Product Details

The Taper BoltĀ® concrete anchor is a two-component, expansion-type unit offering high strength and a finished head style. It consists of a Grade 5 bolt with special threads on a tapered end, and a matching-thread, two-part expander nut. When inserted into a drilled hole, the expander nut bears against the sides of the hole and, as the anchor is turned, the nut expands parallel to the sides of the hole. It delivers uniform expansion for greater strength and holding power. The anchor is removable and can be reused multiple times.
