The Simpson Zinc Nailon 3/16 in. x 7/8 in. Pin-Drive Anchor is a low-cost mechanical anchor engineered by Simpson for light-duty fastening under static loads into a variety of base materials, including concrete, grouted CMU, hollow CMU, and brick. The pin-drive installation method is simple and fast - drill a pilot hole, insert the anchor, then strike the mushroom head with a hammer to drive the carbon-steel pin through the anchor body, expanding it firmly in place. The unique pin and head configuration delivers a tamper-resistant hold, making this pin-drive anchor a dependable solution across demanding structural and construction fastening applications.

Key Features
