Workshop Practice in Fitting and Assembly
In fitting practice, students bolt a Bench Vice to a Work Bench or assemble a bolted bracket. They hold the bolt head with one spanner and turn the nut with another, so the bolt does not spin in its hole.
On machine and automobile jobs they take off and refit covers and flanges, tightening the bolts a little at a time in a cross pattern. The final tightness is checked with a Digital Torque Wrench. Teachers use the set to show why a ring, which goes right round a nut, slips less and rounds off fewer corners than an open jaw.
Frequently Asked Questions
Why use a ring spanner instead of an open-ended one?
A ring closes round the whole nut, so the load is shared by all its corners and the spanner is far less likely to slip. An open-ended spanner is quicker to slide on but grips only two flats.
What does deep offset mean?
The rings sit well below the line of the shank. Your hand stays clear of the surface, so you can reach a nut sunk in a recess or next to a raised face without scraping your knuckles.
Which sizes are in the set?
Eight spanners: 6 x 7, 8 x 9, 10 x 11, 12 x 13, 14 x 15, 16 x 17, 18 x 19 and 20 x 22 mm. Each figure is the width across the flats of the nut or bolt head that the ring fits.
How do I avoid damaging nuts and bolts?
Use the exact size and seat the ring fully on the nut. Pull the spanner towards you rather than pushing it, so your hand does not hit the work if it slips. Never lengthen the handle with a pipe or strike the spanner with a hammer.
