Although I'm an engineer in aerospace, I don't own and don't use a torque wrench for anything I do at home on personal things. I know it's wrong, but that's how I grew up, and it's always worked for me that way. Don't worry, I do enforce the torques at work, so you can safely assume the evacuation slides from my company will work, if maintained properly.

 

Inch pound torque wrench is worth it
and like resharp said, half inch 50 / 250 foot pound is worth having and 15 to 19 foot pounds is just a good pull on the wrench, craftsman from Sears used to be good for home use, but I haven’t bought any craftsman in years, not sure of their quality now, inch pound a bow type is good, on the higher side the click type is easy to use without having to look that close
