Abstract: A lock plug comprising a top end having a key way etched out of a solid wall, the key way leading to an interior of the lock plug housing a locking mechanism; and, a break away wall bordering a cavity carved out from the solid wall on a side of the key way, the break away wall forming a side of the key way. The locking mechanism in a lock plug usually employs the wafer technology and in this case, the interior of the lock plug includes a wafer cavity having wafers designed according to a particular key code.

Abstract: The present invention provides a latch assembly of the type commonly used on commercial vehicles which is simple to manufacture and has few parts. The latch assembly secures a closure element, or striker, in either of two secure positions by means of independently operable dual linear latch bolts and may be closed when the locking mechanism is in a locked position, to facilitate ease of operation and to prevent damage to the latch. The latch bolts are releasable by operation of a remotely located handle actuated rotary latch mechanism.

Abstract: A threaded fastener (1) is disclosed for anchoring into a substrate comprising a core portion (2) having at least one helical continuous thread provided along a substantial portion of the length of the core, in which the helical thread has a substantially V-shaped cross section defining two flanks (4a, 4b) which subtend an angle of between substantially 60° and 90°, and the thread has a helix angle of between approximately 20° and 45°. The crest of the thread may be flattened, and the fastener (1) is especially suited to anchoring to a masonry substrate.
