially extend two lugs, the lugs of each ring sector being retained between the two flanges of the support casing by axial pins each engaged in one of the flanges of the ring support casing and in the lug of the ring sector facing said flange, the assembly further including, for each ring sector, at least one radial retaining pin screwed into the support casing and coming to radially bear against a lug of the at least one ring sector to retain it in position, and anti-rotation system for rotationally locking the radial retaining pin.

A joint device for screw and nut includes a first body and a second body. The first body is provided with a plurality of first internal threads, of first external threads, and a first protrusion. The first protrusion is extended with a first engaging portion. The second body is provided with a plurality of second internal threads, of second external threads, and a second protrusion. The second protrusion is extended with a second engaging portion, such that the first protrusion and the second protrusion can be engaged with each other. When in a joining status, the first engaging portion and the second engaging portion are engaged with each other, such that the first body and the second body are folded up and around the screw. The nut can therefore screw up the first body and the second body correspondingly.

A bracket for hanging an item on a wall is disclosed. The bracket has one or more bracket apertures which are used to mount the bracket to the hanging item. The hanging item could be an item like a picture or a shelf. The bracket has a mounting aperture which is used to mount the hanging item on a nail or a screw. Adjacent to the mounting aperture is a pinhole having a set screw. To use the bracket the user unthreads the set screw from the pinhole opening. The user places the hanging item in its desired location on the wall and pushes the item against the wall so that the set screw marks a spot on the wall where the user should place a nail or a screw for hanging the item.

A hardware component imitating a nut/bolt/washer connection for structural members includes a base portion with a disc-shaped base plate and a cylindrical member including an outer surface in the shape of a hex nut. The disc-shaped base plate extends radially to the cylindrical member and imitates a washer. The disc-shaped base plate includes a first opening having a first diameter and the cylindrical member includes a second opening having a second diameter, where the first and second openings are concentric and said second diameter is larger diameter than said first diameter. The first opening is sized to receive therethrough a shaft of a mounting device, and the second opening is sized to receive therein a head of said mounting device.
