M20, Throughbolts, A2/304 Stainless Steel, Heavy Duty Masonry, Concrete Anchor

Fixaball sells all lengths of M20 though/ rag bolts, in A2/304 Stainless Steel.

Stainless Steel Grade A2/304 Throughbolt Masonry Anchor
Throughbolt, expansion anchors are used for fixing materials to non-cracked concrete/ masonry (brick/ blocks), and non-porous stone. The Stainless Steel Throughbolt is grade A2/304. 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.

Throughbolt, expansion anchors are used for fixing materials to non-cracked concrete/ masonry (brick/ blocks), and non-porous stone.

A2/304 Stainless Steel

A2 Grade Steel is also known as 304 and so, both are included in the description. This is a standard stainless steel that can resist weathering and chemical attack. It's application is used where the fixing will be prone to constant water, air and chemical exposure (eg. salt). A2/304 has a similar tensile strength to 8.8 high tensile steel.

 

Advantages

  • 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.

 

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.

Installation and Advice

  • Before installation, check the concrete’s strength/ grade, closeness to the edge etc. in order to make sure its class/ standard is suitable. 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.
