locking bolts in patio door lock

[mrcrow]

i have attached a pic to show the adjustable locking bolts on my locks

the shorter is just a bit too short and falls out..
the longer one is fine and has more thread to make the adjustments greater...
i need to get a couple or more to make the doors..(2) more secure
any advice on where i might get them...
the short one is 27mm from under the head to the end
and the longer one 32mm..which is about right considering the extra threads..
much obliged in advance

thanks for the post masona
i dont have a digi cam yet but the lock is set into the door with protruding key points on each side and little black plastic levers which engage the locking mechanism when the door is closed against the striker plate and released by a small plunger which is pushed in...
