Taking a page from BlueBomber, who started one of my favorite threads on double box-end wrenches, I'd like to start a thread on "tappet" wrenches.
Wikipedia defines a tappet wrench as:
I've been a gear-head my whole life, and originally discovered the need for a thinner wrench at the age of 10 when trying to tighten the hub of a bicycle wheel while it was still mounted to the bike. I bought my first set of Craftsman tappet wrenches back in the late 80s. Now I buy any used tappet I see.

Wikipedia defines a tappet wrench as:
A spanner of small to moderate size constructed similarly to an open ended wrench, but with a thinner cross section. Its purpose is to apply torque to the fasteners found on the valve trains of older engines, especially automobile engines, where the valve train required adjustment of the tappets (also known as lifters). Tappets, push rods, rocker arms and similar adjustable pieces are often equipped with locknuts which are thinner than standard nuts, due to space limitations. Frequently, the hex section of the adjustment is contiguous to the lock nut, thus requiring a thinner "tappet wrench" to be used.
