The Simpson 1/4 in. x 2 in. Zinc Nailon Pin-Drive Anchor from Simpson is a low-cost mechanical anchor engineered for light-duty fastening under static loads. Trusted by specifiers and contractors alike, it installs quickly and securely into concrete, grouted CMU, hollow CMU, and brick, making it a practical go-to for everyday anchoring tasks where reliable performance and simple installation matter most.

Key Features

• Pin and head configuration make this anchor tamper resistant - once the pin is driven, the anchor cannot be easily reversed or removed, adding a layer of security to finished installations.
• Mushroom head design - provides a low-profile, broad-bearing surface that seats flush and evenly against the material for a clean, stable finish.
• Pin-drive installation - insert into a pre-drilled 1/4 in. hole and strike with a hammer to expand and lock the anchor body in place, reducing installation time and requiring no specialty tools.
• Zinc Nailon anchor body with carbon-steel pin - the combination of die-cast Zamac 3 alloy and carbon steel delivers durable, dependable holding strength for light-duty static load applications.
• Compatible with multiple base materials - approved for use in concrete, grouted CMU, hollow CMU, and brick, giving installers flexibility across a wide range of common construction substrates.
