5-90, can you give a simple description of the annealing process for those of us tht are uninformed?
Annealing is a "softening" process for metal. For iron-based metals, it involves heating the metal through and allowing it to cool gradually.
You don't want to kill the heat-treatment entirely, but most people don't have access to that much heat (it takes something like 700-800*F to fully anneal steel.)
Home annealing is simple enough - put the parts in your oven, and heat to 400-450*F until they're heated through (it takes about 15 minutes to through heat straps in a fully-heated oven.)
Then, turn the oven off. Don't even open the door until the following day - allow a minimum of eight hours to cool.
Alternatively, pack the part in warm sand - and leave it in there for a couple of days.
This is why I keep several sets of straps on hand - having at least three simplifies things. One in service, one annealed set ready for use, and one being annealed (just in case. It's an extension of "Two is One, One is None.")
Screws? Don't bother annealing them - just buy a box of decent-quality socket head capscrews and pull a set of out of the box when you need them. Toss the old ones when you take them out. Don't forget the LocTite!
