Aspects of the disclosure are directed to a bolt comprising: a body having a head, a circumferential sidewall, a central bore extending at least a portion of a length of the bolt, and a plurality of slots extending through the sidewall from the bore, a plurality of positioning arms at least partially located within an interior of the bolt, and a screw seated within the head, where a position of the screw within the head controls an extent to which the plurality of the positioning arms are extended through the sidewall.

A sealant application apparatus includes a seal gun, a distance meter, a moving mechanism and a controller. The seal gun has a nozzle for discharging sealant toward a fastener. The distance meter is fixed to the nozzle. The distance meter measures a distance from a measurement position to a surface of the sealant. The moving mechanism moves the seal gun relatively to the fastener. The controller controls the moving mechanism and the seal gun. The sealant is started to be discharged out from the seal gun in a state where the nozzle has been positioned to cover the fastener at a position away from a surface of the object by a predetermined distance. Subsequently, the sealant is applied to the fastener under a sealant application condition according to the distance measured by the distance meter while moving the nozzle away from the surface of the object.

A screw, in particular for housings, has an elongated section provided at least in parts with a thread, and a screw head. A cone-shape section may be arranged between the screw head and the elongated section, wherein the point of the conical section connects to one end of the elongated section, and the underside of the screw head may be arranged opposite the base surface of the conical section, and a groove for accommodating a seal may be provided between the underside of the screw head and the base surface of the conical section.

An equipment mounting system for mounting equipment to a support structure is described. An equipment mounting system including: (i) a mounting plate having defined therein a plate aperture of a particular shape; (ii) a bolt having a shaft portion including a threaded portion and a non-threaded portion that is of a complementary shape that complements the particular shape of the plate aperture; and (iii) a washer having defined therein a scored aperture that includes multiple radially extending scorings. In an assembled configuration of the mounting plate, the bolt and the washer, the plate aperture of the particular shape aligns with the scoring aperture such that both of the plate aperture and the scoring aperture receive the non-threaded portion of the complementary shape, and the particular shape of the mounting plate engages with the complementary shape of the bolt to prevent rotational displacement of the bolt around the mounting plate.

A pass through fitting for a cable or the like comprises a split bolt having a threaded shank and a nut which can be locked on the shank to prevent rotation therebetween. A passageway extends through the split bolt for receiving one or more cables. The fitting would be supported in a structure, such as a boat hull, through which it is desired to run the cable. The fitting may be sealed at the head, against the structure, to be watertight.

A building system that includes a modular panel with side members, at least one of the side members having an associated coupling for hooked connection with a corresponding shaped fixture of an adjacent structure, the coupling and fixture being adapted to be held together by a locking device that, when engaged, acts to lock the structure and the side member together and, when disengaged, allows for play between the panel and structure in order to free the panel from the structure.

The present invention proposes a cap for forming a sealed cavity around one end of a fastener to thereby contain out-gassing and sparking events in the event of a lightning strike to the fastener. The invention also proposes a joint comprising such a cap, and a kit of parts and method for installing such a cap. A cap according to the invention comprises: an inner cap member having an annular base terminating at an edge which surrounds an opening into an air cavity for enclosing the one end of a fastener; and an outer cap member having an annular skirt or flange which extends radially outwardly away from the annular base, the annular skirt or flange and annular base between them defining an annular sealing cavity. The cap also comprises a sealing material inlet comprising an opening in the outer cap member that is in fluid communication with the annular sealing cavity, the opening being arranged to interconnect with a sealing material injection device to provide a flow of curable sealing material from the sealing material inlet into the annular sealing cavity. The outer cap member has an inner surface formed with a first locking feature, and the inner cap member has an outer surface formed with a second locking feature which forms a snap-fit joint with the first locking feature.

A golf club head including a weight mount disposed on the sole, a weight member configured to reside in the weight mount, a compressible member residing between the weight member and the weight mount, wherein the weight member comprises a longitudinal axis about which the weight member is configured to rotate, the weight member comprising projections extending radially outwards from the longitudinal axis, wherein the weight mount comprises circumferential ramps, wherein rotation of the weight member about the longitudinal axis forces the projections along the circumferential ramps, wherein the weight member goes from an unlocked position to a locked position in less than one full turn of the weight member relative to the weight mount, wherein rotation of the weight member compresses the compressible member, wherein the circumferential ramps comprise detents, wherein the projections are configured to reside in the detents when the weight member is in the locked position.

This invention builds up on technical features and on the industry experience with the use of Merlin™ family connectors. In addition to friction, structural means utilized to transfer high torsional loads include dog-clutch teeth and may also include: interlocked thread systems, shear pins, keys and splines, all used in isolation or in arbitrary combinations. Static and fatigue bending load capacities of the connectors remain high, while the axial load capacities may or may not be high, depending on the design requirements. Connectors according to this invention can be built as new, carefully optimized designs. In some cases upgrading existing Merlin™ family connector designs to increase they torque transfer capacities may be also feasible.

A sealant containment assembly for enclosing fasteners disposed within a confined space. The sealant containment assembly includes a first containment member and a second containment member that extend between two surfaces. The first and second containment members each include structure-engaging ends for engaging a structural member and the first and second containment members each include enclosure ends that connect the first and second containment members together to enclose the fasteners within a confined space defined by the first and second containment members, the first and second surfaces, the structural member and the connected enclosure ends. The assembly also includes at least one injection port disposed outside of the confined space but is in communication with at least one distribution port disposed inside the confined space for filling the confined space with sealant, thereby embedding the fasteners in sealant.
