The shank length is not always the same at the thread length, which is the case if the insert has a threadless portion (sub-shank) Tenon designates the thread length; Shoulder designates the barrel diameter in front of the thread portion; Unless otherwise mentioned, right hand threads are assumed. Left hand threads are designated "LH".
Driving bands and obturator rings are made from material that will deform and seal the barrel as the projectile is forced from the chamber into the barrel. Sabots use driving bands and obturators, because the same manufacturing tolerance issues exist when sealing the saboted projectile in the barrel, but the sabot itself is a more substantial ...
The hook's design allows traction forces to be relayed through the curved/indented portion to and from the proximal end of the hook, which is either a straight shaft (known as the hook's shank) or a ring (sometimes called the hook's "eye") for attachment to a thread, rope or chain, providing a reversible attachment between two objects.

A tee is an object (wooden or plastic) that is pushed into or placed on the ground to rest a ball on top of for an easier shot; however, this is only allowed for the first stroke (tee shot or drive) of each hole. Conventional golf tees are basically spikes with a small cup on the head to hold the ball, and are usually made of wood or plastic ...
A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, [1] copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell and engages the barrel's ...
