Split Drive Anchor Description

The split drive anchor is a one-piece tamper-resistant, pre-expanded anchor. The anchor is designed for use in solid base material such as concrete. They are available in high strength, heat-treated alloy steel, zinc plated in either a flat or round head style.

Commonly Called

Split anchor, split drive anchors, flat head split anchor, round head split anchor, split bolt anchor, sup-r-split, spike, drive anchor, CSD, countersunk split drive anchor.

Split Drive Anchor Features

• Diameter of anchor equals hole size
• Friction set
• Dead loads only

Approvals

Meets G.S.A. Specification FF-S-325, Group VI.

Applications

Light to medium duty in concrete.

Split Drive Anchor Length

Thickness of material to be fastened plus minimum embedment plus 1/4” equals anchor length.

Split Drive Anchor Spacing

The forces on a split drive anchor are transferred to the material that it is installed in. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchor. As a rule of thumb, the expansion industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. Where vibration or sudden impact is part of the load condition anchor spacing should be increased.
