Tamper-Resistant Pin-Drive Anchors for Block and Brick

A tamper-resistant nut prevents unwanted removal of the object you are anchoring. Turn the nut round side up for a domed look or countersink the nut flat side up for a flush surface. To install, hammer the pin to expand the end. When the pin is flush, the anchor is set. Pull-out strength and shear strength values are 25% of the ultimate values.
