A protection system includes a mount for attachment to a wear panel of equipment. The mount includes a first portion which engages the wear panel to be protected and a second portion extending from the first portion which engages an adjacent face to be protected. The second portion has a passage which allows sliding movement of a bolt along the passage. A wear part is releasably mounted to the mount and has a first portion that slidingly engages the first portion of the mount and a second portion that engages the second portion of the mount. The second portion of the wear part has a passage arranged to align with the passage through the second portion of the mount when the wear part and the mount are engaged. A bolt extends through the aligned passages to secure the wear part to the mount via a locking member.

A spanner for simultaneously gripping a plurality of fasteners. The spanner includes a body, the body having a plurality of spaced apart fastener grips for simultaneously gripping the plurality of fasteners. The spanner also includes at least one attachment member for attaching the spanner to a structure the fasteners attach to.

A fixing device for fasteners having a polygonal head for the detachable connection of flanges which can be connected to one another and clamped against one another by a screw connection includes a chain which encompasses at least some regions of the lateral surface of the polygonal heads in a form-fitting manner and inhibits the rotation of said fasteners. The chain comprises a plurality of spaced members, each having at least one receptacle, the inner profile of which corresponds to the lateral surface of the polygonal heads. The chain comprises at least one releasable tensioner for detachably joining two ends of the chain. A flexible securing means is provided, which extends circumferentially along the chain, wherein at least two ends of the securing means can be releasably connected to one another.

An assembly comprising: a nut having a cylindrical body with a threaded external surface, an axially extending interior tool socket, and a radially outwardly extending flange at a proximal end of the cylindrical body; a first component including a hollow cylindrical tube with a connector end having a radially inwardly extending shoulder, the radially inwardly extending shoulder abutting the radially outwardly extending flange of the nut in an assembled position; and a second component including an annular hub with a threaded internal surface matching the threaded external surface of the nut, and an annular mounting surface abutting the connector end of the propeller shaft in the assembled position.

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 washer includes a hub and a first lobe connected to the hub. The first lobe includes a first hole. A second lobe is also connected to the hub and includes a second hole. A third lobe is also connected to the hub and includes a third hole. The first lobe extends from the hub at least partially in a first direction opposite the second lobe and the third lobe.

An anti loosening arrangement doer wheel nuts which uses wheel rim with a plurality of studs having external threads to receive fastening nuts, a wheel nut with an internal thread adapted to be secured to said studs a connector adapted to be attached to and connect adjacent nuts said connector including a mechanism to prevent rotation of the nuts. This arrangement does not require a custom stud. In some preferred mechanisms custom nuts may be needed but in other preferred embodiments conventional nuts may be used. The connector prevents rotation of the nuts and so inhibits loosening. The connector is easily seen and is an indication that the wheel nuts are unable to be loosened.

A washer includes a first lobe comprising a first hole, a second lobe comprising a second hole, a third lobe comprising a third hole, and a fourth lobe comprising a fourth hole. A first leg extends from the first lobe to the second lobe, and a second leg extends between the third lobe and the fourth lobe, wherein the second leg is parallel to the first leg. A third leg extends from the first lobe to the third lobe and spaces the first leg from the second leg such that the second lobe is disposed opposite the fourth lobe.

An apparatus (10) for visually indicating a loose wheel nut (57) on a wheel of a motor vehicle has a plurality of wheel nut engaging members (12, 14, 16, 18, 20). Each wheel nut engaging member is rotatable with a respective wheel nut to which it is engaged and has a pointer (26) for indicating a start position of the wheel nut engaging member. Any two adjacent wheel nut engaging members of the plurality are interconnected by an elongate member (28) which is resiliently flexible so as to define an endless configuration of spaced apart but interconnected wheel nut engaging members. In use, any loosening rotation of a first wheel nut (57) will cause the engaging member (12) which engages that wheel nut and its pointer (26) to rotate therewith, thereby providing a visual indication of a loosening of that wheel nut.

A protection system including: a mount (20) adapted to be fixed to a wear panel (11); a wear pad (16); and a locking member; said mount (20) and said wear pad (16) having complementary engagement means (27 to 31 and 68 to 73) adapted to allow relative sliding movement between said mount (20) and said wear pad (11) from a release position to an engaged position; said mount (20) and said wear pad (11) each having an opening or recess (48, 86) therein adapted to receive said locking member, said locking member prevents sliding movement of said wear pad relative to said mount (20); and said mount further and said locking member each having at least one passage (51) adapted to receive therein a bolt (101); and whereby one or more bolts (101) extending through each said at least one passage secure said locking member to said mount.
