A nut for joining fluid conduits in a joint assembly includes a nut body having an inner body surface forming a through-bore, for supporting a first fluid conduit and a second fluid conduit. Internal threads upon the inner body surface advance in a helical path around a nut center axis between a thread origin, and a thread terminus that is located between first and second axial end faces of the nut body. At least one of the thread terminus and the thread origin is located within an increased thickness region formed by a varied radial thickness of the nut. The nut has a reduced risk of cracking in service.

A screw includes a head having and a stem with spaced apart threads. The thread of the thread of the screw includes flat spots and sloped section, and is sized, such that it can securing attach through a hole in the pegboard without damaging the hole despite the thread being wider than the hole.

The present invention relates to an integrated bracket for fixing a sprinkler reducer, and more particularly, to an integrated bracket for fixing a sprinkler reducer, in which left and right portions of a bar-shaped steel frame structure for a sprinkler bracket are vertically bent, tightening/coupling parts are provided at two opposite ends of the steel frame structure, and a fixing unit having a new structure and serving as a middle bracket is integrated with a central portion of the steel frame structure, such that the single bar-shaped steel frame structure may perform a function of fixing the sprinkler reducer and coupling a ceiling steel frame.

A structure includes a first body member including a first interfacing side edge and a first interconnecting component at the first interfacing side edge and a second body member identical to the first body member, the second body member including a second interfacing side edge and a second interconnecting component at the second interfacing side edge. The first interconnecting component engages with the second interconnecting component to secure the first body member and the second body member together.

A thermal concrete wing nut anchor includes a screw having an external thread, and a wing nut mounted on the screw. The screw has a first end provided with an enlarged stop flange, and a second end provided with a drilling tip. The stop flange is provided with a driving head. The wing nut is made of a metal sheet plate which is formed integrally by pressing. The wing nut has a middle provided with a first ear and at least one second ear. The wing nut has an internal thread extending through the first ear and the at least one second ear. The external thread of the screw is screwed through the internal thread of the wing nut.

A wing nut may include a body having a first part extending from a first end surface to a parting line and a second part extending from the parting line to a second end surface. A passage may axially extend through the body, the passage defining an interior surface of the body. An internal threaded section may be formed on an interior surface of the first part. An internal shoulder may be formed on the interior surface of the second part. A stress relief may be formed on the interior surface of the second part between the internal shoulder and the parting line. A rib may extend inward from the interior surface of the second part, the rib being intermediate the stress relief and the internal threaded section. At least one lug may extend radially from the exterior surface of the body.

A mounting system for securely mounting a component, comprising: a mounting platform having a support surface with plurality of mounting holes extending therethrough; a mounting device for securing the component to the mounting platform, the mounting device comprising: a mounting plate with a planar surface facing in a first direction and a stud extending in a second direction away from the first direction, the stud being configured to be inserted through the mounting holes; an adhesive secured to the planar surface and having an engagement surface for adhering to a surface of the component; a fastening device for releasably engaging a portion of the stud inserted through one of the mounting holes to releasably secure the mounting device to the mounting plate.
