For Through Bolt Anchor.
Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- European Technical Approval Option 1 for cracked and non-cracked concrete, strength classes C20/25 to C50/60, reinforced or unreinforced. Seismic category C1, fire resistance F120, reaction to fire class A1.
- Bolt and expansion sleeve in stainless steel 1.4404 (A4/316), nut A4-80, washers A4.
- Sizes M8 to M16, article codes 3700806 (M8 x 68) to 3701622 (M16 x 220). The m1tr-C comes as M8 x 75 (3710807).
- Installation for M12: 12mm drill, 100mm hole depth, 72mm effective anchorage depth, 60Nm torque, 150mm minimum concrete thickness. Torque M8 20Nm, M10 40Nm, M16 120Nm.
- Recommended resistance for one M12 at 72mm effective depth in C20/25 concrete, with no edge, spacing or splitting effects, safety factor 1.4 on load plus the ETA material factor: tension 9.52kN non-cracked, 5.71kN cracked; shear 15.06kN cracked or non-cracked.
- Characteristic and design resistances and the edge and spacing tables are for engineers. Loads must be reduced at minimum spacing, edge distance or member thickness.
- Hammer drilling only, clean the hole, set once only. Design to ETAG 001 Annex C with the full ETA-12/0375, checked by an engineer experienced in anchorage and concrete work.
Who it helps: Engineers and builders who need a stainless throughbolt for cracked or non-cracked concrete.
