Drive standard 5/16" (also 8mm) hex washer head screws including #10 and #12 self-drilling tek screws and Tapcon style screws with total confidence using the AutoLock™ driver. This driver locks onto a screw to eliminate dropping and bucking screws sideways for greater productivity. Unlike magnetic screwdriver bits that attract metal shavings, this driver stays free of debris. 

Operation:

1. Hold a screw near the tip and push it into the driver. The driver triggers forward to lock in the screw.
2. Drive the screw all the way in. The head is automatically released shortly before full install.
3. Repeat

Features:

• Patented design easily locks onto screws when loading and self releases during installation.
• Heat treated alloy steel for long life.
• 1/4" hex quick change shank.
• Floating neo-bonded washers will not interfere with tool operation as long as there is a 1/4" gap between the washer and screw head.
• Largest diameter of tool is 1"
• 1/2" minimum recommended screw length.
• Since AutoLock™ drivers lock around the screw head, non-standard screws with washer head diameters greater than 7/16" are not compatible with this driver.  Looking to drive a different type of screw? Send us a message through our About Us page.
