A bracket assembly for use in constructing a support frame. The bracket assembly has an inner support sleeve section and at least one support arm that is attached to the inner sleeve support section, wherein the support arm is attached to the inner support sleeve section without the use of additional fasteners. The invention also is directed towards kits and methods that include the bracket assembly.

A cover assembly generally includes a lock channel, flush mounted panels, a fastener, and a nut. Advantageously, the cover and cover systems are corrosion resistant and/or high strength, comprised of removable panels, offer easy installation and access, may be high strength fiber reinforced plastic, offer life cycle cost savings, may be compression sealed, have long relatively maintenance-free life, and/or are customizable.

A boat hull has one or more track systems integral with a main body of the boat hull, each track system having a longitudinally extending channel comprising: a longitudinally extending channel body; and a longitudinally extending channel opening in communication with the channel body, wherein the channel body is wider in cross-section than the channel opening, the channel body is adapted to receive a fastener which has a portion that is wider in cross section than the channel opening, thereby preventing the fastener from being withdrawn from the channel body through the channel opening, and wherein the fastener can be selectively secured to the track system at a selected longitudinal position. The track systems can be used for mounting boat hull structural parts and other parts and accessories.

A bearing clip for joining a truss to a bearing material is disclosed. The bearing clip includes a base portion, a vertical portion, and at least one wing. The base portion includes a back end, sides adjacent to the back end and a bottom surface. The vertical portion extends from the back end of the base portion in a first direction away from the bottom surface. The at least one wing extends from a side of the base portion at an obtuse angle and at least partially in the first direction.

The present disclosure provides an insert of a fastening system. The insert includes (a) a flange, (b) a sidewall extending from the flange and defining a first through-hole, (c) a nut including a first end and a second end and defining a second through-hole, wherein the second end of the nut comprises two or more gripping fingers extending longitudinally from the first end of the nut and separated by two or more slots, and wherein the two or more gripping fingers are flexible in a radial direction and biased to converge inward such that the second through-hole is tapered from the first end of the nut to the second end of the nut, and (d) a stopper coupled to an interior surface of the sidewall and positioned between the first end of the nut and the flange.

A connection assembly for robot joints, including: a first joint provided with a first connection end, where a connection base is provided on the first connection end, and the connection base is provided with a first connection protrusion extending radially outward; a second joint provided with a second connection end, where a connector is provided on the second connection end, and an external thread is provided on an outer circumference of the connector; and a connection nut adapted to be rotatably sleeved on the connector, where an internal thread is provided on an inner circumference of the connection nut, a second connection protrusion extending radially inward is formed at an end of the connection nut facing the first connection end, and the second connection protrusion is sleeved on a radial outer side of the connection base, such that the first connection protrusion is accommodated in a space, facing the second joint, formed by the second connection protrusion. The problem of complicated assembly and disassembly of joints of a collaborative robot is solved.

A wall attachment device for securing a handrail to a supporting wall, the handrail having a first end and a second end, at least one of the first and second ends being hollow and including an inner connecting member extending radially inwardly within the corresponding end, the device comprising: a body sized and shaped to be received in the corresponding end, the body including a planar rear face adapted to be positioned against the supporting wall, a front face opposite the rear face and a lateral face, the body further having at least one fastener opening to receive a fastener for securing the body to the supporting wall; and an outer connecting member extending radially outwardly from the lateral face for securely engaging the inner connecting member of the handrail to thereby attach the corresponding one of the first and second ends of the handrail to the supporting wall.

A disclosed tolerance compensator system reduces or avoids bending of components when the components are fastened to each other, thereby increasing the reliability of the components. The limited number of parts of the tolerance compensator system simplifies manufacturing and reduces costs. A disclosed method for fastening components together using the tolerance compensator system reduces or avoids bending of components, increases the reliability of the components, reduces fastening times, and simplifies fastening procedures.

An adapter clip includes a first portion configured to fit within an engine clip or an engine clamp, a second portion including an annular portion, the annular portion being configured to fit around an engine component, and a web portion connected to the annular portion and the first portion. A diameter of the first portion differs from a diameter of the annular portion.
