Buy a Variety of Physical Screw Lengths
Buy a variety of lengths and then you have the right spiral size on mitt. Select a spiral length to penetrate the concrete at least one in. Add i in. to the thickness of the material y'all're attaching to get the minimum length of screw needed. In hard, dense materials similar concrete or stone, this minimum i-in. screw embedment volition work fine. Merely for maximum strength, use longer screws, up to 1-3/4 in. embedment, in soft brick or other less dense materials. You may accept to experiment with a few dissimilar lengths to detect a screw that you can drive fully and that holds securely.
You'll find blue concrete screws at domicile centers, hardware stores and lumberyards, or you tin order them by telephone or on-line. Screws are bachelor in several lengths in packages of 8 or 25 and in boxes of 100. The more you lot buy the cheaper the price. A drill bit is usually included in boxes of 25 or more. Information technology's worth having a couple of spiral sizes on mitt if you do a lot of projects.

Make Sure to Drill the Pigsty Deep Enough
Holes for concrete screws should be at least one/4 in. deeper than the screw will penetrate to allow a little extra space for dust accumulation from the drilling process. See the analogy above. But it's not always easy to judge how deep you're drilling. Too shallow and the screw won't go in. And drilling deeper than necessary is a waste matter of fourth dimension and endeavour. That'southward why most hammer drills come equipped with an adaptable depth stop.
Troubleshooting
If you're having trouble driving the spiral all the mode, first make sure the pigsty is deep enough. If information technology is and you lot're still having trouble, there's probably also much grit in the hole. Remove the screw and clean out the pigsty by running the bit in and out a few times. Try driving the spiral again. If information technology's still stubborn, back it out and redrive it a few times. If all else fails, install another screw a few inches away. Finally, consider a niggling shorter spiral for the remainder of the holes.
Sometimes you'll take the opposite problem. The screw will spin without gripping. If this happens, the material you're fastening to is probably too soft or crumbly. Try a longer screw, or if you're using a three/16-in. screw, try a 1/4-in. bore. Y'all may accept to use a concrete ballast that expands as yous tighten the fastener.

Choose three/16-in. Screws for Virtually Light- to Medium-Duty Tasks
Home centers and hardware stores stock physical screws in two diameters, iii/xvi in. and 1/4 in. The iii/16-in. diameter screws are plenty strong for most dwelling house tasks like installing furring strips, screwing down walls to concrete floors, and attaching hardware to block or brick. And since they're a piddling cheaper and the smaller hole is easier to drill, the iii/xvi-in. size is usually the better choice. If y'all're having problem with the three/16-in. screws snapping off because the concrete is besides hard, switch to stronger one/four-in. diameter screws instead. You could also go along some 1/4-in. screws handy in case you strip out the hole for a three/16-in. spiral. Switch to 1/4-in. screws for heavy-duty piece of work like securing a wall cabinet to a concrete or block wall, or supporting shelving that volition hold a lot of weight.

Apply a Hammer Drill
In some less dense materials like soft brick, yous tin drill airplane pilot holes using a carbide-tipped fleck in a regular drill. Just in most cases, you'll need a hammer drill. Corded hammer drills cost $65 to $400, or you can purchase a cordless model starting at $230. You can also rent hammer drills for about $35 per 24-hour interval.
Precisely sized carbide-tipped bits are often included with packs of screws, or you lot can purchase one separately. Match the bit to the size screw you're using: 5/32-in. bit for 3/16-in. screws and 3/sixteen-in. diameter bit for ane/iv-in. Go along a spare chip on paw, since the tip tin wear out rapidly in some difficult materials, resulting in a hole that's likewise small. Ane indication of a worn bit is screws that are difficult or impossible to drive completely.

Use Hex Caput Screws Where Advent Isn't an Issue
Concrete screws are available with either flat head Phillips or hex heads. In situations where the screw head must exist affluent to the surface (furring strips nether drywall), or where a Phillips head would wait nicer, apply the Phillips head screws. Otherwise, e'er selection the hex head screws. The positive date of the hex bit makes them easier to drive (see photo, p. 35).You'll demand a i/4-in. hex driver for the three/16-in. screws and a 5/16-in. hex head driver for the thicker one/iv-in. screws.
When y'all're using Phillips head screws, go on extra No. two (No. 3 for 1/iv-in. screws) Phillips head bits on manus. The hardened screws wear out $.25 quickly.
Screw Heads and Usage
Bulldoze Phillips head screws where a flush surface is required and where a Phillips head would look amend. Otherwise utilise hex head screws.

Drill With a Firm Hand and Maintain Steady Pressure
Adept technique is essential for driving physical screws. Not enough downward pressure and the fleck could slip off the head, especially if you're using Phillips head screws. For the best results, continue constant pressure on the screw and run the drill at slow to medium speed.
It takes a light touch to avert snapping screws. Heavy-duty drills work best because they can maintain a steady dull speed. End as shortly as the screw is affluent to the surface and your material is firmly fastened. Driving at high speeds results in overdriving the screw and can strip the threads or break off the head. You lot'll develop a feel for the right amount of speed subsequently driving a few screws.
Stopping Signal
Ease off the driving speed every bit the screw head nears the surface.

Use 2 Drills or Buy an Installation Kit to Speed up the Job
Install the masonry scrap in your hammer drill and a driver bit in a variable speed drill. And so you won't have to switch bits constantly. Another option is to buy an installation tool. Information technology allows you to switch quickly from drilling to driving mode and back again, and includes Phillips and hex head $.25 to bulldoze both 3/xvi-in. and 1/iv-in. screws. We constitute an installation kit alongside the concrete screws at the home center.

Keep a Handful of Plastic Anchors in Case of Strip-Out
Occasionally the threads of a screw won't grip and the screw will spin in the hole. Usually you can just abandon this hole and drive another spiral a brusk distance away. Simply if relocating the screw isn't a good option, simply enlarge the hole and slip in a plastic anchor. And so drive the physical spiral into the ballast.
Sleeve Anchors for Concrete Block
Fastening heavy items to physical cake is simple if you utilize the right tools and fasteners. Where most people mess up is in thinking they can use plastic anchors. Uh, no. At the very least you should employ a lag shield, merely fifty-fifty and then, you tin can use that type of anchor only when mounting to 1 of the three solid sections of the block.
Sleeve anchors are a meliorate option because they piece of work in the solid and hollow sections of the block, too as the mortar joints. Here are two important tips when you're installing sleeve anchors.
ane. Leaving drilling dust in the hole will reduce the fastener'due south holding power. And so remove it with a vacuum or blower. A baby's ear syringe (about $5 at any drugstore) works great for this (keep one in your toolbox). Just shove it into the hole and puff out the dust.
two. Protect the bolt threads by unscrewing the nut until it extends slightly by the bolt threads. Then drive it dwelling with light hammer blows.
