Where can I buy the BoxBolt?
All sizes of the BoxBolt are stock items and are available through our distribution network. For information on your closest distributor please contact our sales office on +44 (0)118 931 1022.
Can I re-use the BoxBolt?
No, however it can be removed and the hole in the steel used again with another BoxBolt. Some blind bolt type fastening systems alter the properties and shape of the steel, even when the BoxBolt is removed the hole in the steel remains in good condition.
Can the BoxBolt be removed?
Yes, quite easily. If you remove the core bolt the cone will fall away and the body section can be prized out of the hole. Typically you would have to use a screw driver or a crowbar to lever under the collar section.
Can the BoxBolt be used in any shape of SHS?
The BoxBolt can be used with rectangular, square, circular and oval shaped sections
Can the BoxBolt be used with slotted holes?
Yes as long as the slotted hole is only in the outer material and a standard clearance hole is used on the box section. If there is any shear load this needs to be perpendicular to the direction of the slot.
Can the BoxBolt be used in concrete?
No, the BoxBolt is intended only to be used where there is a cavity. As the cone is pulled up and into the body of the BoxBolt the fins require room to expand. If used in concrete the fins would not expand properly and the BoxBolt would not work as intended.
What is the finish on the BoxBolt?
The mild steel BoxBolt has two different finish options, zinc plated or hot dip galvanized. Also they are available in Stainless Steel Grade 1.4401 (316). When ordering please specify which finish you require.
