Crosman Breech Screw size
The Crosman Breech Screw is a tiny hex head screw that holds the breech to the tube on Crosman airgun models 2240, 2250, 1740, 1322, 1377, 2300, and 2400.

There are a few options for replacing the Crosman Breech Screw if it is lost or stripped. One option is to purchase a custom breech screw from eBay or another airgun parts retailer. These custom screws may feature a different type of head, such as a slotted or Torx head, which can provide more torque and reduce the likelihood of stripping. Another option is to slice a thin groove into the top of the hex screw with a Dremel tool, allowing it to be turned with a flat-head screwdriver.
It is important to note that not all replacement screws are created equal. Some aftermarket screws may be incorrectly threaded and can strip out and damage the main tube of the airgun. It is recommended to use a Crosman OEM replacement screw or a custom screw from a reputable source.
For those in Canada, local gun shops may be a good source for replacement screws, as the 4-48 thread size is common for scope mounts on rifles. However, it is always a good idea to remove the original screw and confirm the correct size before purchasing a replacement.
