✨Automatic Sorting Machines for Nuts, Screws and Bolts: How to Choose the Right One✨
Choosing an automatic sorting machine for nuts, screws and bolts is not only about speed.
The most important factor is the feeding method that suits the part shape. If the part is not stable, the camera cannot capture it accurately.
This guide explains how to choose.
■ 4 things to know before choosing
- Part shape and size: can it stand on its own, does it have a head, how long is it, what is the diameter?
- Defects to detect: e.g. damaged threads, chipped heads, wrong dimensions or length, burrs, mixed part numbers. This decides the number of cameras and angles.
- Required speed: how many parts per day, to compare the cost with manual inspection.
- Invisible defects?: hardness or wrong material require eddy current testing.
■ Machine selection by part type
| Part characteristics | Examples | Recommended machine | Approx. speed |
|---|---|---|---|
| Stands on its own, flat base | Nuts, bushings, rivets, washers, O-rings | Glass table (VIZION / UAZNC) | 300–800 parts/min |
| Has a head, hangs by the neck | Screws, bolts | Index type (VIZION / UAZNC) | Up to about 300 parts/min |
| Cannot stand, long or unstable | Long parts | VIZION FERRIES1 | Depends on part |
| Shafts, pins | Motor shafts, pins | DECSYS shaft circumference & ends inspection | Depends on part |
| Small screws in high volume | M3–M5 screws | Special high-speed system | Up to 2,000 parts/min |

■ Don’t forget feeding and packing
Sorting machines work with parts feeders, and counting or automatic packing can be added, reducing labour in both inspection and packing.
