The Simpson 1/4 in. x 1-1/4 in. Zinc Nailon Pin-Drive Anchor from Simpson Strong-Tie is a low-cost mechanical anchor engineered for light-duty fastening under static loads. Designed for easy, secure installation into a variety of base materials - including concrete, grouted CMU, hollow CMU, and brick - it delivers dependable holding power across a broad range of common construction applications. The pin-drive mechanism allows fast hammer installation, making it a practical and efficient choice for contractors and specifiers who need reliable performance on the job.

Key Features

• Pin-drive installation - simply strike the head with a hammer after insertion, allowing fast, tool-minimal installation that keeps projects moving efficiently
• Mushroom head design - provides a low-profile, flush finish that sits cleanly against the surface for a neat, professional result
• Tamper-resistant pin and head configuration - once driven, the anchor resists removal or tampering, adding a layer of security in accessible or public-facing installations
• Die-cast Zamac 3 alloy body with carbon-steel pin - the combination of materials supports reliable expansion and consistent holding performance in light-duty static load applications
• Compatible with concrete, grouted CMU, hollow CMU, and brick - broad base material compatibility reduces the need to stock multiple anchor types for common masonry and concrete work

Frequently Asked Questions

How is the Simpson ZN25114 Zinc Nailon Pin-Drive Anchor installed?

Installation is straightforward: after drilling a 1/4 in. hole in the base material, insert the anchor and strike the head with a hammer. This drives the carbon-steel pin through the anchor body, expanding it outward to grip the base material securely and lock the anchor in place.

What base materials is this anchor compatible with?

The ZN25114 is designed for use in concrete, grouted CMU, hollow CMU, and brick. These are the base materials specified by Simpson Strong-Tie for this anchor.

Is the ZN25114 suitable for overhead or dynamic load applications?

No. This anchor is intended for light-duty applications under static loads only. It is not designed for use in overhead applications or where dynamic or vibratory loads are present.

What makes this anchor tamper resistant?

The pin and head configuration of the Zinc Nailon anchor is specifically designed to resist tampering. Once the carbon-steel pin is driven and the anchor body expands, the mushroom head and pin geometry make unauthorized removal difficult without specialized tools.
