Can I use #10 screws for framing?
For 2x4 framing, the best gauge of a screw to use is a number 9 or 10. As for length, that will depend on how the pieces are connected.
#10 screw: The diameter on a #10 screw is 3/16 inches, and is typically found in 3/4-inch to 4-inch lengths. This screw is used for general construction purposes, such as building decks and storage sheds. #12 screw: Designed for heavy-duty use—we're talking structural framing—a #12 screw is 7/32 of an inch in diameter.
Nails are often preferred for structural joining, including framing walls, because they are more flexible under pressure, whereas screws can snap. Nails are also called upon when securing plywood sheathing for exterior walls, installing hardwood floors, and attaching siding and roofing.
What is this? The ideal depth a screw should go into a stud is 3/4 of the length of the screw's bottom part. Experts say that half of the length is alright. You'll have to consider any material between the screw and the stud.
Common Sizes of Picture Framing Screws Include #6 and #4 Pan Head, and We Carry Both Types of Screws. Be Careful Not To Screw In Hanging Hardware That Is Too Deep For Your Wood Frame. The 3/8" Screws on This Supplies Page Are Good For Small DIY Picture Frames.
| Screw Size | Threads Per Inch | Recommended Hole Diameter for Material with Flexural Modulus of Up to 200,000 P.S.I. |
|---|---|---|
| #6 | 19 | 0.102" |
| #7 | 19 | 0.120" |
| #8 | 18 | 0.120" |
| #10 | 16 | 0.136" |
The number “10” is used as a size designator and has no numerical meaning. “32” refers to the 32-thread pitch in threads per inch. You can identify a 10-32 screw by measuring the diameter with a ruler at exactly 3/16 inches ().
Use coarse-thread drywall screws for most wood studs. Coarse-thread drywall screws, also known as W-type screws, work best for most applications involving drywall and wood studs. The wide threads are good at gripping into the wood and pulling the drywall against the studs.
| Size | Major Thread Diameter* | |
|---|---|---|
| Decimal | Nearest Fractional Measurement | |
| #8 | .164" | 5/32" |
| #9 | .177" | 11/64" |
| #10 | .190" | 3/16" |
Increased Strength
Screws are, in fact, able to create a more secure hold when joining objects than nails because they have a threaded shaft. With that said, nails offer greater tensile strength.
Can I hang a frame with a screw?
Generally screws provide more holding power than nails, so they're better for hanging large, heavy pictures. When hanging a picture between studs, use a hollow-wall anchor, such as a toggle bolt, molly bolt, or spiral anchor.
Nails are required in most places for structural wood framing. In the US if an inspector sees screws in structural walls they will make you take them apart and rebuild them with nails. Screws have better pullout resistance but less shear resistance than nails.
The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4.
Length, Gauge, and Pilot Holes
If the screws are too short, they may not adequately hold the boards together. If they are too long, they will piece through to the other side. Thickness (gauge): Wood screws must be thick enough to grab onto the two boards.
To bind to 2x 4 together it is best to use 3” screws in most cases, but 2.5” screws will work too. Always consider the combination of materials you are fastening and think about what could be penetrated inside.
Self-Tapping Screws for Metal Studs
A self-tapping screw is commonly referred to as a “metal screw” since they are frequently used to fasten metallic materials. Self-tapping screws “tap” or cut threads into a metal.
Buying Steel Studs
Use 1/2-in. No. 8 pan-head screws. Most home centers and lumberyards carry only the most popular 3-5/8 in.
Most screws will hold anywhere from 80-100lbs of weight. However, this number can fluctuate based on the screw's length, width, quality, thread type, how it was installed, and the type of impact that the screw has to withstand.
| Screw Size | Hard Wood | Soft Wood |
|---|---|---|
| Tapered Bit | Straight Bit | |
| #10 | 13/64" | 1/8" |
| #12 | 7/32" | 9/64" |
| #14 | 1/4" | 5/32" |
Machine screws are often found in sizes of: 0, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14—the larger the number, the larger the screw. Machine screws, but especially caps screws and bolts, can range from 1/4 inch up to 3 inches or more.

#10 Screw Size & Its Uses
The thread diameter of a #10 screw is 0.19″ or 3/16th of an inch. You will see this type of screw used in many construction jobs.
Use three 3" screws for 2x6 headers, four for 2x8, etc. Like laying out walls and joists, use two 3" screws for each 2x4 intersection. If two or more studs are parallel to each other, screw them together every 24".
#10 General construction, heavy-duty furniture, outdoor projects, decks, lawn furniture, boat building, etc. Available in 3/4 in. to 4 in. lengths.
I usually use anything between 70-90mm screws. I generally use 5x80/90mm for stud work. Yes be careful, I have cut plenty of floors up where the pipe work is tight up to the underside of the flooring.
Whether fastening a framed picture, mirror, shelf, or curtain rod to a wall, it's always best to screw or nail directly into a wall stud. Unfortunately, studs are seldom, if ever, positioned exactly where you need them, but that's okay.
| Size | Dia. | Lubricated Parts K=.15 |
|---|---|---|
| MinBreak Str, (in/lbs) | ||
| 8-32 | 0.1640 | 15.5 |
| 10-24 | 0.1900 | 22.4 |
| 10-32 | 0.1900 | 25.7 |
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".
When choosing a screw length it's important to remember that the nail should always be three times as long as the thickness of the material in which it will be driven into. To find this: hold the screw up against the piece you're putting it through and select a nail approximately three times the thickness.
Nails are a favorite for large jobs in construction because they're cheaper than screws and offer shear strength — or the ability to withstand shear pressure, where two surfaces slide past each other. But screws offer superior tensile strength over nails.
What screws should I use for a deck frame? For your deck framing, we recommend stainless steel screws or coated steel structural screws.
When did Carpenters stop using square nails?
Square nails were used in construction until the late 19th century.
To avoid damaging your walls however, read our article on how to hang pictures without nails. For pictures that weigh more than 10 pounds, you'll need to use a wall stud, a rail track, or learn about the different hanging solutions below.
Drywall screws are not usually long enough or thick enough for putting together frames . Framing screws want to be a minimum of 75 mm or 3 inch , ideally 100 mm or 4 inch and 4.5 to 5 mm in diameter , this gives adequate length and strength of the screw to hold a frame together tight and rigid .
Non-load bearing is the critical phrase. You cannot frame bearing walls with screws.
As long as they are normal screws and you unscrew them they won't compromise the studs or their integrity. If you rip the screws out (with a hammer for example) that could compromise the studs.
Machine screws are often found in sizes of: 0, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14—the larger the number, the larger the screw.
The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw's diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you'll want to go with a #8 screw.
Wood-framed houses have traditionally been built with 2x4 studs spaced 16-inches on-center.
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".
10-32 threads are designed into Dell Equipment and most audio racks. 12-24 is more common than 10-32. 12-24 fasteners are slightly larger than 10-32 and have courser threads. The term 12-24 comes from the Unified and American Screw Threads for Bolts, Nuts, and Machine Screws standards published by ANSI B1.
