CONFAST WAG12234A – Frequently Asked Questions
1) What size drill bit do I need for CONFAST galvanized wedge anchors?
Drill with a bit that matches the anchor diameter. A 3/8 inch anchor takes a 3/8 inch bit, 1/2 inch takes 1/2 inch, 5/8 inch takes 5/8 inch, 3/4 inch takes 3/4 inch, and the 1 inch anchor takes a 1 inch bit. The hole is drilled through the fixture into the concrete at the same diameter as the anchor, which is why the fixture hole has to be slightly larger (for example 1/2 inch clearance on a 3/8 inch anchor when the anchor is set through a fixture already in place).
2) Can CONFAST wedge anchors be used in block, brick, or mortar?
No. These wedge anchors are rated for solid concrete only. Hollow block, brick, and mortar joints need a different anchor type, such as a sleeve anchor or a screw anchor rated for masonry, because a wedge anchor relies on the clip expanding against dense solid concrete to hold.
3) How deep does a CONFAST wedge anchor have to go into the concrete?
Minimum embedment climbs with diameter: 1-1/2 inches for 3/8 inch anchors, 2-1/4 inches for 1/2 inch, 2-3/4 inches for 5/8 inch, 3-1/4 inches for 3/4 inch, and 4-1/2 inches for the 1 inch anchors. Your slab needs to be thicker than that embedment, and the anchor length has to cover embedment plus the thickness of whatever you are bolting down.
4) How close to a slab edge and to each other can I set CONFAST wedge anchors?
Minimum edge distance is 1-7/8 inches for 3/8 inch anchors, 2-1/2 inches for 1/2 inch, 3-1/8 inches for 5/8 inch, 3-3/4 inches for 3/4 inch, and 5 inches for 1 inch. Minimum spacing between anchors is 3-3/4 inches on 3/8 inch, 5 inches on 1/2 inch, 7-1/2 inches on 3/4 inch, and 10 inches on 1 inch. Setting closer than that risks cracking the concrete out and losing the hold, so on narrow curbs or slab edges step down a diameter or relocate the hole.
5) Which wedge anchor length do I order for a 1/2 inch base plate on a concrete slab?
Add your fixture thickness to the minimum embedment. With a 1/2 inch diameter anchor, embedment is 2-1/4 inches, so a 1/2 inch plate needs at least 2-3/4 inches of anchor plus enough stud for nut and washer. The 1/2 inch x 3-3/4 inch covers up to 1 inch of fixture and is the common pick for plate work; the 1/2 inch x 2-3/4 inch only allows 1/8 inch of fixture thickness, so it is too short for a 1/2 inch plate.
6) How tight should I torque a CONFAST wedge anchor?
Maximum installation torque is 25 to 30 ft-lbs for 3/8 inch, 50 to 60 ft-lbs for 1/2 inch, 75 to 90 ft-lbs for 5/8 inch, 150 to 175 ft-lbs for 3/4 inch, and 250 to 300 ft-lbs for 1 inch. Use a torque wrench rather than an impact gun. Over-torquing pulls the stud through the expansion clip and the anchor stops holding.
7) What thread size are CONFAST wedge anchors so I can match nuts and washers?
The threaded stud is standard UNC coarse thread: 3/8-16 on 3/8 inch anchors, 1/2-13 on 1/2 inch, 3/4-10 on 3/4 inch, and 1-8 on the 1 inch anchors. Each anchor ships as a male threaded stud with its own nut and washer, and any off-the-shelf coarse-thread nut in that size will thread on if you need to double-nut or add a leveling nut.
8) Are galvanized wedge anchors OK for outdoor or wet locations?
The galvanized coating is rated for damp locations, which covers exteriors under cover, loading docks, parking structures, and mechanical rooms. For continuous submersion, pool decks, or coastal salt spray, step up to a stainless wedge anchor instead of galvanized.
9) Can I remove a wedge anchor later if the equipment gets relocated?
No, not intact. A wedge anchor is a permanent expansion anchor: the clip flares against the wall of the hole as the nut is tightened and it will not come back out. If the fixture may move, the usual approach is to cut or grind the stud flush and patch, or use a removable option such as a machine screw anchor with a threaded insert instead.
10) Are CONFAST wedge anchors made in the USA for Buy American or federal jobs?
Country of origin is the US. Every anchor in the CONFAST galvanized wedge anchor line is domestically manufactured, which is what agency and institutional buyers usually need documented on public work. Note that the requirement itself is set by your contract, not by the product.
11) What wrench or socket size fits the nut on these wedge anchors?
Nut sizes are 9/16 inch on 3/8 inch anchors, 3/4 inch on 1/2 inch, 15/16 inch on 5/8 inch, 1-1/8 inch on 3/4 inch, and 1-1/2 inch on 1 inch anchors. Worth checking before you go up in diameter, since the bigger sizes need a deep socket and a breaker bar to reach the required torque.
12) How many CONFAST wedge anchors come in a box?
Box count drops as diameter goes up. The 1/4 inch sizes come 100 per box, 3/8 inch 50 per box, 1/2 inch and the shorter 5/8 inch sizes 25 per box, longer 5/8 inch and most 3/4 inch 20 per box, the 3/4 inch x 7 inch and longer 10 per box, and the 1 inch sizes 5 per box. Anchors are sold by the box, not individually.
