Box Bolt® Steel Cavity Fixings
Specially designed fixings for attaching to hollow section steelwork or where access is restricted to one side only. Read More +
These versatile fixings are perfect for attaching handrail baseplates to metal frame structures and are available in a variety of sizes and lengths to accommodate attachments into a wide range of steelwork. BoxBolt® complies with the DIN 18800 and Eurocode 3 design methods for bolted steel connections and is also a Lloyds Register type approved for use.
Once the hole is drilled and deburred you can install these fixings with just a couple of spanners, one to hold the outer collar and one to tighten the screw. For larger installations we would recommend using an impact driver to speed up the initial tightening process, however you should always finish off with a Torque wrench to ensure the fixings are not over or under tightened. The recommended tightening torque is as follows:
M8 Fixings 25Nm
M10 Fixings 45Nm
M12 Fixings 80Nm
M16 Fixings 190Nm
M20 Fixings 320Nm
Please note: Lead time for Box Bolts would be 2-3 working days
