Square drive screws offer a great option when you need a strong connection between driver and screw that resists "cam-out" and slippage. The deep square socket and the 90° angles of the corners provide powerful torque and power for driving into solid materials.

Fastener SuperStore offers Square Drive Screws in the following screw categories:

• Deck Screws

• Drywall Screws

• Machine Screws

• Self-Drilling Screws

• Self-Tapping / Sheet Metal Screws

• Thread Cutting Screws (Types 25 & F)

• Wood Screws

Screws using this style of drive will require a specific driver size, dictated by the size of the screws. The spec sheets linked on our part pages will provide you with information regarding which driver size you will need. These are referenced in the driver size column, most commonly noted as 0; 1; 2; 3 or 4.

Most are offered in combination with a wide variety of head styles, and in multiple material / finish combinations. If you know that using a Square Drive is the right solution for your application, we've created a central page for accessing all of the options we offer. Check out our full selection here!

We also carry the drivers / bits used to drive these screws. Insert Bits for hand tools are located here; while power bits for power drivers are located here!
