Vision inspection & sorting machines for nut manufacturers.
A nut with a half-formed thread looks perfect from the outside — until it reaches the assembly line. Visimaster machines check the thread inside every single nut, along with its faces and dimensions, and sort NG pieces out automatically.
Damage, Head Crack, Head Damage, ID Thread Damage, Cut Mark, Scratch Detection, Dent Detection, Thread Burr, Half Thread
Other checks: Thread Present/ Absent/ Pitch Variation

How fast can nuts be inspected?
The Glass Disc configuration for nuts is published at inspection speeds up to 300 PPM, with dimensional checks like Across Flat, Across Corner, Inner and Outer Diameter on every piece. The exact speed for your nut is confirmed in the feasibility report.
How do I check if my nuts can be inspected?
Courier 50–100 sample parts — including a few defective pieces — to our lab in Bhosari, Pune. Our engineers run them on the actual machine platform and you receive a feasibility report, typically within a week. The check is free. Prefer to start online? Upload a drawing or photo on the Ask AI page and get an engineering answer in minutes.
Will it work on your exact part?
Describe your part to Visi, our AI sales engineer — or courier 50–100 sample parts (including a few defective pieces) to our Bhosari lab for a free feasibility study.
