MG MGB Technical - Source for Posidrive screwdrivers
I found a place to buy individual Posidrive drivers: SK Tools. Pretty reasonable. No, I don't get anything out of it. http://www.sktools.com/productcatalog.cfm?cfid=4020981&cftoken=72141634 |

Got a set for Christmas. My wife looked forever according to my daughters. Big surprise for me - bless her. She found them at Snap-on. |

It's not too hard to get pozi bits as part of those changeable multi-bit screwdriver sets. It's harder (at least in NZ) to get single pozidrive screwdrivers. It's impossible to get pozidrive impact driver bits (again, in NZ). I had to order mine online from the UK: They took several weeks (!) to process and arrive, but did eventually. http://medmaw.com/cgi-bin/medmaw/medmaw.cgi (no competing interests) |

Curtis Give Waitemata Hydralics a call (09)839-2040 They have at least 2 of everything ever made in the world. Ian F |

I believe you also get one when you buy the very cheap impact driver kit. And I think Sears used to carry them, but I guess it depends on the store. |
Jeff Schlemmer |

Rich (OH, USA) Sorry, can't answer your question. Most of the screws on my B's have been rounded out by someone with a philips head screwdriver. Know for sure that the door hinge screws are large pozi's. Yesterday was removing the door gasket on a GT trying to figure how the window trim was attached. You can guess - at least on the door side, all were little pozi's. You might drop an email to John Twist (JohnTwist@UniversityMotorsLtd.Com) or Carl Heideman (carlheideman@yahoo.com) - they're far more knowledgeable. P.S. I didn't know how much they cost, but I wish I had had this pozi set for the last thirty plus years. My wife got me a handled set (#SDDZ50A). A bit set might be better - cost wise. |
Steve Buchina |
Well, I'll be - it seems as though Repco are now stocking Pozi #2 screwdrivers as part of the 'Professional' range. Those multi-bit sets are also a way to get hold of pozi bits. Ian: I called Waitemata Hydraulics early in my search for impact driver Pozi bits - but they don't carry them as regular stock, and would have had to order 'em from overseas. Steve: The large door Pozi's are best serviced with a number 3, and I've found a number 4 pozi actually best fits the (when new) large screws holding the rear GT hatch on. |
Curtis Walker |
(addendum to above post) BTW< those are number 3 and 4 impact driver bits, which are larger than their regular bit counterparts. |

Curtis, Just wondering how tight one needs to get on those door hinge pozi's? Would hand tight be sufficient? Think it was in the early 70's that I first tackled door removal on a MGB. Didn't have a pozi. First tried a large handled philips. Screws wouldn't budge. I didn't have air tools back then. Had to use one of those hand held impact drivers - you know, where a hammer in the other hand provides the impact. I destroyed those screws, but they came out. Got some better looking screws at my local B-junkyard (they had air tools) and rehung the door using my large philips (hand tight). Door seemed to hold quite well - hinges held tight. Wonder if hand tight would work as well on GT hatch hinges? There's more closing stress on the hatch door (spring loaded). Larry, Thanks for the Sears info. I'm guessing that I'll need a #3 and #4 to get the old pozi's out (air impact). Will be replacing with new ones (hand tight?). |

Interesting thread. Do I read that Pozidrive screws and drivers are becoming a thing of the past as they still seem common in UK. In fact joiners are more and more using poz head screws so if anything they are becoming more common. Now. door hinges must be slackened off using an impact driver with poz bit but tightened by hand. Re the tailgate this doesn't seem to present the same problem but if it is tight then use the impact driver rather than risk damaging the head as a hand held driver rises out and bruises it. |

Ian It appears that Pozidriv is becoming more common in the area of wood (deck) screws but I can't find a source for machine screws. Anyone know a source of Pozidriv machine screws to use a replacements for those used in our cars? Anyone know of a source of #4 Pozidriv bits? Thanks Larry |
Larry Hallanger |
Larry, I know it's a UK source but I get everything I cant get locally from these people. http://www.namrick.co.uk/ Have a look, its a good resource. |

Steve, I just took my 71 GT's hatch off recently to replace the upper rubber seal. Sod of a job to remove the screws, which, because of time and the torque of the hinge joint, had become immoveable, even with an impact driver. Eventually I had to get the panel shop to drill 'em out. To prevent a future similar occurance, I've now secured the rear hatch with 7/16 x 1 inch bolts which can be tightened/loosened with an ordinary wrench or socket. A MUCH more robust solution than the OE silly large screws (if a little less elegant). |
Curtis Walker |
Ian Good source, but I do not find anything on Pozidriv screws. Am I missing something? Thanks Larry |
Larry Hallanger |
Larry, I don't think you are missing anything however their catalogue certainly details all these products. I assume that in general the poz screws that you are looking for are the many that are used to hold on body fittings clips etc which form memory are No10x32tpi and they cartainly have these. Can I suggest you request a catalogue and take it from there as they have supplied anything that I every needed for two full mgb restorations. |
Iain MacKintosh |
Ian Will follow up with a catalog request. And yes, the 10-32 AND the others that are used such as the flat head screws that hold the door hinges to the body and door. Thanks Larry 69 C in restoration |
