Titen Turbo 1/4 in. x 2-1/4 in. Flat-Head Concrete Screw
Titen Turbo is Simpson's concrete and masonry screw anchor. This is the 1/4 in. x 2-1/4 in. flat-head version with a T30 6-lobe drive, which sits flush in a countersunk fixture. Drill a 3/16 in. hole and drive it in; no plug or anchor sleeve needed.
Zinc plated with a ceramic coating for dry, interior use. It is not rated for exterior or wet exposure.
Features and Common Uses

- Installs with a standard ANSI 3/16 in. bit
- 100 per box
Commonly used for:
- Electrical boxes, conduit and light fixtures
- Furring strips and thresholds on basement slabs
- Shelving and handrails on concrete or block
