    52 TD how to replace fender captive nuts

    Subject: 1952 MGTD_Looking for captive nuts for the back fenders

    I am restoring a '52 MG-TD. I am looking for a source for the captive nuts for the back fenders. Some are still on the inner fender, I think they are 5/16 British Fine. I will also need some other sizes as the project progresses.

    I would also like to find a handle for my original jack.

    Can you help me?

    Thank you,



    Thank you for your inquiry.

    The captive (or caged) nuts are not available as such. The "cages" on the fenders are part of the bodywork and the nuts inside them were placed there before the "cages" were closed when the fenders were manufactured. If your "cages" cannot be re-used by putting new nuts inside them and then pinching them closed, what I have done in the past to provide a nut for the fender-securing bolts is to epoxy the nuts in place on the inner fender. JB Weld works very well for this purpose and the only trick is to put a bolt and washer through the nut from the underneath while the epoxy is drying. This does two things: it makes sure the nut is tight to the inner fender and also aligned correctly so the bolt will start easily when you are assembling the fender to the car.

    Moss Motors sells 5/16" BSF nuts under the part number 311-140. Moss has quite a complete range of British nuts and bolts available; you'll find them in the MG T-series catalog (or on line at listed under Hardware.

    We did some research on the web and found a pictorial guide that explains in some detail how to make replacement captive or caged nuts.

    It is quite a process, involving the services of a friendly machine shop.

    I regret that we do not know of a source for used original jack handles. Consider posting an "item wanted" email on one of the MGT forums.

    If you wish to spot-weld new caged nut to the inner fenders, captive square nuts and the correct retainers are available in two sizes (10-32 and ¼-28 screw size) from Todd Clarke at Clarke Spares.  I used the ¼-28 on my TF.

    Another source for a suitable replacement if you need larger sizes such as 5/16" is McMaster-Carr. They call them "easy align weld nuts"
