Concrete Fasteners & Anchors

Concrete Fasteners and Anchors - Part 2

Applies to concrete, brick, block, stone & mortar.

Anytime that you need to fasten something, be it racking, cabinets or other objects to a wall, floor or ceiling made from concrete you must consider the best method to anchor it. One of the most common errors made by the diy home handyman is to look in his glass jars to find a fastener that "might" work. After spending countless hours and dollars on a home improvement project skimping on the fasteners is foolish to say the least.

Figure 1 - Selection of concrete anchors

There are hundreds, if not thousands of fasteners and anchors designed for mounting items to concrete.

In this review we will attempt to cover the most popular fasteners and describe their differences. By no means have we listed every concrete fastener or anchor that exists and there may be some that have been left out that have benefits that the ones we have listed do not.

It should also be noted that many manufactures make the same basic fasteners and anchors and although there are some subtle differences, in order to differentiate their products, the end result, in most cases, will be similar.

The reader should not assume that the position in the list represents the quality of the product. The items are listed randomly and their position should not be taken to imply anything what-so-ever.

Concrete Anchors & Fasteners
	Identification	Features	Base Material	Application
	Drop-In Anchors:	Available zinc plated, 304 and 316 stainless steel. The slots in body allows for uniform expansion of anchor. Excellent for applications that require flush mounting.	Concrete	Medium to heavy-duty into solid concrete. Dead loads only.
	Wedge Anchors:	Standard zinc plated Hot-dipped galvanized for excellent rust resistance Stainless steel for superior rust resistance.	Solid Concrete	Heavy-duty.
	Strike Anchors:	Made from carbon steel. Plated with yellow dichromate over zinc. Drive pin is hardened steel. No special tools needed to set anchor, just a hammer. Nut and washer can be preset for desired embedment. Nuts and washers are included.	Solid Concrete	Medium to heavy duty
	Lag Shield Anchors:	Short lag shields may be used in hard masonry to help cut down drilling time. Long lag shields are used to develop excellent holding values in softer base material. Rust-resistant zinc die cast alloy Can not be over expanded	Concrete Brick Block Stone Mortar	Medium to heavy duty. Dead, variable or vibratory loading.
	Tapcon® Concrete Screws:	Fast installation... drill a hole... drive an anchor. Replaces small diameter expansion anchors, plugs and screws in light to medium duty applications. No need to pre-spot holes....and no inserts are required. Reversible and removable....can be installed close to an edge.	Concrete Brick Block Stone	Light to Medium Duty.

Split Drive Anchors:

Made of high strength, heat-treated alloy steel.
Two head style, flat countersunk and round head.
Tamper resistant.
To determine anchor length: add minimum embedment 1-1/8” plus thickness of material to be fastened.

Solid Concrete

Light duty.

Dead loads only.

Hurricane Shutter Insert Anchor:

Hurricane shutter insert anchors provide a non-protruding and high-strength connection for anchoring hurricane shutters.
This anchoring system introduces a new anchoring concept designed to anchor to concrete or block.
