The Split Drive anchor is a one piece anchor, with a split-type expansion mechanism on the working end. As the anchor is driven into the hole, the expansion mechanism compresses and exerts force against the walls of the hole. Can be installed in concrete, grout-filled block and stone. Available in mushroom, countersunk and duplex-head styles. The duplex head Split Drive is designed for temporary fastening applications and can be removed using a claw hammer.
Warning for CSD and MSD only: Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Accordingly, use these products in dry, interior and non-corrosive environments only.

MSD/CSD/DSD Product Data
- Mechanical galvanizing meets ASTM B695, Class 55, Type 1. Intended for some pressure-treated wood sill plate applications. Not for use in other corrosive or outdoor environments. See corrosion information for details.
Caution: Oversized holes in the base material will reduce the anchor's load capacity. For CSD and MSD, embedment depths greater than 1½" may cause bending during installation.
- Drill a hole in the base material using a 1/4" diameter carbide tipped drill. Drill the hole to the specified embedment depth and blow it clean using compressed air. Alternatively, drill the hole deep enough to accommodate embedment depth and dust from drilling. Overhead installations need not be blown clean.
- Position fixture and insert Split Drive anchor through fixture hole. For CSD and MSD, 3/8" diameter fixture hole is recommended for hard fixtures such as steel. For DSD, 5/16" diameter fixture hole is recommended.
- Drive anchor until head is flush against fixture.
