Confast Sammys Anchor
Concrete Fastening Systems LLC

Confast's Sammys Anchors are designed for anchoring into concrete using Sammys nut driver. This anchor saves time from traditional methods and reduces installation costs.


  • DRIVE: Sammys #14 (Black) Nut Driver (8113910) 
  • ROD SIZE: 3/8 in.-16 
  • MOUNT STYLE: Vertical 
  • SUBSTRATE FASTENER SIZE: 5/16 in. x 1 3/4 in.
  • LENGTH: 1.75 in.
  • DIAMETER: 0.3125 in. 

Note: DO use a 1200 maximum RPM drill for installation. Do NOT install concrete screws while the drill unit is in impact mode — doing so will destroy the pullout factor of the fastener.

Special Nut Driver System

The nut drivers were designed with a unique spin-off feature that provides a fast and safe installation each time. When the face of the driver comes into contact with the material you are installing into, continue drilling until the nut driver spins free. Installation is then complete. Warranty requires the use of the appropriate nut driver for installations.

Installation Steps:

  1. Using an SDS 250 carbide tip bit or a HEX RECEIVER with a #250 carbide tip bit, pre-drill the concrete member to a depth of 2” with a hammer/ rotary hammer drill set on impact mode.
  2. After pre-drilling has been completed, install the SLEEVE TOOL over the bit (the bit should remain in the drill), and insert the #14SW (red) nut driver (p/n 8114910) into the opposite end.
  3. Insert the SWC screw into the nut driver.
  4. Place the tip of the screw into the pre-drilled hole, turn the impact/drill unit to drill mode and begin insertion. When the nut driver spins free on the SWC screw, installation is complete. Stop and remove drill.
  5. The SWC screw is ready to receive 1/4 in., 3/8 in. or metric all thread rod or bolt stock.
