HFRR Gasoline Screw Set

The gasoline screw set is made up of a selection of screws used on the HFRR system, primarily for the gasoline conversion kit.

The two longer black cap head screws are to secure the lower specimen holder, and the shorter cap head screw is to secure the upper specimen holder. The two stainless steel button head screws and two grub screws are the same as the standard screw set selection. The two stainless steel button head screws are to secure the lower specimen (disc) inside the holder, while the grub screw is to secure the upper specimen (ball).
