        for 1/4 inch do you use a 3/16 concrete bit like with other types?

        Answer This Question

        No, for Hammer-Set anchors, you would use the same drill bit diameter as the anchor itself. In this case, use a 1/4" diameter drill bit. If you have any further questions, please contact customer service at 1-877-489-2726.

            Lead 1/4" anchors
            These 1/4"x1" lead anchors are amazing. Their versatility is amazing. Drilling in concrete requires a 1/4" mason bit. Minimal effort to hammer down and secure anchor. In the event of a mistake, the ability to be removed and drilled in another is super easy. Whether your hanging or securing something vertical.or horizontal is effortless. Highly recommond for either commercial or resdential applications.

            Simple and effective concrete anchor
            Product is a hammer in wall anchor for use in concrete, where the anchor expands as the nail is driven in. It does require to pre drill the hole, but has advantages over actuated or plastic wall anchors. Not everyone has an actuated nailer and these anchors only require a drill, masonry bit, and a hammer. Tested out and the nail sets flush with the collar.

            Simple to use, strong
            These hammer-set anchors are great. Just drill a hole a little longer than the anchor, put the anchor through the item you’re attaching, and give it a couple sacks with a hammer. I used it to attach a clip to cement that my wrought iron fence attaches to. It held it perfectly tight and looks much better than a bolt head sticking out. It has a nice smooth finish.

            Easy Installation
            These anchors work well in brick and concrete, but also work OK in softer materials too (wood) if you don't want to use screws for some reason. They are holding up some signs at the moment and were easy to install. The photos show what the original unused anchors look like and then what a fully pounded in one looks like, so it is clear where the expansion of the anchor takes place.

            sure hang
            These nails worked great for our cement brick wall where we are trying to hang our clock. we've tried other nails to hang on the cement brick but nothing usually things will stick for a little bit then fall. these anchors nails are strong, sturdy and work like drywall anchors that ensure nothing will slip out or fall out of the cement. looking forward to being able to hang more items with these.

            Redhead Zap-its Nail Anchors are great
            I will use these around my garage to secure equipment and angle to the concrete. This bucket of 225 pcs. will last me a long time. I've used these many times over the years. The 1/4" x 1" Redhead brand Nail Drive Concrete Anchor has been a go-to product for most contractors because of its simplicity of installation. The way I install them is as follows; drill a 1/4" hole into concrete, put the anchor into whatever you want to attach (bracket, angle iron, etc.), push into the 1/4" concrete hole and hammer away until the nail is flush. On the 1" anchors you can only anchor a 1/4 thick piece due to needing to drill 3/4" min into the concrete.

            These anchors nail make it easy to build my kitchen wall.
            This is a large pack of 1/4 in x 1 in concrete anchors and has enough weight & is very strong. I use this nail for my basement with metal studs to build the wall. To use these concrete anchors was easy. I use the drill to have a hole and then use a hammer on the nail. This is the best use as a DIY person and makes my work very easy and comfortable. I built my kitchen wall with those nails and this was very convenient to the nail as a DIY person.

            Its A Bird, It's a Redhead For all Occasions
            Attaching Metal shelving to a concrete block can be any simpler or more secure than using a Hammer Set Redhead. Drill the correct pilot hole, align the piece to be mounted and hit the head with preferably a milled face hammer. I have used redheads for over 30 year or so and have never found a better solution to mounting, securing, holding down any object.

            Red Head Hammer-Set work great
            Anchored light poles in paver brick as well as electrical box in brick. Drilled 1/4" holes in paver with hammer drill, press anchor into hole and hit nail down with a hammer. Nothing could be faster. Did the same to mount a portable generator receptacle enclosure to brick. There is one thing to be aware of that removal will be a problem unless clear access is available from the side. Believe you would have to drill off the nail head to remove when you cannot pry from the side.

            I used this product in a Oregon hyperbaric chamber office. I needed a product that would hold inch and a half pipe 20 ft lights at a time on a cement tilt wall. This product secured face plates everything 8 feet, horizontal and vertical. Not a problem and plenty strong. Easy as drinking a 1/4 inch hole. Insert pin and hit with a hammer. That causes the product to spread in the wall and secure heavy items. I have even used them on ceiling installation projects. Meets all weight items and look neat for inspector.
