## Description

The steel self-drilling screw with zinc plating has a wafer head and a star drive. Steel is often used in applications where strength is the primary consideration. The zinc plating offers corrosion resistance and has a reflective appearance. The wafer head has a flat top, a 70-degree cone-shaped bearing surface, and a small slope between the top and the bearing surface that helps create a flush fit. The star drive, also called a Torx drive, has a six-pointed indentation that provides a large contact area for the driver, resisting slippage better than a Phillips or slotted drive. A star drive requires use of a Torx driver for installation and removal.Self-drilling screws, a type of self-tapping screw, are threaded fasteners that drill their own hole and thread it as they are installed. Usually only recommended for use with metal, self-drilling screws are available with wings that enable use when fastening wood to metal. The drill point length should be long enough to penetrate both materials being fastened before the threading portion reaches the material.

### ⭐⭐⭐⭐⭐ Great Product! Fast Shipping! Recommend Seller!

Great Product! Fast Shipping! Recommend Seller!

### ⭐⭐⭐⭐⭐ Strong screw
*by R***N on July 9, 2022*

When I was looking for a self tapping screws.The seller sites all said for wood, not intended for metal. They looked like any other self tapping screws I’ve used. I removed a section of floor from a boat. It was originally install with blind rivets. I decided to used screw to reinstall the floor for future access. These screws had the flat head I needed. If they won’t drill metal I can drill pilot holes. When I receive the screws they looked like they would drill metal. I used a 3/16” piece of steel. I used a lower speed because my thinking was when the threads reached the metal the screw might snap. As the picture shows it work just fine. I’m mounting wood to aluminum. Notice, I had the 3/16” steel mounted in a vice for safety.

### ⭐⭐⭐⭐ Use Quality Torx Bits!!
*by C***B on May 16, 2025*

I will say this much…do not use cheap torx bits.The torx indentation is somewhat shallow…plus being the material these screws are made from..cheap bits will not grab the screws well plus cheapo bits will strip out fast.After buying quality torxs bit these screws performed far better though you’ll still need to put pressure straight forward on the screw heads.The drill edges work..but not 100% reliable.Yes..I’d buy these again because of quantity…I needed a lot of these screws. And performance is acceptable when using quality torx bits as noted.
