The JCP Fixings Throughbolts (M12 x 100) are designed for professional contractors and DIY enthusiasts who require a heavy-duty fastening solution for structural applications in concrete and masonry. These bolts provide exceptional load-bearing capacity and a secure hold, making them ideal for mounting heavy fixtures; however, they require precise drilling to ensure the expansion mechanism functions correctly within the base material.

These are primarily designed for concrete and solid masonry; they may not provide sufficient holding power in lightweight or aerated brick.
You should use a 12mm masonry drill bit to ensure the correct clearance for the M12 bolt.
While the BZP finish offers some corrosion resistance, they are best suited for dry, indoor, or sheltered environments.
The bolt has a total length of 100mm.
No, throughbolts are designed for permanent installation and the expansion mechanism is often damaged upon removal.
The drill hole may be too wide or the masonry is too soft; ensure you are using the correct drill bit size for an M12 bolt.
Check that the bolt has been inserted deep enough so that the expansion clip is fully inside the masonry substrate, not the fixture.
To install, mark your drill position accurately and use a high-quality masonry drill bit matching the M12 bolt diameter (typically 12mm). Drill to a depth slightly deeper than the bolt length to allow for debris clearance. Insert the bolt through the fixture and into the hole; use a hammer to tap it until the washer and nut are flush against the fixture surface. Tighten the nut with a torque wrench to the manufacturer's recommended specification to initiate the expansion. Once installed, the BZP finish should be inspected periodically in damp environments to ensure no surface oxidation has occurred.
