About Socket Head Screws

Fully Threaded

Aluminum screws are one-third the weight of steel and have good corrosion resistance. Length is measured from under the head.

Screws with a blue-anodized finish are easy to distinguish.

Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch.

Aluminum Hex Head Drilling Screws for Aluminum

One-third the weight of steel, aluminum screws resist corrosion in wet environments and are nonmagnetic. Use them to fasten aluminum to aluminum. The hex head allows for a secure grip with a wrench and a flange reduces the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the flange. Head height includes the flange.
