KYA F15 18 gauge galvanized brad nails are 15 mm straight-strip finish nails designed for compatible 18GA brad nailers. Their compact approximately 1.25 × 1.00 mm wire profile and 2.00 mm head width make them suitable for trim, molding, cabinetry, furniture and other finish woodworking applications where a small fastening mark is preferred.
F15 is approximately 15 mm / nominal 5/8 inch long. This short length is commonly used for thinner trim, cabinet components, decorative molding, picture frames, paneling and similar applications where a longer brad is unnecessary.
The standard product uses an electro-galvanized finish for general indoor and protected-environment applications. Stainless-steel alternatives are available within the KYA brad-nail range for applications requiring greater corrosion resistance; confirm the required material and size when ordering.

18 Gauge: approximately 1.25 mm wide × 1.00 mm thick for fine finish fastening.
15 mm / nominal 5/8" length: short brad size for thinner trim and woodworking components.
2.00 mm head width: compact head profile designed to leave a relatively small visible fastening point.
Chisel point: suitable for controlled penetration into compatible wood, MDF and trim materials.
Straight strip collation: for compatible 18GA straight-magazine brad nailers.
Electro-galvanized finish: provides basic corrosion protection for general indoor and protected applications.
100 nails per stick: matches the magazine capacity of many professional 18GA brad nailers.
5,000 nails per box: suitable for distributors, woodworking shops and production users.

A short 5/8-inch-class brad is useful when the workpiece does not require the penetration of a 1-inch, 1-1/2-inch or 2-inch finish nail. It can reduce the risk of excessive penetration through thin trim, molding, cabinet components and decorative work.
The 18GA profile is smaller than common 15GA and 16GA finish nails. This makes it suitable where appearance matters, although the smaller fastener also provides less fastening capacity than a heavier finish nail.

The standard F15 uses an electro-galvanized surface. This zinc coating provides basic corrosion protection compared with untreated carbon steel and is commonly used for indoor finish carpentry, cabinetry, furniture and other protected applications.
Electro-galvanized brads should not be treated as equivalent to stainless steel or heavier corrosion-resistant coatings for continuously wet, salt-air, highly corrosive or preservative-treated exterior environments.
| Fastener | Typical Use | Selection Consideration |
|---|---|---|
| Electro-Galvanized 18GA Brad | Indoor trim, molding, cabinetry, furniture and protected woodworking. | Economical general-purpose finish where severe corrosion exposure is not expected. |
| 304 Stainless Steel Brad | Moist or exterior applications, cedar, redwood and compatible treated-wood trim. | Greater corrosion resistance than electro-galvanized carbon steel. |
| 316 Stainless Steel Brad | Applications requiring higher resistance to salt air or chloride-rich environments. | Confirm exact size and availability for the required application. |
F15 belongs to the common 5/8-inch 18GA straight brad size class. Many professional 18GA nailers accept 5/8-inch brads, but tool compatibility should be checked by exact nailer model, fastener profile, magazine and head design.
| Tool / Fastener Platform | Published Specification | F15 Selection Guidance |
|---|---|---|
| BOSTITCH BTFP12233 / BT1855 | 18GA BT13XX brads, approximately 5/8"–2-1/8"; BT1300 is the 5/8" size. | F15 falls within the published length class; compare the complete brad profile before cross-brand use. |
| DEWALT DCN680 / DWFP12233 | 18GA brads, approximately 5/8"–2-1/8". | F15 is at the published minimum length; confirm straight-strip profile and head geometry. |
| Metabo HPT NT1850DG / NT1850DFT | 18GA straight brads, approximately 5/8"–2". | F15 is within the published length range; confirm the exact tool model before production use. |
| SENCO F-18XP | 18GA AX / AY style brads, approximately 5/8"–2-1/8". | SENCO AX10EAA is a 5/8" galvanized straight-strip 18GA brad; compare head and strip profile before substitution. |

Several established fastener systems use a 5/8-inch galvanized 18GA straight brad. These references can help distributors and professional users identify the required size class, but they should not be treated as automatic guarantees of interchangeability.
| Reference | Nominal Size | Description |
|---|---|---|
| KYA F15 | 15 mm / nominal 5/8" | 18GA electro-galvanized straight brad |
| BOSTITCH BT1300 | 5/8" / 15 mm | 18GA BT13XX-series brad |
| SENCO AX10EAA | 5/8" | 18GA galvanized, chisel point, straight-strip brad |

| Item | Length | Pcs / Stick | Pcs / Box | Boxes / Carton | Cartons / Pallet | G.W. / Carton |
|---|---|---|---|---|---|---|
| F15 | 15 mm / nominal 5/8" | 100 | 5,000 | 30 | 50 | 20.05 kg |
| F13 | 13 mm / 1/2" | 100 | 5,000 | 30 | 50 | 17.65 kg |
| F16 | 16 mm / nominal 5/8" | 100 | 5,000 | 30 | 50 | 21.37 kg |

One inch equals 25.4 mm, so an exact 5/8 inch measurement is approximately 15.875 mm. For this reason, different fastener catalogs may describe either a 15 mm or 16 mm brad as a nominal 5/8-inch product.
When the exact metric length matters, order by the specific model and millimeter dimension rather than relying only on the nominal inch description. KYA F15 is the 15 mm model, while F16 is the 16 mm model.
| Fastener | General Characteristic | Typical Application |
|---|---|---|
| 18GA Brad Nail | Smaller wire and compact head. | Light trim, molding, cabinetry, furniture and decorative woodworking. |
| 16GA Finish Nail | Larger cross section and greater fastening capacity. | Heavier trim, casing and finish carpentry. |
| 15GA Finish Nail | Heavier finish fastener, often used in angled nailer systems. | Thicker trim and more demanding finish connections. |
F15 can be useful for suitable MDF, thin plywood and composite-wood components because its short length reduces unnecessary penetration. Actual holding strength depends on substrate density, material thickness, edge distance and the direction of the fastener.
For production furniture or cabinetry, test the fastener on the actual board and joint before volume use, particularly when fastening close to panel edges.
Choose the brad length according to the trim thickness and required penetration into the substrate. F15 is primarily a short finish fastener. Thicker casing, baseboard or molding assemblies may require a longer 18GA brad or a heavier finish-nail platform.
The correct drive depth should leave the brad properly seated without excessive countersinking or surface damage.
