Metal Hit Anchor Description

The Metal Hit Anchor is a precision die-cast, light-duty concrete anchor combining unusual toughness and remarkable strength. The Metal Hit anchor consists of a cylindrical zinc alloy body and zinc plated steel pin expander. The shank, from the bottom up, is split a major portion of its length. The anchor body has a bore, which runs through the head thickness and into the shank for a depth just beyond the point where the slot terminates in the body. The steel pin expander is made of high carbon steel, properly heat treated, and heavily zinc plated for maximum corrosion resistance.

Commonly Called

Metal hit anchors, zamac anchor, strike anchor, nail anchor, roof anchor, hammer drive anchor, thundernail, hammer drives, zamac hammer drive screw, zamacs, zamac nailin, hammer set, pin bolt.

• Nail comes in stainless steel.
• Dead loads only.
• Not recommended for overhead applications.

Metal Hit Anchor Approvals

Meets G.S.A. specifications FF-S-325, Group V, Type 2, Class 3.

Metal Hit Anchor Applications

Concrete, brick and block, light to medium duty.

Determine Metal Hit Anchor Length

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

Metal Hit Anchor Spacing Requirements

The forces on a Metal Hit 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. When vibration or sudden impact is part of the load condition anchor spacing should be increased.
