Classic Mini 1/4 UNF X 1/2 Inch Bolt

Until the Verto/injection type cars, most Minis had a small inspection hole for checking timing at the top of the clutch housing. These 1/4"unf bolts 1/2" long hold on that plate but you can use shorter type SH604031 also.

Also used for some metal fans to water pump.

For plastic fan and later water pump Pulley to water pump use GFK5179 1/4""unf 3/4"long.
