Brad nails are the thin 18-gauge fasteners that hold trim, molding, and cabinet face parts without splitting delicate wood, and their tiny heads leave a pinhole that needs little or no filler. The two things to get right are length and coating: short 1 to 1-1/4 inch brads tack small molding, while 2 inch brads reach through thick casing, and interior bright-coated brads must never go outside where they will rust. Brads are a cheap consumable, so an entire trim job costs only a few dollars in nails. We compare an inexpensive all-purpose strip, a chisel-point brad that resists splitting, and a glue-collated brad that boosts holding power, all in the straight 18-gauge collation that fits nearly every brad nailer.
Grip-Rite's GRF182M is a 2 in, 18-gauge electrogalvanized brad nail, the default interior consumable for trim, molding and cabinet face work. It's cheap at about $15 per 1,000, the straight strips fit nearly every brad nailer, and the pinhole needs little filler. But 18-gauge has low holding power (tacking only), and the coating is interior-only.

- Molding
- Cabinets
Pros
- Cheap consumable at roughly $15 per 1,000, so a full trim job costs a few dollars in fasteners
- 18-gauge leaves a pinhole that needs little or no filler, ideal on stained or delicate molding
- Straight 18ga strips fit almost every brad nailer (Ryobi, DeWalt, Metabo HPT, Milwaukee) with no adapter
Cons
- 18-gauge has low holding power, so it is for tacking trim, not structural or load-bearing work
- Electrogalvanized coating is for interior only, it will rust on exterior or treated lumber
- 2 in maximum length in this SKU cannot reliably bite through thick casing into a stud
A reliable 1-1/2 in interior brad in DeWalt's straight 18-gauge line, with a chisel point that helps prevent splitting on fine molding and casing. It fits DeWalt and other standard straight brad nailers, leaves a fillable pinhole, and is priced as a bulk consumable, making it a dependable default for interior trim where you do not need extra length.
- Trim
- Casing
- Shoe molding
Pros
- Chisel point reduces splitting on delicate molding and trim compared with a blunt point
- Length is well matched to decorative molding, door and window casing, and shoe molding
- Straight 18-gauge strips run in DeWalt 18-gauge brad nailers and other standard straight brad guns
Cons
- Bright coating is interior-only and will rust if used outdoors or on treated wood
- 1-1/2 in length is too short to reach through thick casing into a stud for a solid structural bite
- 18-gauge holds lightly, so it is for tacking trim, not load-bearing joinery
A 2 in glue-collated 18-gauge brad from Bostitch, the extra length reaches through thick casing and baseboard where shorter brads fall short. The coating eases driving and boosts holding power, and the straight strips fit common 18-gauge nailers, making it a good interior choice when you want maximum brad length while still leaving a small, fillable hole.
- Thick casing
- Baseboard
- Trim
Pros
- Full 2 in length reaches through thick casing and baseboard for a better bite than short brads
- Coating eases drive resistance and increases holding power once the nail is set
- Glue-collated straight strips fit a wide range of Bostitch and other 18-gauge brad nailers
Cons
- Coated for interior use, so it will rust outdoors or on treated lumber
- Still only 18-gauge, so for heavy casing and stair parts a 15 or 16-gauge finish nail holds better
- 1000-count box is a smaller quantity, so heavy trim users may prefer a larger bulk pack

Frequently Asked Questions
- What length brad nails should I use for trim?
- For thin base shoe, small molding, and cabinet face work, 1 to 1-1/4 inch brads are plenty. For standard baseboard and door or window casing you want 1-1/2 to 2 inch brads so the nail passes through the trim and bites well into the framing or drywall behind it.
- What is the difference between brad nails and finish nails?
- Brad nails are thinner 18-gauge with almost no head, so they leave a tiny hole and hold light trim without splitting. Finish nails are heavier 15 or 16-gauge with more holding power for thick casing, stair parts, and doors, but they leave a larger hole that usually needs filling. Use brads for delicate work and finish nails where strength matters.
- Will 18-gauge brad nails work in any brad nailer?
- Nearly always, as long as the nail length is within your tool's range. Straight 18-gauge brad strips are a near-universal standard across DeWalt, Bostitch, Ryobi, Metabo HPT, Milwaukee, and Senco 18-gauge brad nailers. Just check that the brad length you buy falls between your nailer's minimum and maximum, commonly 5/8 to 2 inches.
