APPLICATION GUIDE · PRODUCT SELECTION
CONCRETE NAILS
HOW TO CHOOSE?
When selecting concrete nails, consider the substrate, installation method, tip design and technical dimensions together. This guide explains the differences between Grooved Concrete Nails, Concrete Nails and STEP Concrete Nails.
Selection is not based on nail length alone. Consider the component thickness, concrete properties and equipment being used. The technical tables list product options; they do not, by themselves, confirm suitability for every application.
1. CHOOSE YOUR INSTALLATION METHOD.
Grooved Concrete Nails, with their grooved shank, are a distinct nail type for concrete fastening. Concrete Nails and STEP Concrete Nails are supplied in 10-nail plastic strips for nailer use.
For nailer installation, compare the nail dimensions and collation format with the compatibility specifications in the tool manual. Belonging to the same product family does not mean every nail can be used with every nailer.
2. COMPARE THE THREE NAIL TYPES.
Grooved Concrete Nails: Developed for demanding concrete applications with a grooved shank. They can be used in C40 concrete; the grooves help improve grip and fixing strength within the concrete. The technical table lists the Diamond tip, diameter × length, and box and carton quantities. View Grooved Concrete Nail Dimensions →
Concrete Nails: Round-tip nails supplied in strips of 10 for nailer use. The product table lists six sizes, ranging from 2.7 × 20 mm to 2.9 × 40 mm. View Concrete Nail Dimensions →
STEP Concrete Nails: Developed for demanding concrete applications with special STEP tip geometry. They can be used in C40 concrete; the special tip supports controlled penetration and can help reduce the risk of concrete surface cracking. View STEP Concrete Nail Dimensions →
“Steel nail” is a broader term describing the material. When selecting nails for concrete, check that the product is intended for concrete use and review its technical specifications.
3. READ DIAMETER AND LENGTH TOGETHER.
For example, 2,7 × 27 mm means that the first number is the shank diameter and the second is the nail length. Two products of the same length may have different diameters or tip types. Use the product code to identify the correct size when ordering.
Do not assume that the longest nail is best without knowing the component thickness and substrate. Assess the required embedment depth and connection conditions according to the system’s technical information. This guide does not prescribe a fixed embedment depth or load-bearing capacity.
4. MATERIAL, TIP & EQUIPMENT COMPATIBILITY.
SAE / AISI 1065 identifies the steel grade, while 54–58 HRC identifies the hardness range on the Rockwell C scale. These describe the material and its hardness, not the load-bearing capacity of the connection on their own.
When using a gas-powered nailer, select a compatible fuel cell as well as suitable nails. Review the TNX100 and fuel cell information and confirm nailer, nail and fuel cell compatibility using the operating manual.
Concrete properties and surface condition can affect installation. Check the system’s technical instructions and assess a suitable trial fixing before the first application. Obtain project-specific technical approval for load-bearing or safety-critical connections.
5. BEFORE ORDERING CHECKLIST.
- Have you identified the substrate and the component to be fixed?
- Have you selected Grooved, Round or STEP nails?
- Have you confirmed the product code, diameter and length?
- For nailer use, have you checked model and collation compatibility?
- Have you checked the box and carton quantities in the technical table?
Strips, boxes and cartons are different units. Concrete Nails and STEP Concrete Nails contain 10 nails per strip, 1,000 per box, and 10 boxes / 10,000 nails per carton. Box and carton quantities for Grooved Concrete Nails vary by size.
