Hammer Drive Pin Anchors in Zinc Plated Steel
Hammer drive anchors can be used in concrete, block, brick and stone. The single head nail like expander pin provides a permanent, tamper proof installation.
The body is made of zamac alloy and the nail is made of carbon steel. These anchors are suitable for light duty applications including roof flashing, brick ties, electrical fixtures, furring strips, light duty mechanical attachments and maintenance but should not be used in overhead or sustained tensile loading applications.
Installation
- Drill a hole in base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to specified embedment depth, plus ¼" for pin extension, and blow hole clean using compressed air. Alternatively, drill the hole deep enough to accommodate embedment depth and dust from drilling.
- Position fixture and insert Nailon anchor.
- Tap with hammer until flush with fixture, then drive pin until flush with top of head.
- All metal light duty impact setting.
- Tamper resistant once fully set.
- Comes in 22mm, 30mm, 50mm in zinc plated or stainless steel.
- Easy hammer in method of installation.

Hammer drive anchors are made of a metal pin with an expansion sleeve that is driven into a pre-drilled hole using a hammer. As the pin is hammered in, the sleeve expands and grips the material, to provide a secure hold. Hammer drive anchors are typically used for attaching electrical boxes, signs, and other light to medium-weight fixtures to masonry or concrete surfaces.
