Product Details
                            Brand new, genuine German HK production flat head screw for bayonet adapter.  This works with type-1 and type-2 bayonet adapters that use the odd-ball, HK specific threading that can't be found at a hardware store. 
   
   For those with Century imported HK33 parts kits, this is the correct screw for your bayonet adapter. 
   
   Later on HK used standard metric screws in type-3 adapters.  If you bought a surplus bayonet adapter from another vendor and it did not come with a screw; odds are this is the correct part for you.
