KYA 15° Plastic Sheet Concrete Steel Coil Nails 2.5×18mm are #45 high-carbon steel fasteners designed for professional direct-fastening applications involving compatible concrete, steel and wood assemblies.
The featured nail has a 2.5 mm (0.098") shank diameter, 18 mm (0.71") length, 5.0 mm head diameter, screw shank, diamond point and electro-galvanized finish. It is collated in a 15° plastic sheet coil with 300 nails per coil.
The #45 high-carbon steel construction and compact 18 mm length make this specification suitable for applications where a hardened short concrete steel nail is required. Actual suitability depends on the base material, attached component, required penetration and approved fastening tool.

This 2.5×18mm concrete steel nail is made from #45 high-carbon steel. The material is used where higher hardness is required for driving into compatible hard substrates.
The current product specification references the #45 steel electro-galvanized version for applications involving penetration into steel up to 2 mm. Final performance depends on steel hardness, substrate thickness, fastening tool power and installation conditions.
The featured nail uses a diamond point. The pointed geometry concentrates the driving force at the nail tip during installation into compatible substrates.
Concrete strength, aggregate hardness, steel thickness, edge distance and tool driving energy can all affect penetration and fastening performance.

The 2.5×18mm model uses a screw shank. Its helical shank profile is designed to increase mechanical engagement after the nail has been driven into a suitable fastening assembly.
Holding performance varies with the receiving material, embedment depth, fastener geometry and installation conditions. Trial fastening should be carried out when the substrate or application changes.

The featured concrete steel nail has a 5.0 mm head diameter. Head size is an important part of both attachment performance and nailer compatibility because the magazine, feed system and driver must accommodate the complete fastener profile.

The nails are connected in a 15° plastic sheet coil for automatic feeding through a compatible nailer. The plastic carrier maintains nail alignment in the coil and separates as each fastener is driven.
Each coil contains 300 nails, providing a high-capacity format for repetitive fastening work. The exact plastic-sheet geometry must match the magazine and feed system of the fastening tool.
The featured 2.5×18mm concrete steel nail uses a diamond point. KYA's wider coil nail range includes additional point geometries for different fastening requirements.

This product specifically uses a screw shank. Smooth, screw and ring shank configurations are available across the wider KYA coil nail range. Shank type should be selected according to the substrate, fastening requirement and approved tool specification.

The featured concrete steel nail measures 2.5 mm in shank diameter and 18 mm in length. Additional plastic sheet coil nail dimensions are available within the wider KYA product range.

2.5×18mm compact specification: 2.5 mm shank diameter and 18 mm nail length for compatible direct-fastening applications.
#45 high-carbon steel: Hardened steel material intended for suitable concrete and steel fastening applications.
Screw shank: Helical shank profile designed for mechanical engagement after driving.
Diamond point: Concentrates driving force at the nail tip.
15° plastic sheet collation: Holds the nails in coil form for automatic feeding through compatible tools.
Electro-galvanized finish: Zinc-coated surface providing light corrosion resistance.
300 nails per coil: High-capacity coil configuration for repetitive fastening.
40 coils per carton: Standard listed carton packing for this specification.
The 2.5×18mm #45 steel coil nail is intended for professional direct-fastening work where the nail dimensions, tool and substrate are compatible.
Furring strip fastening to compatible concrete or masonry substrates.
Steel-to-wood fastening in suitable framing and assembly applications.
Concrete formwork for suitable temporary fixing applications.
Drywall track fastening involving compatible metal track and base materials.
Electrical and conduit attachments where clips or boxes are fastened using an approved direct-fastening system.
