Question 6

What are self-piercing screws

Accepted Answer

Self-piercing screws are manufactured to pierce light gauge metals, tapping their own mating threads as they are driven into the surface material. While similar to self-tapping screws, self-piercing screws feature an extra-sharp point allowing for penetration into certain metals. Also known as zip, needlepoint, saber point, sprint point, and twinfast screws, self-piercing screws are efficient fasteners when used with compatible metal materials.

Question 7

What are socket cap screws

Also known as Allen head screws, socket cap screws feature an internal hex socket drive in the head of the screw. Because the drive of the screw is internal, these screws have a smaller surface area than hex cap screws, making them ideal for applications requiring a smaller profile.

Question 8
