Jaw Set, For Use With Kliker II No. 5X719 and HP-2(R) Deluxe No. 4X577, Part Type Jaw Set, Material Steel. & Recepticles. Electrical Outlets. Light Industrial. and Enclosures. Electrical Boxes. General Purpose.
I have had to replace the jaws three times in my Marson HP-23A riveter. This isn't really the tools fault. I seem to break these when using the larger size rivets with steel mandrels. In other words they are tough to snap. As a result it will sometimes break at least one of the jaws. These are good jaws but they aren't great jaws. Unfortunately you don't have any other choice. Or at least I couldn't find anything different. But they work great as long as you don't over do it with them. I do recommend them mainly because they are all you can get. I now own a large riveter to handle the larger rivets and I will keep this one for the smaller size and aluminum mandrels. Hope this helps!!
