Lockable nut system
First Claim
1. A lockable nut system for threaded steel bar having a non-circular cross-sectional shape with at least one planar side wall, said lockable nut system comprising:
- a screw threaded nut rotatably engageable on said threaded steel bar; and
a locking member comprising a generally disc-like body slidably engageable on said threaded steel bar, said locking member being adapted in use to resist rotation about said bar by engagement of at least one inner side wall of said locking member with a respective side wall of said bar, said locking system characterized in that said nut and said locking member are axially engageable by one or more spigot and socket formations on respective adjacent ends of said nut and said locking member, wherein said one or more spigot formations comprise at least one nut engaging element projecting axially from said locking member; and
said one or more socket formations comprise at least one recess in said nut and, at least one actuating element on said locking member being deformable from a first to a second position, in use, urging said at least one nut engaging element into engagement with said at least one recess in the nut, said nut and said locking member being axially engageable whereby in use said locking member resists rotation in at least one direction of said nut on said bar.

Abstract
A lockable nut system for use with threaded steel bar which includes a screw threaded nut for engagement with the threaded steel bar and a locking member which is slidably engageable with the bar. The locking member is adapted to resist rotation about the bar and is also axially engageable with the nut to prevent rotation of the nut. The locking member has one or more fingers to engage the nut with an end of the finger being displaced to engage the nut as a result of deformation of a finger actuating tab or a dished body of the locking member. The locking member may engage the bar by displacement of an end of at least one tongue as a result of deformation of a tongue actuating tab during compression between the nut and a second structure.
