Nail Gun Nails: Complete Guide to Types, Sizes, and What to Use When

Not all nail gun nails are the same — and using the wrong nail in the wrong nailer, or the wrong nail for the application, causes problems that range from jams and misfires to failed inspections and callbacks. This guide covers every major type of nail gun nail, how sizes work, what collation and shank types mean, and how to match the right nail to the job.

Types of Nail Gun Nails

Each type of pneumatic or cordless nailer is designed around a specific nail. The nails are not interchangeable between nailer types. A framing nailer magazine won’t accept roofing nails, and a brad nailer won’t fire finish nails. Here’s how each category breaks down.

Framing Nails

Framing nails are the largest common nail gun nail, designed for structural wood connections: stud-to-plate, header, rim joist, and sheathing applications. They drive 10d to 16d nails, most commonly in 3-1/4” (10d) and 3-1/2” (16d) lengths.

Common framing nail sizes:

·      2” — light structural connections, blocking in tight spaces

·      2-3/8” — sheathing and lighter framing

·      3” — standard framing, engineered lumber connections

·      3-1/4” (10d) — stud-to-plate, standard wall framing

·      3-1/2” (16d) — double plates, heavy headers, ledger connections

Framing nails come in 21-degree and 30-degree collated formats (more on collation below). They’re also available in smooth shank, ring shank, and screw shank — shank type matters for code compliance and withdrawal resistance.

Roofing Nails

Roofing nails are short, wide-head nails designed specifically for roofing shingles, underlayment, and roofing felt. The large flat head is what distinguishes them — it holds roofing materials securely without tearing through them.

Roofing nails are almost exclusively used in coil roofing nailers, which hold 100–120 nails in a coil magazine for high-speed production on roofing applications. Standard roofing nail sizes are 1-3/4” and 1-3/4” to 1-7/8” for standard 3-tab and architectural shingles, though local code may require specific lengths and shank types.

Roofing nail types:

·      Smooth shank — standard for most residential shingle applications

·      Ring shank (screw shank) — required by code in many high-wind zones; greater withdrawal resistance

·      Galvanized — required for all exterior roofing applications to prevent corrosion

Finish Nails

Finish nails are 15-gauge or 16-gauge nails used for trim, molding, door and window casing, and cabinet work. They’re larger than brad nails, leaving a slightly bigger hole, but they have significantly more holding power — appropriate for heavier trim and hardwood applications.

Common finish nail sizes:

·      1” — thin base molding, small trim details

·      1-1/4” — standard casing, base molding

·      1-1/2” — heavier casing, door and window trim

·      2” — thick trim, crown molding, stair rail components

·      2-1/2” — heavy hardwood trim, thick substrates

Finish nailers typically accept 15-gauge (angled, with higher holding power) or 16-gauge (straight magazine) nails depending on the nailer model.

Brad Nails

Brad nails are 18-gauge nails which are thin enough to leave minimal surface marks on trim and delicate wood. They’re used for lightweight finish work: thin casing, cabinet face frames, wainscoting panels, and anywhere you need to minimize the visible nail hole.

Common brad nail sizes:

·      5/8” — very thin trim, small molding details

·      1” — standard face-frame assembly

·      1-1/4” — trim over thin substrates

·      1-1/2” — standard casing and baseboard on drywall

·      2” — thicker trim, attaching over thick material

·      2-1/8” — maximum length in most 18-gauge brad nailers

Brad nails are not appropriate for structural or high-stress applications. They’re a finish-only fastener.

Coil Nails

Coil nails are not a separate nail type by application, they’re a collation format. Coil-collated nails wind into a round magazine rather than a straight strip, which allows a much higher nail capacity per load (typically 120–300 nails vs. 60–80 for strip nails) and a more compact nailer body.

Coil nails are used in coil framing nailers and coil roofing nailers. For framing applications, coil framing nails are available in the same sizes as strip framing nails. Coil roofing nails are the standard format for roofing nailers.

Nail Collation Types

Collation refers to how nails are held together in the magazine. Choosing the right collation is not optional, you must match the nail’s collation type and degree angle to your specific nailer model.

Strip vs. Coil

·      Strip nails load into a straight or angled magazine. They typically hold 60–80 nails per load.

·      Coil nails load into a round drum magazine. They hold 120–300 nails per load which means significantly fewer reloads on high-volume work.

Degree Angle (Framing Nails Only)

·      21-degree — full round head nails, plastic collation. Required for structural applications under many codes (shear wall framing, hurricane-rated connections).

·      28-degree — wire-collated nails, compact magazine. Less common.

·      30-degree — clipped or offset-round head, paper or plastic collation. More compact magazine, easier access in tight framing. Check local code before using clipped-head nails on permitted structural work.

Paper vs. Plastic Collation

·      Paper tape — burns away cleanly on firing, leaves less residue, often preferred for interior work

·      Plastic collation — more durable in wet conditions; small plastic strips remain after firing (minor cleanup consideration)

Nail Shank Types

The shank is the body of the nail. Shank type directly affects holding power and is often specified by building codes for structural applications.

Shank Type	Description	Best For
Smooth shank	Plain, unridged shaft	General framing, non-structural applications
Ring shank	Circumferential ridges along the shaft	Sheathing, decking, roofing; high withdrawal resistance
Screw shank	Twisted spiral along the shaft	Highest withdrawal resistance; hardwood, engineered lumber

 

For most residential wall framing, smooth shank is standard. For sheathing, subfloor, and roofing, ring shank is commonly required. Screw shank is used where maximum pull-through resistance is needed like deck ledgers, structural connections in high-load areas.

Frequently Asked Questions

What nails do I use in a nail gun? It depends entirely on the type of nail gun. Framing nailers use 21-degree or 30-degree collated framing nails. Roofing nailers use coil roofing nails. Finish nailers use 15- or 16-gauge finish nails. Brad nailers use 18-gauge brad nails. Always match the nail’s collation type and degree angle to your specific nailer model — the nailer’s manual or product page will list compatible nail specifications.

What size nails do framing nailers use? Most framing nailers accept nails from 2” to 3-1/2” in length. The most common framing nail sizes for wall framing are 3-1/4” (10d) for stud-to-plate connections and 3-1/2” (16d) for double plates and headers.

What is the difference between framing nails and finish nails? Framing nails are large-diameter structural nails (10d to 16d) used for rough carpentry. Finish nails are smaller-diameter (15- or 16-gauge) nails designed for trim and molding where a smaller, less visible hole is important. They are driven by different nailers and are not interchangeable.

What is the difference between brad nails and finish nails? Brad nails are 18-gauge which are thinner than finish nails (15- or 16-gauge). The thinner wire leaves smaller holes with less wood splitting, making brad nails better for delicate trim and thin materials. Finish nails have more holding power and are better suited for heavier trim, hardwood casing, and applications where the nail needs to carry real load.

Can I use any brand of nails in my nail gun? Generally yes, as long as the nail matches the required specifications for your nailer like gauge, collation type, degree angle, and nail length range. Most professional nailers (Milwaukee, DeWalt, Paslode, Senco, MAX USA) accept standard industry-specification nails from any compatible brand. Check your nailer’s specification sheet to confirm compatible nail formats.
