Drywall Screws
The defining feature is the bugle head: a curved underside that presses a shallow dimple into the paper without breaking it, so the joint compound can cover it flat.

Drive types
Choosing the thread
-
Coarse
For timber framing. Larger pitch to grip wood fibre.
-
Fine
For light steel framing. Smaller pitch so the thread does not collapse cutting thin steel.
-
Hi-lo
Alternating thread heights reduce driving torque; used in thicker or harder substrates.
Where it most often goes wrong
Each of these causes scrapped lots or rework on the floor. None of them is theoretical.
Coarse and fine swapped. The most common error on site. Coarse into steel framing will not hold; fine into timber has insufficient grip.
Length chosen from board thickness alone. What the code fixes is not the screw length but the penetration past the board, and it gives three different minima depending on what you are screwing into. IRC R702.3.5.1: not less than 5/8 in into wood framing, not less than 3/8 in into cold-formed steel thinner than 0.033 in, and not less than 7/16 in into the facing of structural insulated panels. The softer the material, the deeper the screw has to go — 5/8 against 3/8 is a ratio of about 1.67. It also names the screw: Type W or Type S to ASTM C1002 for wood, minimum No. 6 for steel framing, and ASTM C954 once the steel runs 0.033–0.112 in.
Assuming the code sets a service life. It does not. Searching the whole chapter for "pop" returns nothing — the code governs installation, not how long the result stays put. And it is a US model code with no legal force until a jurisdiction adopts it, usually with amendments. What the spacing table actually permits, including the row where screws and nails are allowed the same spacing.
Driven through the paper. Once the paper face is broken that screw has no holding power and filler will not hide it. Use a depth-limiting dimpler bit.
Used structurally. Drywall screws are brittle — hardened for driving, with poor shear and tensile capacity. They hold board. They do not hang loads or make structural connections.
How length is measured
One rule covers it: if the head sinks into the work, measure overall; if it stays on the surface, measure under the head.
| Head style | Datum | Why |
|---|---|---|
| Countersunk (flat) | Overall length | The head sits flush in the countersink, so it counts |
| Oval (raised countersunk) | Overall to the head diameter | The cone sinks, the dome stays proud; measure to where they meet |
| Pan / round | Under head | The head stays entirely on the surface |
| Button | Under head | Same |
| Hex / hex washer | Under head | Same |
| Socket head cap | Under head | Same |
