  • Help on removing worn out allen key bolts?

    on my hockey blades the allen key bolts are worn and make almost a perfect circle. how can i remove these bolts? i wish they were the square one or the cross ones but these damn allen key ones are pissing me off.

    any help to remove it when its a circle? thanks in advance

    There are square screw extractors that sometimes can be tapped into those heads or you could just use the round hole as a drill guide and drill just deep enough to pop the head off and go from there.

      Impact the Allen head with a punch to shock loosen the thread then you could try hammering one of those star drive bits in; if that fails try the slow method with a cold chisel or centre punch.

      I hope this is of some help.

      cheers, Ken

      PS .Get a set of good quality Allen keys, use them correctly and junk the others.

        A spiral stud remover will work.

          You could also use a socket screw extractor. That is exactly what they are made for.

            I've had good luck hammering in a hardened Torx bit. this sets the bit and as suggested will shock the allen bolt.

              Any of the above should work. Adding a cheap impact driver into the mix will ensure success.

                Depending on how badly it is worn, a metric hex key can be tapped in and will not slip. As with any stuck bolt or screw, I always use release agent or thin oil on the screw first(AeroKroil works the best I find). You can also drill a small hole through the screw and spray oil through it so it can soak from the back side also. The small hole will sometimes release pressure on the screw and ease it's removal. Good luck.

                  You can take a #409 thin cutter disc on a Dremel tool and cut a slot across it and use a straight blade screwdriver on it.

                    Use one of the methods above, in combination with epoxy between head and removal tool. Let it set up and remove the bolt.

                      I have used vise grip pliers with good results.

                        If all else fails you can weld a nut on it and let cool, then spin it off.

                          I have a method I kind of learned from this board. i take a sharpened small chisel, and "burr" the old flats back into the hex area. Then I tap in the hex wrench and turn them out. Sometimes ou have to burr it in with the hex key already in, but it works. The original idea was to take a rounded center punch or line punch and tap the hex to burr it in, then put in the hex key.

                            What type of head and can you get to it? If you are dealing with counterbored hole and nothing else works try drilling from opposite side. If you cannot get in from that direction try left handed drill from the top. Drill will hpoefully hang and spin out screw. If not drill it out and retap. Drill straight !!!!!! Use cheap drills and buy more than one.
