Perkins 4.248 sump bolt. This part will fit all sumps drilled to take a parallel thread (the majority) sump drain bolt. Diameter across the imperial parallel threads is 19 mm (3/4 inch).
This bolt is not suitable for sumps drilled to take the less popular taper thread sump plug.
To finish the job off properly, we include a sealing copper washer with the sump bolt.
