Most all POZISQUARE screws can be driven with a standard #2 square driver bit. However to have the added benefits of ACR, we recommend the POZISQUARE Driver Bit. Most packages come with both bits!*

The Difference between Square and POZISQUARE

A standard square drive has four points of contact (each corner). When driving straight on all four corners connect and the screw drives in well. With POZISQUARE the square is still utilized and a Phillips portion is added for additional points of contact. This means if one of the corners strip out, there are still additional points of contact.

POZISQUARE has patented ACR

ACR stands for Anti Camout Recess. Camout means stripping while driving the screw in. POZISQUARE screws have a padded ledge in the recess of the screw. The ribs on the driver bit match up with the ledge. This allows for more torque, won’t strip out and can be driven off angle.

Driving off angle

Many times when installing screws, the driver bit can not be straight on to the screw. (Think of installing a screw next to the wall of a house). POZISQUARE screws can be driven off angle with a POZISQUARE bit. It allows for more torque.

POZISQUARE bits come in a 1 inch or 2 inch length. See stores for 2pk or 5pks of bits. Note 1/16 the 1/4 inch concrete screws require a #3 POZISQUARE driver bit.

*see packages for details. POZISQUARE concrete screws, Carriage Bolts and Lag Bolts do not come with driver bits unless indicated on the packaging.
