Extension M5 20 mm long

Extension M5 20 mm for trailer

Extension with an M5 thread, listed at a length of 20 mm and a total length of 26 mm. It is the smallest in the range; the others are M6 at 25 mm with a 30 mm total length, and M8 and M10 at 25 mm with a 35 mm total length.

The thread decides the fit

An extension only works if its thread matches the part it goes into — an M5 will sit loose in an M6 seat, and forcing the wrong size ruins both parts. Read the thread off the part you already have rather than judging it by eye, and note that two figures are given here: 20 mm as the length and 26 mm as the total length.
