Practicals on Inch Fasteners
Machines built to inch standards use inch nuts, and a metric spanner of nearly the same size rounds them off. A common ITI task is to sort fasteners by size before dismantling. Students make a rough check on the inch scale of a Steel Rule, then confirm the size by trying the spanner, ring end first.
In assembly practice the open end runs nuts down a stud and the ring end gives the last turn. On nuts with a long thread, students can time the same job with the Straight Ratchet Ring Spanner Set, which turns the nut without being lifted off. Final tightness on a test joint is read with the Digital Torque Wrench.
Frequently Asked Questions
Why are both ends the same size?
So you can change ends without changing tools. The ring takes the heavy turning at the start and finish, and the open jaw is quicker in between. A double-ended open or ring spanner carries two different sizes instead.
How do I tell an inch nut from a metric one?
Try the nearest inch and metric spanners: the right one slides on with almost no play. A nut that takes the 1/2 in spanner snugly should not be turned with a 13 mm one, even though the two sizes are close.
Can I slip a pipe over the handle for extra force?
No. The handle length suits the spanner size, and the extra force can bend the spanner or strip the thread. For a stubborn nut, soak it with penetrating oil, keep the ring square on the nut and apply steady pressure.
Which set should I choose for metric machines?
Choose a metric set such as the Box End Spanner Set, which runs from 6 x 7 mm to 30 x 32 mm. This combination set is for inch nuts and bolts only.
