These metal screws are ideal for joining sheet metal, metal to wood, or other soft or thin unthreaded material. They are made of steel with a zinc coating for corrosion resistance. The metal screws feature an oversized, slotted, hexagonal head with a washer that provides exceptional holding power across a wider surface area and makes them compatible for use with automotive cap screw wrenches. With their self-tapping thread and sharp point, the screws ensure smooth penetration into the material.
