Simpson Strong Tie ZN25112 1/4" X 1-1/2" Mushroom Head Zinc Nailon™ Pin Drive Anchor

Zinc Nailon anchors are for applications under static loads, easily installed by hitting a hammer on the head that drives the pin through the anchor, expanding the body of the anchor to hold it in place. The perfect choice for concrete, CMU, brick, and other base materials. Pin and head configuration is designed to make anchor tamper-resistant. This product is not for use in overhead 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 1/4" 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.
