Fixaball M20 Throughbolts A2 Stainless Steel Heavy Duty Masonry Concrete Anchor

For masonry and concrete fixings, the Fixaball M20 throughbolt anchor is made from A2/304 stainless steel and suited to non-cracked concrete, masonry and non-porous stone. This torque-controlled expansion anchor uses a hole diameter that matches the bolt diameter, allowing the fixing to pass through the fixture once positioned.

It is suitable for concrete over C20/25 strength and can be used where the fixing is exposed to constant water, air and chemical contact, including salt. The cold formed body supports consistent dimensional accuracy and material stability.

Safety information

• Check the concrete strength, grade and edge distance before installation.
• Use only in compact, crack-free concrete base material.
• Minimum installation depth values must always be respected, including anchor depth, anchor-to-anchor distances and anchor-to-edge distances.
• Drill to the specified minimum depth and diameter, perpendicular to the base material surface.
• Take special care when drilling near reinforcement areas to avoid damage.
• Clean holes thoroughly to remove dust and debris before installation.
• When temperature is below 0ºC, ensure water does not seep into the hole.
• Do not apply any intermediate layer between the material to be fixed and the washer.
• Apply the specified torque with a torque wrench.
