Product Description
The Simpson 1/4 in. x 1 in. Zinc Nailon Pin-Drive Anchor is a light-duty mechanical fastener from Simpson built for reliable performance under static loads in concrete, grouted CMU, hollow CMU, and brick. The simple pin-drive installation method - insert into a drilled hole and strike with a hammer - makes it a practical, time-saving choice for contractors and specifiers who need consistent holding power across a wide range of common masonry base materials.
Key Features
- Pin and head configuration make this anchor tamper resistant - once installed, the driven pin and mushroom head resist removal or manipulation without specialized tools, adding security to finished installations.
- Mushroom head design - provides a low-profile, flush seating against the work surface for a clean, finished appearance with no protruding hardware to interfere with adjacent materials.
- Zinc Nailon anchor body - engineered specifically for light-duty fastening under static loads, offering a reliable and cost-effective solution for everyday masonry anchoring tasks.
- Carbon-steel pin - delivers consistent driving strength, ensuring the anchor expands and locks securely within the base material upon installation.
- Die-cast Zamac 3 alloy anchor body - expands upon pin impact to grip the surrounding base material firmly, providing dependable holding performance in concrete and masonry applications.
Why This Product
- Trusted Simpson engineering at a practical price point - Simpson mechanical anchors are a go-to choice for contractors and specifiers who require proven, repeatable performance across demanding job site conditions without overspecifying for light-duty static-load work.
- Versatile base material compatibility - approved for use in concrete, grouted CMU, hollow CMU, and brick, this pin-drive anchor covers the most commonly encountered masonry substrates in commercial and residential construction.
- Tamper-resistant design adds long-term installation integrity - the pin and head configuration makes unauthorized removal significantly more difficult, making this anchor well suited for publicly accessible installations or secured fixture attachments.
- Fast, tool-minimal installation reduces labor time - the hammer-driven pin-drive method requires no setting tool or power equipment beyond a standard hammer and drill, streamlining the anchoring process on any job site.

Frequently Asked Questions
- How is the Simpson ZN25100 Zinc Nailon Pin-Drive Anchor installed?
- Installation is straightforward: insert the anchor into a properly drilled 1/4 in. hole in the base material, then strike the head with a hammer. This drives the carbon-steel pin through the anchor body, causing it to expand and lock securely against the surrounding base material.
- What base materials are compatible with this anchor?
- The ZN25100 is designed for use in concrete, grouted CMU, hollow CMU, and brick - a versatile range of common construction base materials.
- What makes this anchor tamper resistant?
- The pin and head configuration of the Zinc Nailon anchor is specifically designed to resist tampering. Once the pin is driven flush, the mushroom head and set pin make removal or manipulation without specialized tools extremely difficult.
- Is this anchor suitable for structural or overhead applications?
- The ZN25100 is rated for light-duty applications under static loads only. It is not intended for use in overhead applications or demanding structural applications requiring higher load ratings.
