The Val-Pak AquaFlo A and Dominator shaft extension screw is designed for compatible applications requiring a 1/4-20 by 5/16 inch fastener to secure the extension hardware correctly. Specialty screws like this are useful because the integrity of the surrounding assembly often depends on using the right thread, length, and fit rather than a generic substitute.

This replacement is especially useful when the original screw is stripped, corroded, lost, or no longer trustworthy during service. In shaft extension applications, the correct fastener helps protect alignment, retention, and the overall quality of the rebuild.

The V40-401 is a smart repair detail when accuracy matters and the goal is to finish the job with the hardware the assembly actually calls for.
