Greetings All. Put the doors back on the project today (yahoo!) '63 Cooper. There are two c/sunk screws that hold the nylon wedge to the door. Found those srews. However, there are also two (bit shorter) that hold the steel cup that the nylon wedged slides into (on the "B" pillar) I went to the local hardware, thinking they may be UNF. He rattled off some other thread name. Does anyone know what thread these c/sunk screws are? Thanks Alex. |

Are these screws about 0.125" in diameter? 5-40 UNF is the thread for this diameter. Take a look at the thread listing here: http://mdmetric.com/tech/thddat9.htm |

You need to go to a real nut & bolt shop (ie. a fastener specialist), not Bunnings etc. |

In a bind, the hobby shops specializing in actual hobbies, not toys, sell a lot of these small screws and taps. usually found in the accessory screw packs. |

Yeah, sorry for the bum steer. The threads used around the car for metal thread screws are usually the 5-44. The door nylon mounts use the 6-32 however. I pulled a screw from the door and got the same thread count. I counted 20 threads over 5/8 length so (8/5)x20=32 TPI It might be the thin adjustable metal strap which requires the coarse thread. |

According to the Mini Series parts book PUB1056M following are the part numbers for the various screws on the door and B pillar for a Mini Cooper (and Morris 850): CMZ308 - for the zinc diecast striker plate CMZ212 - for the nylon buffer and retaining plate CMZ204 - for the buffer plate (u-shaped steel to house nylon buffer) According to the BMC Standards book: CMZ means it's a zinc plated recessed countersunk-head screw - unified 204 is No. 6 and 1/4" long 212 is No. 6 and 3/4" long 308 is No. 10 and 1/2" long No. 6 is UNC, 32 tpi, .138 nominal diameter No. 10 is UNF, 32 tpi, .190" nominal diameter |

Winabbey. Spot on. 6-32 UNC for the nylon and metal cup guide it goes into. They're only about 12c ea, but they come boxed in 100. And the B Pillar latch are bigger screws. Cheers Alex. |
