What kind of screws to join cabinets together?
To attach the cabinets to each other, use a No. 8 2¼-inch-long trim-head screw with a fine thread suited for hardwood. This fastener's small-diameter head is unobtrusive, so you don't have to hide it under a cap or wood plug.
GRK Trim Handy 8 x 2½” Head Screw
For many carpenters, GRK makes the best cabinet screws in the market. If you need cabinet screws for joining cabinet face frames, you should consider the GRK Trim Handy 2½” Head Screw.
When connecting two cabinets to each other, line up the face frames and clamp them together. Both cabinets should be fastened to the wall at this point, but you may have to loosen one cabinet or the other to get the frames to line up perfectly. Hand-screw clamps don't flex, and less flex means a tighter grip.
Attach the cabinets to the studs with at least two screws in each mounting rail, while attaching the cabinets to each other with at least four drywall screws. Once all cabinets are securely in place, trim off the exposed shims with a utility knife.
For gaps less than 1/8-inch, it's acceptable to use colored caulk or other products that come in a tube. If you plan on refinishing the cabinets, you can also use wood putty that dries hard to fill gaps or cracks. If the cabinets do not need finishing, apply color-matched caulking to the gaps.
For frameless cabinets:
Once cabinets are joined, it's a good idea to pre-drill holes in the mounting rails at the back of each cabinet and drive screws partially in. Two #10 2-1/2-in. or 3-in. wood screws will do the trick. Don't use drywall screws; they don't have enough shear strength.
Screws are also measured in diameter, known as the gauge. The range of gauges is from 2 to 16, with a #8 gauge being the most commonly used. The thicker the material, the thicker the gauge you'll need. For very heavy cabinets, you might need screws with a gauge of 12 or 14.
They'll be sturdy and long-lasting. You can even assemble them alone, if you like, though you'll need a friend to help hang the wall cabinets. Still, if you want just that little extra bit of finesse, a little wood glue in the seams will help extend their longevity, making extra sure they never shift.
Add Trim EVERYWHERE
You can hide the horizontal joint between 2 cabinets with a pretty chair rail molding. That pretty chair rail hides the horizontal joint where 2 different cabinets connect. Trim out the bottom edge of upper cabinets with trim to give that cabinet look more like furniture.
(On some wall cabinets, the mounting rails are inside the cabinet. On others, they are hidden in back.) Drive 2 1/2-inch cabinet screws through the holes and into the studs.
Are cabinet screws strong?
These screws are made of hardened steel, which makes them very strong; they will also break if you overtighten or bend them. I've never seen them fail. I used them to install my own cabinets over 20 years ago and they are still on the wall.
One of the steps that we do on about 50% of the cabinets that we paint is to caulk the seam between the door panel and trim. The idea is to make the caulking smooth, consistently even in the roundness of its cove, no gaps or ridges, and also to blend in seamlessly with the grain on the panels.
Tim Inman: One-quarter inch OVERALL would leave you with a one-eighth inch gap all around. That's about right. If you make the gap much bigger, it looks like sloppy work. If you make it any smaller, you'll end up with binding doors.
There are three potential reasons why your cabinets fell. Either the cabinets weren't fastened to the wall studs, the fasteners were inadequate for the task, or you have no studs at all—just a brick wall covered with plaster.
As you start to get your cabinets in place and leveled, you'll want to secure any adjacent cabinets together. Ikea provides screws for doing this, but you'll want to use some clamps (we like these 6″ bar clamps) to hold the cabinets tightly together before you begin screwing.
Hang the Upper Cabinets
If it is, drive four 2½-inch deck screws (with washers) through the back of the cabinet, top and bottom, and into the studs. If it's not, slip shims between the cabinet back and the wall at the stud locations.
Cabinets often contain strips of wood near the top and bottom that should be used to hang the cabinets. Make sure that you drill holes through these pieces of wood. Apply screws. Drive two-inch or three-inch wood screws through the pilot holes into the studs.
Buy a Set of Countersink Bits
The pilot hole bit creates a hole that reduces friction to make screw driving easier, and the countersink allows you to set the screw head flush with or below the surface.
The general rule is that two thirds of the length of the screw should penetrate into the lower piece. For example, if the upper piece is 3⁄4" thick, I use a screw that penetrates twice this thickness (11⁄2") into the lower piece. The total length of the screw should be in the range of 21⁄4".

What type of screws are used to fasten cabinets to walls with steel frames?
In buildings that have steel wall frames, metal screws need to be used.
To make your IKEA furniture look more professional and expensive, use glue during assembly. When applied correctly, the glue will prevent wobbling and make for strong, good-looking furniture that will last for many years. Assembly experts recommend using either white Gorilla glue or Gorilla construction adhesive.
hinge screws with at least two 3-in. screws that go through the jambs and solidly anchor into the framing. If the door has a large hinge with four screw holes, just drive 3-in. screws straight through the two holes toward the center of the door.
The standard screw size typically recommended for most residential door hinges is #8 x 1-1/2 inch or #10 x 2 inch wood screws.
The standard hinge screw size for a residential door hinge is No. 9 screw. They are hinges used for main doors and entry doors to houses.
The PowerHead Screws for Metal have more holding power, finer threads, and a drill-point head to easily tap into steel studs for maximum holding power. The PowerHead Screws main advantage is its large, oversized flat head that won't pull through your attaching material.
A woodscrew, on the other hand, is meant for wood. A deep-thread wood screw (or particle board screw) is for pressboard, and so on. A cabinet screw is typically a screw that comes with a modified truss head that has a larger bearing surface and in particular, no countersunk head.
What usually looks best is a pull length that is about 1/3 the height of the cabinet door and 1/3 the width of the cabinet drawer. Your eyes follow the length of the pull up the height of the door or across the width of the drawer. Pulls don't have to all be the same length as long as the pull design is the same.
