Important Product Questions
Which exact accessories are included?
The kit has 5/32 and 3/16 in concrete-screw drill bits, each 6 in overall; 1/4 and 5/16 in nut drivers; 2 in T25 and T30 TORX power bits; and a drive sleeve.
Which bit matches each concrete screw?
Use the 5/32 in bit for 3/16 in concrete screws and the 3/16 in bit for 1/4 in concrete screws, subject to the screw maker’s installation instructions.
Does the sleeve replace the anchor instructions?
No. Confirm the required hole depth and cleaning procedure, then follow the specified drive setting. A collar or recessed driver does not guarantee a correct installation.
