Abstract
The present invention provides a tubular keyed cam lock with increased resistance to tampering. The cam lock has a rear screw which attaches the cam to the rotatable cam of the lock, thereby increasing the strength of the lock by preventing the lock from being pried off. The lock includes a plug body with a key entering end and a cam actuating end, a plurality of spring biased pin tumblers engaging the key when the key is inserted into the plug body and a lock housing within which the plug body is rotatably positioned. The lock housing has at least one limit stop disposed thereon. As discussed above, the cam-actuating end of the plug body is connected with a screw to a metal stop plate.
