Threaded Flute Plug for Machine Shops
The Westward 440-2272 H5 flute plug is a machine-shop component cut to a 1/2-13UNC thread with an H5 thread limit. It suits maintenance teams and machinists who need a reliable plug for standard coarse-thread ports in fixtures or fluid systems.
Verify Thread Compatibility Before Ordering
Confirm that the receiving port uses a 1/2-13UNC thread form and that an H5 limit matches your fit requirement. The plug is designed for this specific coarse-pitch series; mismatched threads or a different limit class will prevent proper engagement or sealing.

Questions about this item
What thread size and limit does the Westward 440-2272 H5 plug have?
The plug is cut to a 1/2-13 UNC thread with an H5 thread limit, matching standard coarse-pitch taps for that diameter.
Which thread limit should I select for a general-purpose 1/2-13 UNC hole?
Choose the H5 limit when you need a standard class-of-fit for typical steel or aluminium work; it provides the conventional tolerance band for this thread size.
How does the H5 limit affect the fit when the plug is installed in a machine?
H5 places the pitch diameter near the middle of the 2B/3B tolerance zone, giving a reliable interference fit without excessive torque during assembly.
