Ignition wrenches are one of those tools you’ll never need until that one moment when Murphy’s messing with you, and then nothing else will do. Normal wrenches have a 30-degree offset in the head to allow for rotating hex bolts by thirty degrees at a time, but that’s too much for some very tight situations. That’s where ignition wrenches come in. With a 15-degree offset on one side and an 80-degree offset on the other, you only need five degrees of rotation to spin a bolt. Tedious, yes, but sometimes those small increments are all you can manage.
Pricing is reasonable from Craftsman, at $20 for a set of eight metric wrenches, and the same price for eight inch wrenches. Snap-On, naturally, has similar options at the stratospheric price of $224. Personally, I’ll take 91% off and go for the Craftsman set.
