Time after time I am unable to remove self tapping bolts. More often than not they break off. Two cases I refer to.... 1) Spindle Deck assemblies - Alum housings with steel self-tapping bolts. Most mandrels aka spindles have four bolts. There is always that one bolt that brakes, and in some cases two. 2) Mounting bolts on B&S engines - This is probably more important than the case above. heat/ice, solvents, penetrating oils, etc to no avail. When I put them back together, or when I'm installing new, I always put anti-seize on the new bolts before threading, this way whoever may end up with the lawnmower after me, will have better success - Pay If Forward. I've tried heating with propane torch -the kind plumbers use to solder pipes - followed by melting ice against the bolt head in hopes of freeing the bolt. I've tried all kinds of penetrating oils and solvents - those so-called - bolt breakers - with no luck what-so-ever. I've tried those reverse drill bits and ease-outs. The ease outs almost always break causing me to take two steps back. The reverse drill bits, although they drill a hole, they have never gotten the remnants of the bolt out. Who has a tried and true way of pretreating these kind of bolts without breaking them off? Getting them out after breaking them off? Is this just a pipe dream on my part? Wishful thinking? Or a fact of life?
