- Using 'wing bolt' for any bolt with an unusual head.

Pliers or an adjustable wrench can be used on the wings. In some designs, a slot for a flat-head screwdriver is also present in the head.
Commonly steel (often plated), stainless steel, brass, or nylon/plastic for lightweight or corrosion-resistant applications.
