Setup, Compatibility & Care
To begin, ensure the pilot hole is drilled to the correct diameter recommended for the specific tap size being used. Use a T-handle or tap wrench to maintain a perfectly perpendicular angle to the workpiece, as angling the tap can lead to off-center threads.
Compatibility is strictly limited to BSP (British Standard Pipe) thread specifications; do not attempt to use these on tapered NPT (National Pipe Taper) threads as the profiles will not match. After use, clean all metal swarf from the grooves using a soft brush. Before placing the taps back into the provided red case, apply a light coat of machine oil to the threads to protect the alloy from moisture and prevent corrosion.
