If you haven’t seen a set of these before, we’re not surprised; Offset wrenches aren’t a common find. They’ve been around for a long time, but you can go a long time in the shop without having a burning need for one.
But when you do finally come across that need it will indeed burn, and the virtues of the offset wrench can make your project go from nightmare to possible — as we found out recently trying to remove a water pump from an ’89 Porsche 944S2.
Offset wrenches are just normal normal box-end wrenches with a bend on each end that helps them reach deeply countersunk nuts or bolts that you can’t get at with sockets or standard wrenches.
The kit shown here offers two sizes on each wrench and they’re available in standard or metric sizes. It’s from S•K Hand Tools, and it’s available at a street price of around $110. Not cheap, but if you need them you need them pretty bad.
PS: Time to ‘fess up. The set we used was borrowed from a friend, and was significantly cooler than this set. It featured an almost 90-degree offset, which was absolutely perfect for fitting into the deep pulley we were dealing with. A lesser offset wouldn’t have handled the job. We’re still looking for the details on the set we used, and when we find it we’ll pass it on — right as soon as we order one for ourselves.
