Welcome to the Handy forum, Please drop down to the New Member topic at the bottom of the opening forum page and introduce yourself. You'll find a lot of answers to most of your DIY questions on this forum. After you've been here awhile you'll probably start helping others too.
If it turns out to be a 'blown fuse', what may have happened is that the battery was 'overheated' from heavy use when you put it in the charger. Next time, wait about 5-10 minutes and allow it to 'cool down' before placing the battery in the charger. My better quality Dewalt 'smart charger' won't let it start charging until that happens, but then it cost a lot more than the Handyman Toughtest tool set did. Maybe someone who owns one of the Toughtest Tool Sets can provide more info for you about this problem. If it happens again, I'd return the set to them.... but that might be a problem in itself.
Also, try browsing thru some of the older post on this topic and under the
Member Product Reviews
for more info about what other Handyman members think of the Toughtest tools.
The type of screw you have is probably a type of spanner
'security screw'. What you'll need is a special 'security bit set' that I've illustrated below. You can locate one at a Harbor Freight location near you or order one from the link I've posted below. Click on this link
for more info on them. Your local Lowe's or Home Depot might have them, but probably cost a lot more $. They are always useful to have in your toolbox since you never know when you might need them.
