If you are using our risers and your rings are 1/4-20 these 3" long screws will allow you to use those our risers with a Losmandy style rail or plate. Make sure you measure the length of your existing screw and depth of thread on the mounting rings to see if a 3" long screw will work. Generally these work for Losmandy sized rails but that depends on how the rails are made. Price includes 4 screws.
