These are new custom stainless screws for securing a fixed wood or plastic stock to the AKM rear trunnion’s tang. Making them was an adventure. The Soviets actually specified dimensions and tolerances for the screws, as well as the holes and countersinks in the rear trunnion. What I found was that the actual sizes of the screws, holes and countersinks were frequently outside of spec and some countries seemed to use slightly larger diameter screws.

After measuring and comparing screws and trunnions from Hungary, Poland, Romania and Russia, I set forth dimensions to try and fit as many as possible. One common element was that all trunnions seemed to use a 90 degree countersink so we moved ahead from there. By the way, this is why off-the-shelf American wood screws don’t fit very well – the typical US wood screw is made with an 82 degree angle vs. the correct 90 degree angle. In short, these look and fit right.

The head diameter is 8.8 +/- 0.2mm, the screw diameter is 5.5 +/0.1mm. Length is 25+/-0.5mm. As mentioned the countersink is 90 degree and the screwdriver slot is 1.9mm deep.

Lastly, the screws are a stainless alloy with an electrophoretic black finish for a rich consistent color. They aren’t going to rust on you. In the photos, you’ll notice the new screws are a shiny black due to the finish and the old ones are a worn dull black.
