SCREWS LISTED INDIVIDUALLY These are genuine Crosman screws. Pan head screws are measured from the bottom of the head to the tip of the screw. Flat head are measured by the total length.

 The TRIGGER FRAME SCREWS are available in two lengths. The longer one is 7/16", the shorter is 9/32. These have a combo-drive head as shown in the photo above. These work best with a square #2 (S2) driver but a slotted screwdriver will also work.

 The REAR BREECH SCREWS are available in two lengths. The longer one is 13/16" and fits plastic breeches on models like 1377, 1322, 2240, 2250 and 2260. The shorter one is for steel breeches. The longer screw will interfere with the hammer spring if used with a steel breech, the shorter one must be used.  

 The INNER BREECH SCREW inner breech screw fits a .050" hex wrench.
