Choosing Fasteners


Perma Grip Concrete Anchors

Perma-Grip Concrete Anchors For Fastening Lumber To Masonry Material.  For fastening 2x or other material to concrete, block or brick, you may think of Tapcon screws. Another super easy secure alternative fastener for mounting 2x material or other lumber for that matter is the Perma-Grip Concrete anchor.  We have been selling them here in MN for decades, lot’s of them. They are simple to install.  Just drill a 3/16″ hole about 1″ to an 1-1/2″ hole past your desired embement and hammer in.  To determine the correct anchor lenght, add 3/4″ to an 1″ to your material thickness.  So for a 2 x 4, (1-1/2″) add an inch and you come up with the 2-1/2″ Perma-Grip.  For 3/4″ plywood, you would use a 1-1/2″ etc.  We show lengths of 3″ on our site but they are avaialble much longer so if you are fastening something thicker like foam, we can likely supply the correct lenght.  It is important to use the correct length for desired pullout and ease of installation.

The most common application we see is any situation where 2x lumber is fastened to concrete.  For large commercial jobs, the 2-1/2″ size is used fasten 2 x 6 material to the the top of concrete panels.  Perm Grip anchors are also an ideal choice for garge door bucks and window openings.  For multi family structures and basements, you won’t find an easier install than these handly little anchors.  The anchor is covered with an exterior coating making it ok to use with treated lumber and exterior use.

If you are frustrated with Tapcon snapping or stripping (that’s a blog for another day)  Give the Perma Grip anchor a try for fast secure installation.



For years the go to fasteners for poured concrete were wedge anchors. They offer fast relatively fool proof installations.  Wedge anchors are a pretty straight forward install, drill the hole, blow it out, pound in the anchor and tighten.  Your diameter that you drill is the same diameter as the wedge anchor.  For instance, for a ½” wedge anchor you will use a ½” bit.  Drill your hole at least ½” deeper than your intended embedment.  You can drill all the way through the slab if you want in which case if you want to remove the anchor you could remove the nut and pound through.  While diameter as small as ¼” are available, many times a Tapcon concrete screw would make a better choice when you get that small.  Wedge anchors are available in diameters up to 1-1/4” and in standard zinc, mechanically galvanized and stainless steel.

Basics to remember when considering wedge anchors.  Designed for poured concrete, not hollow applications.  Drill bit matches diameter of anchor.  Drill ½” beyond desired embedment. Follow manufacture’s recommended install, usually drill, clean pound in and tighten to recommended torque.  Also follow minimum embedment guidelines.  We stock a complete line of wedge anchors in diamters of 1/4″ to 1-1/4″ .  If you don’t see the size you are looking for give us a call we likely have it. Standard finish is zinc but mechanically galvanized and stainless steel wedge anchors are available.



Choosing the correct fastener when fastening to concrete can be much more than preference.  It can be a safety issue.  While some plans or specs may call out a specific fastener, many situations are left up to the contractor to decide what is best.  In most situations, I actually like it when the contractor has some input on what type of fastener to use as I feel when you mix data, experience and the real world, you will always come up with the best fastener.  Certainly when an engineer calls out a certain anchor or fastener, you want to heed the direction.  Many times you will see the note “or proved equal” so you may have a little leeway to choose a different manufacturer than noted.  There are so many applications, conditions, opinions and methods when it comes to fastening to concrete that it can be difficult to know where to start and where to stop for that matter.  Add to that it really depends on the nature of what you are fastening.  So, we will break it down a little bit by anchor type.
