    Tamperproof screw - what type is this?

    I have a WAECO RAPS36 COOLPOWER Battery pack that I want to repack, so I decided to investigate the internals to be sure that I purchased batts with terminals to suit and in so doing I fell at the first hurdle! when I encountered tamperproof screws securing the case halves together.

    It would not be a problem if they were TORX but theyíre ones Iíve not seen before. And to make things more difficult one screw head is damaged.

    I have a older (Blue Apple) version of a similar unit. From memory I managed to remove the screws using a big phillips head screw driver.

    The units just use std AGM UPS style batteries.

    I expected to need a phillips head driver but no.... Imagine a screw driver with the tip cut off and then 2 crosswise slots cut in the end so that it will mate to the raised cross in the screw head - thatís what I need and thatís the route I might have to take I canít buy the right socket tool.

    I replaced with the above
    The original wires are soldered to the terminals-I used the yellow insulated ring terminal and bolted the to the batteries.
    Regarding the screws to split the box, I'm fairly certain I used a long thin square blade screw driver.
    You will need to hold it against the screws with heaps of pressure- they are very tight!
    Good luck

    Thanks for the link Tamperproof screw - what type is this? Has been repacked once before by a Waeco service and repair agent and one of the screw heads is damaged so your suggestion may be the way to goTamperproof screw - what type is this?

    Would not a piece of Steel Tube with slots cut into it do the job? Even a piece of steel rod might do it, both with a Tommy Bar hole on the other end


    Whichever way you go it appears as though it will still require a fair old bit of inwards pressure to get a good grip as the head recesses look rather shallow.

    Oh yes, LH or RH thread? There could be a further trick waiting for you there.

    Good luck.

    Yup - and someone before has had trouble, or maybe it failed from over tightening. see photo....

    Iíd use a left handed drill bit and then an ezout. My other option would be to epoxy something like an Allen key (cheap and plentiful) in the head and wait for it to cure.

    edit: after another look, Iíd just get a flat blade screwdriver that fit as closely as possible and file a notch in the middle.
