X-U Nail for fastening to concrete

Application recommendation

• Base material thickness: Concrete: hmin = 80 mm
• Fastened material thickness: Wood: t₁ = 15-57 mm
• Fastener positioning in base material: Edge distance: c ≥ 70 mm, Spacing: s ≥ 100 mm

Fastener shank length recommendation

Required nail shank length: Ls = HET + t₁ [mm]. In case flush fastenings are required: Ls = HET + t₁ – 5 [mm]. Recommendation: HET = 22 mm.

X-U Nail for fastening steel to steel

Application recommendation

• Fastened material properties: Fastened material thickness: t| ≤ 3 mm (not pre-drilled), 3 mm < t ≤ 6 mm (pre-drilled)
• Condition for fastened material thickness: 3 mm < t₁ ≤ 6 mm
• Base material properties and fastener positioning in base material: Base material thickness: t|| ≥ 6.0 mm, Edge distance: c ≥ 15 mm, Spacing: s ≥ 20 mm, Rolled shapes

Fastener shanks length recommendation

Ls = hET + t₁ [mm], HET = 12 ± 2 mm

Application limitation

For X-U 16 P8, X-U 16 P8TH, X-U 15 P8TH

Steel thickness, t₁₁ [mm]

Steel strength, Rm [N/mm²]

On higher steel grades, fastening with single nails (P8 or P8TH) may yield better results (e.g. less shear brakes) than fastening with collated nails (MX or MXSP) due to better nail guidance.

Performance data

Recommended resistance under tension and shear load

Tacking of steel sheets with X-U 15

Conditions

• Valid for steel sheet with minimum tensile strength ≥ 360 N/mm².
• For intermediate sheet thicknesses, use recommended load for next smaller thickness.
• In case of a design based on the characteristic resistance, recommended values have to be multiplied by two: NRK = Nrec · 2.0, VRK = Vrec · 2.0
• For X-U 16 S12: Base material thickness til,min = 8 mm for t₁ ≥ 1.50 mm, Base material thickness til,min = 6 mm for t₁ ≤ 1.25 mm
• Other fastened parts: clips, brackets, etc.
• Redundancy (multiple fastening) must be provided.
• Valid for predominantly static loading

Forces of constraint

When fastening large pieces of steel, the possibility of shear loadings from forces of constraint should be considered. Avoid exceeding Vrec for the fastener shank!

System recommendation

Cartridge recommendation for X-U 16 P8, X-U 16 P8 TH, X-U 16 MX

Cartridge recommendation for X-U 15 P8TH

X-U Nail for fastening wood to steel

Application recommendation

• Fastened material properties: Fastened material thickness: tj 15–57 mm
• Base material properties: Base material thickness: t|| ≥ 4.0 mm

Fastener shank length recommendation

For standard fastening: Ls = hET + t₁, HET ≥ 8 mm

For flush fastening: Ls = hET + t₁, HET ≥ 5 mm

Application limitation

For X-U 22 P8 to X-U 62 P8

Steel thickness, t₁₁ [mm]

Wood thickness, t₁ [mm]

On higher steel grades, fastening with single nails may yield better results (e.g. less shear brakes) than fastening with collated nails due to better nail guidance.

Performance data

Recommended resistance under tension and shear load

Conditions

• For safety-relevant fastenings sufficient redundancy of the entire system is required.
• In case soft material is fastened, its strength determines the loads.
• To limit penetration of nail and to increase pull-over load, use nails with washers.
• Observance of edge distance and fastener spacing in compliance with recognized standards EN 1995 (see approval).
• With respect to details of fastening wood, chipboard or OSB members to steel base material, it is refered to the German approval DIBt Z-14.4-517.

Procedures for building materials submission

This section outlines the procedures for submitting proprietary building products to the Buildings Department in Hong Kong. It clarifies that the Building Authority does not approve proprietary building products directly. Instead, authorized persons and registered structural engineers are responsible for supervising the selection and installation of these products, ensuring compliance with the Buildings Ordinance and manufacturers' specifications. Prior approval from the Buildings Department is not required for installation, but relevant information should be submitted with project plans.
