JCP Fixings Throughbolts ZYP - M8 X 130 - Box Of 50

These throughbolts are primarily used for securely fastening heavy items to solid concrete and masonry, such as structural components, machinery, or heavy-duty fixtures.

Yes, they can be used in solid brick walls, provided the brick is dense and sound. They are not suitable for hollow or crumbling bricks.

Typically, an M8 throughbolt requires a drill bit of the same diameter as the bolt's unexpanded shaft, which is usually around 8mm, but it's best to consult the specific product packaging or manufacturer's instructions for precise requirements.

The hole depth should be sufficient to allow for the full expansion of the throughbolt. Manufacturers usually specify a minimum embedment depth; consult the product's technical data or packaging for the recommended depth.

Yes, the ZYP coating offers corrosion resistance, making them suitable for many outdoor applications, especially when used with appropriate washers and nuts.

The ZYP coating provides enhanced corrosion resistance, offering better protection against environmental factors compared to standard zinc plating, thus extending the lifespan of the fixing.

Ensure the hole drilled is the correct diameter and depth for the M8 throughbolt. Verify that the substrate is solid and not hollow. Clean the hole completely before insertion.

Check if the hole diameter is correct and ensure it is free from debris. A slight chamfer on the bolt's entry edge might help if the hole is precisely sized.

Refer to the JCP Fixings technical data sheets for specific load ratings based on substrate type and bolt size. Ensure the application does not exceed these specified limits.
