Wing Nuts
Wing nuts forged or cast for hand tightening, in steel, stainless and zinc.
Wing nuts for joints that get opened by hand, where a spanner would be a nuisance. The wings are sized for grip rather than for torque, so they are for clamping, not for structural joints.

What drives the price of this part
Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.
- Part size
- Thread range at M4–M16 metric decides which machine the part lands on and how many setups it needs. Size is the driver buyers most often leave out of a first enquiry, and it is the one that changes the quote fastest.
- Order size
- Minimum order is 1000 pieces, where setup and tooling are amortised across the batch and per-part cost settles around cycle time and material. Below that quantity the same part costs more per piece, not less.
- Certification and paperwork
- ISO 9001:2015. On a certified family the inspection and documentation work is part of the price: first article inspection, material traceability and the dimensional report are produced per order, not per sample.

How these parts are inspected
Matched to the callouts above and the instruments actually on the floor.
- Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
- Dimensional report against the drawing, with a 100% check on critical features rather than a sample
- Certificate of conformance and the mill certificate with every shipment
- Thread gauges over the full thread range on the drawing
The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.
Questions buyers ask
- Wing nuts for a vibrating machine?
- Only with a locking element, because they loosen easily. For vibration, use a nylon-insert wing nut or pair it with a wedge-locking washer.
