A conveyor module (10) includes a module body (12) with a pair of first link ends (14) extending in a first direction of travel and a second link end (16) extending in a second direction of travel opposite the first direction. Each of the first and second link ends (14, 16) has a transverse opening (15, 17) therethrough. At least one of the first link ends (14) has a first mating portion (30). A pin (20) is configured to be received in the first transverse openings (15) of the module body (12). The pin (20) has a shaft (22) and a lever (28) affixed at a first end (24) of the shaft (22). The lever (28) has a second mating portion configured to be rotatably coupled with the first mating portion (30) of the module body (12), thereby preventing transverse movement of the shaft (22).
