Anchor Bolts and Screws
Anchors are used to attach fixtures to hollow walls or concrete. There are many different kinds of anchors, each with different functions or methods used to anchor themselves to materials. Most notable are Masonry Anchors consisting of Wedge Anchors, Sleeve anchors, and Tapcon Concrete Anchors. Masonry anchors are also known as masonry bolts, concrete anchors, concrete bolts and anchor bolts.
Concrete masonry wedge anchors are used to anchor and secure material and equipment to solid concrete masonry surfaces (ex. concrete slabs). Comprised of an anchor, a nut and a washer. When the nut is tightened, the tapered end expansion expands the anchor, securing it in concrete. Used to fasten concrete to equipment, materials, generators, motors, pumps, pipe, strut, plastics and wood.
Masonry Sleeve Anchors are used for Hollow Concrete Masonry units such as concrete or cinder blocks. Concrete masonry sleeve anchors consist of a threaded stud with an outwardly flared cone-shaped end, with a nut and a washer on the end. Tightening of the nut pulls the stud end into the expander sleeve, wedging it outwards and locking the anchor into the base material. Sleeve anchors are inserted into pre-drilled holes and then they can be expanded for a secure fit, anchoring objects to the concrete, brick, or block. Sleeve anchors work on the true expansion principle: turning the nut on the sleeve anchor pulls the working end of the anchor up through the sleeve, expanding the anchor and causing the anchor to secure itself to the concrete, brick, or block.
Tapcon Concrete Anchors
The "original masonry" anchor that cuts its own threads into concrete, brick, or block. Extended corrosion protection is gained from the blue climaseal coating. No hole spotting or inserts required.
Maximum performance is achieved because the Tapcon Anchor, the Condrive
Installation Tool, and the carbide-tipped Tapcon Drill Bits are
designed to work as a system. It is essential to use the Condrive
® tool and the correct drill bit to assure consistent anchor performance.
Toggle spring wing anchors are anchors used in hollow wall applications (walls with space on the other side) such as drywall and concrete blocks (also called cinder blocks) or any hollow concrete masonry unit. Toggle wings are used with machine screws through pre-drilled holes. The toggle spring wings are folded and inserted through the pre-drilled hole. The spring action of the toggle wings causes the wings to open up inside the wall once clear of the hole it was inserted through.
Hammer Drive Pin Anchors
Used in lighter load applications, Hammer Drive Pins (or just drive pins) attach fixtures to solid concrete or certain types of concrete blocks. Using a predrilled hole, they are installed with hand tools, typically a hammer strike, to drive the pin into the anchor body expanding the anchor to form a tight fit. The washer on the anchor retains the pin and guides it during the driving installation.
