Questions & Answers


Can the nailon pin drive anchor be used in ungrouted hollow masonry walls?

Asked by JEAK January 20, 2020

The Zinc Nailon Pin Drive Anchors are only tested/rated for tension and shear loads in normal-weight concrete. Thank you!

How deep to drill into brick? Can you remove these from brick ?

Asked by Ed August 21, 2017

1. 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. 2. Position fixture and insert Nailon anchor. 3. Tap with hammer until flush with fixture, then drive pin until flush with top of head. Answer #2 Book Answer: Concrete fasteners are designed to remain fixed in base material once they are set. Concrete and masonry fasteners are unique. They are placed into a drilled hole in concrete, brick or block. Once set, it is not possible to remove them without damaging the base material that they are set in. The base material is the weakest link when working with concrete and masonry fasteners. If pulled on hard enough, the base material will fail and the anchor will become detached. This will leave a hole in the concrete that is the shape of an upside down cone. The amount of force required to remove the anchor is called the ultimate pullout or ultimate tension load. The pullout value is determined by the diameter of the anchor and the depth of embedment of the concrete anchor in the base material. Also, each type of fastener has a different holding value for the same diameter and depth of embedment.
