Concrete Screw Large Diameter Zinc

These high strength large diameter concrete screws are designed for both cracked and un-cracked concrete. Oversized hardened threads cuts its own threads into concrete.  Code approved and easy installation; save time and money without sacrificing performance.  These anchors provide superior performance to wedge style mechanical concrete anchors and install in half the time. Finish is Zinc plated.

Installation

Drill a hole in the base material using a carbide drill bit the same diameter as the anchor you are using. Drill the hole to the specified embedment depth plus minimum hole depth overall to allow the thread tapping dust to settle. Before inserting the anchor into the hole blow it clean using compressed air.  Tighten the anchor into the base material until the hex-washer head contacts the fixture.

• If installing into hollow CMU do not use impact wrench
• Oversized hole will compromise the anchors performance
• Can be removed and reinstalled – ideal for temporary anchoring applications and those requiring service
