Undoing seized nuts and bolts by adding additional leverage to spanners


Be the first to comment

What is the issue?
Seized fastenings are a common encounter whilst carrying out maintenance, overhaul or repair on a sea going vessel.

Why address this?
Seized fastenings cause enormous problems delay and damage to equipment. Having a range of loosening techniques to deploy will quickly overcome these problems and keep work moving along.

How to address this?
Extend and add leverage to a spanner by inserting a pipe over it, see figure 1.
The length of a ring spanners arm is specifically designed so that in normal use a bolt cannot be over tightened. You should not extend the spanners leverage to tighten bolts and equally you should be restrained with a spanner when using smaller diameter fittings or working softer materials such as brass. When using a leverage pipe watch closely to make certain the wrench or spanner is not slipping over the flats of the nuts. Always use in conjunction with penetration oils and freeing agents.
