Workshop Practice with Adjustable Spanners

In an ITI fitter or mechanic course, students assemble and strip a bolted job, such as a bracket on a test plate, held in a Bench Vice. The job uses nuts of several sizes, so the adjustable spanner is reset for each one. Students learn to close the jaw firmly on the flats before every pull.

Teachers then compare it with fixed spanners such as the Double Ended Spanner set, whose rings grip a nut all the way round. Students see why a fixed ring is chosen for a tight or rusted nut and the adjustable one for odd sizes. A Pipe Wrench is shown for round pipe, which has no flats for a spanner to grip.

Frequently Asked Questions

Which way should an adjustable spanner be turned?
Fit it so the fixed jaw takes the pulling force. If the moving jaw takes the load, it can spring open slightly and round off the corners of the nut. Close the jaw snugly on the flats before each pull.

Which length should I choose?
A longer spanner turns a nut with less effort and opens wider for bigger nuts. The 6 in size suits small nuts in tight spaces, and the 12 in size suits larger nuts and fittings with flats. Many workshops keep the 8 in and 10 in sizes for general work.

Can an adjustable spanner replace fixed spanners?
For odd sizes and occasional jobs, yes. For tight, rusted or repeated work, a fixed spanner of the right size grips better. It has no moving jaw, so it is less likely to slip.

Can a pipe be slipped over the handle for more force?
No. Extending the handle or striking it with a hammer can strain the jaw and the worm screw beyond what the tool is made for. Use a longer spanner or a ring spanner instead, and free a rusted nut with penetrating oil first.
