Unfortunatley, many of the Bipods and mounts manufactured don't seem to include the mounting hardware. These 10-32 thread 3/8" screws fit most Bipods that accept the 17S style footprint and mounts. You may need to measure the depth of the screw you need since there are some dimensional differences from brand to brand but this length should fit most commonly availble mounts and Bipods. These feature a Hex drive style and are Black-Oxide Alloy Steel for longevity and some corrosion resistance. 2 screws per pack.
