For cutting things like rusted bolts and nails protruding from a surface, it is best to use a pair of special angled-head bolt cutters which are designed to keep the jaws flush to the surface. Compact-size bolt cutters should be quite adequate for the job.
Step 1 – Assess material
As with cutting other metals, it is important to assess the material you are going to tackle with your bolt cutters, to check that it is not hardened. Most nails, bolts and screws, however, should not be.
Step 2 – Position material
Manoeuvre the cutters to the deepest possible position on the shank of the bolt, screw or nail for the strongest cut. If a bolt is fastened too tightly for you to access the shank, you will have to cut the head instead – aim to cut as close to the bottom as possible to keep your tool from slipping.
Step 3 – Apply force
Press handles together smartly and the upper part of the nail or bolt should easily snap off cleanly.
