How to Fit a Blind Bolt

If you’re looking for a fastener you’re looking for something which needs very little maintenance and remains fixed for a long period. Find a fastener like this and you can work on projects quickly and efficiently, and that’s why blind bolts – which offer this kind of quality – have become so popular so quickly.

There is a correct method when it comes to fitting blind bolts, however, and it isn’t simply a case of twisting the bolt into a hole. To do the job properly you have to bear in mind factors such as the size of the hole, the angle, the length of the joint and the tools you’re going to need. Get all of this right and you can be certain the bolt won’t fail in the long term.

  1. The Hole Size

    Two important factors depend upon the size of the hole you drill. These are the length of the blind bolt itself and the length of the grip. Both of these factors – which aren’t the same thing – have a bearing on the solidity of the final joint, because a bolt which is either too long or too short could work loose over time. Generally, your supplier will provide a guide which can be used to judge the right length of bolt, and you can also invest in grip gauges to do the job. Finally, a meter will enable you to drill the hole and check which size of bolt will be suitable.

  2. The Best Type of Blind Bolt

    The sheer range of blind bolts which are on offer can be a little daunting at first glance. Having lots of choice is clearly a benefit, but it also means you have to take the time to make sure you choose correctly for the job in hand. The choices available online or in stores range from heavy-duty bolts to hollow wall bolts, so it’s vital to make the right choice before purchasing, matching the bolt you buy to the project you’re working on.

    An M8 diameter bolt, for example, will have a tension of 9.8pt and a shear capacity of 14.6ps, while for an M30 diameter bolt these figures will be 174.5pt and 224.0ps respectively. What this means is that a job which involves high levels of pressure is one which calls for an M30 bolt.

  3. Proper Equipment

    Although it’s possible to fit a blind bolt using just a screwdriver it isn’t recommended. A blind bolt fitted in this manner, no matter how much effort you put in, won’t create a joint which is flush, and this reduces the shear and tensile strength of the bolt.

    For this reason, it’s vital to use power and hydraulic tools which can push the bolt into place quickly and simply. Using tools like this will guarantee maximum strength and efficiency with the added bonus of providing a professional finish with nothing hanging out or coming away from the seal. Anyone utilizing hand tools should make sure that they are able to apply sufficient power.

  4. When to Remove a Bolt

    If the seal created by the bolt isn’t flush then you should remove it and start the process of fitting again, ensuring a correct position. Sometimes it may be sufficient to simply loosen the bolt and push it deeper into the initial hole, creating a tighter grip. If this doesn’t work then it could be that you haven’t chosen the correct fastener, as this will impair the installation process.

    If chosen and fitted correctly, Blind Bolts represent an effective and affordable solution.
