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 tie nut of a formwork tie for connecting two formwork elements is secured on a tie rod to prevent inadvertent rotation by way of a form fit coupling that can be axially made to engage therewith.

A fastener system for securing a component to a structure is provided. The system includes a pin portion and a clip portion. The pin portion has a head and a shaft. The clip portion has a head engagement flange and a retainer flange configured to receive a fastener that extends along a first axis. The clip portion and the pin portion are configured for engagement with one another in an engaged position, and in the engaged position the pin portion shaft extends along a second axis non-parallel to the first axis.

A locking device (11), e.g. a lock washer, for use with a screw threaded fastener (71), said locking device comprising at least a first disc-like body (12) comprising an annular portion (13) with at least one aperture (15) therein and a central through-hole (14) e.g. a washer having notches (15) open to the outer periphery and at least one further body (25) held in said one aperture (15). The further body may be shim (22) also having a central hole (24) and at least one tab (25) which extends through the notch (15) and has an end portion which juts above adjacent surface of the washer to engage an adjacent surface on the fastener when compressed, on tightening of the fastener deflects within the void of the aperture in which it is located under the influence of the tightening of the engaging surface such that under any tendency to loosen, the tab jams against the opposing surfaces and resist loosening of the fastener.
