M12 Throughbolts A4 Stainless Steel Masonry Anchor ETA Option 7

M12, ETA Approved Option 7, Throughbolts, A4/ 316 Stainless Steel, Heavy Duty Masonry, Concrete Anchor Fixaball sells all lengths of M12 though/ rag bolts, in A4/ 316 Stainless Steel. Stainless Steel Grade A4/ 316 Throughbolt Masonry AnchorThroughbolt, expansion anchors are used for fixing materials to non-cracked concrete/ masonry (brick/ blocks), and non-porous stone. The Stainless Steel Throughbolt is grade A4/316. It is the ultimate "through fixing" with the hole diameter as the bolt diameter. It is ideal for bolting in place awkward fixtures without the need for marking out, removal and repositioning. It is a torque controlled anchor suitable for use in concrete over C20/25 strength. A4/ 316 Stainless Steel A4 Grade Steel is also known as 316 and so, both are included in the description. This is the marine grade, stainless steel that can resist heavy weathering and chemical attack. It's application is used where the fixing will be prone to constant water, air and chemical exposure (eg. salt). A4/ 316 has a similar tensile strength to 8.8 high tensile steel. Advantages of a Through Bolt High Performance, cost effective anchor for non-cracked substrates eg. concrete Suitable for reduced embedment to avoid contact with rebars/ reinforcement cages. Holes are the same diameter as the fixings so the fixing can be passed through the fixture after locating it in the right position. Cold formed body provides consistent dimensional accuracy and material stability High load-bearing capacity Undercut Anchors • Undercut anchors are ultra-reliable and an easy fix / easy solution for high loads in non-cracked and cracked concrete.• There is an extra guaranteed safety due to positive undercutting mechanism.• The anchors are produced from high strength durable materials that offer additional guarantees of safety.• They are suitable in applications where there is a need to reduce the edge distances and anchor spacing in the concrete. Option 7 ETA Approved The many benefits associated with undercut anchors mean that their use is not just restricted to Option 1 (Stress/ Load) areas of application. Many Option 7 areas of application still have requirements for ultra-high loads, close concrete edge distances and close anchor spacings. Option 7 being the ETA designation for the consideration of concrete which is not acting in tension and so is non-cracked. Orders placed before 2pm are dispatched same day (Mon-Fri). Standard, Free Delivery is Royal Mail, 2nd Class (2-5 days, most likely 2 days). For a faster delivery time, select 1st class or courier at checkout.

Reliability of masonry anchors starts with the substrate. The concrete base must be compact and crack free or a through bolt, expansion anchor will fail. Installation temperature range for base material: -5 / + 40 ºC (80 ºC for a short period of time). Minimum installation depth values must always be respected: for anchors’ depth, for anchor-to-anchor distances and for anchor-to-edge distances. Drilling must be performed by respecting the specified minimum depth and diameter, perpendicular to the base material’s surface. The holes on the material to be fixed may be used as templates. When drilling near any reinforcement areas, special care must be taken to avoid damaging them. If drilling is aborted because a reinforcement area has been encountered, it is advisable to drill a new hole at a minimum distance of at least twice the aborted drill hole diameter. This advisable distance may be reduced, as long as the aborted hole is previously filled up with high-resistant mortar. It is necessary to clean the holes thoroughly free of dust and debris with a suitably sized brush. When temperature is below 0ºC, make sure water does not seep into the hole, as this fact could cause subsequent cracks on the concrete, due to ice pressure. Introduce the anchor through the material to be fixed into the hole up to the embedment depth, according to the values on the table. It is possible to use a hammer to ensure the required depth. Do not apply any intermediate layer between the material to be fixed and the washer, such as sealing products. Apply the specified torque with a torque wrench. In the case the holes on the material to be fixed have a bigger diameter than required, it is necessary to insert a thicker washer and of a bigger diameter. But please, note that this procedure does not ensure a correct distribution of shear loads amongst all the anchors of a same group, and this shear load is applied only to the anchors with a correct diameter on the material to be fixed.

Advantages of a Through Bolt

  • High Performance, cost effective anchor for non-cracked substrates eg. concrete
  • Suitable for reduced embedment to avoid contact with rebars/ reinforcement cages.
  • Holes are the same diameter as the fixings so the fixing can be passed through the fixture after locating it in the right position.
  • Cold formed body provides consistent dimensional accuracy and material stability
  • High load-bearing capacity

Undercut Anchors

• Undercut anchors are ultra-reliable and an easy fix / easy solution for high loads in non-cracked and cracked concrete.
• There is an extra guaranteed safety due to positive undercutting mechanism.
• The anchors are produced from high strength durable materials that offer additional guarantees of safety.
• They are suitable in applications where there is a need to reduce the edge distances and anchor spacing in the concrete.

Option 7 ETA Approved

The many benefits associated with undercut anchors mean that their use is not just restricted to Option 1 (Stress/ Load) areas of application. Many Option 7 areas of application still have requirements for ultra-high loads, close concrete edge distances and close anchor spacings. Option 7 being the ETA designation for the consideration of concrete which is not acting in tension and so is non-cracked.
