I am not on the paylist of Loctite , just using the name for clarifying the kind of sealant. There are lots of other companies with similar products - at better prices possibly - just that I am familiar with some Loctite types, the 221 or 222 are low strength thread lockers. Mostly I use low to normal in most places, rarely a need for higher strength which can be a handful when trying to undo. Just it amazes me a bit that these products are less accepted in classic mechanics , instead people revert to silly safety wires, nylocs, split washers and more like these "safety" items which are often not really safe. And no, no Allen bolt in that place, ugly.
