Wider than other rounded heads, the truss head spreads pressure over a large area without adding a washer. This reduces the risk of crushing thin material, such as sheet metal. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.
Length is measured from under the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
