M4 × 0.70 zinc-plated steel knurled thumb nut for tool-free adjustments on printer panels, brackets, jigs, and other hardware where a standard hex nut is awkward to reach.
Why use a knurled thumb nut
- Raised knurled head gives finger grip for repeat adjustments without a wrench.
- Semi-flanged collar spreads load better than a plain round thumb nut and helps cover oversized or irregular holes.
- Zinc-plated steel is a practical dry-environment choice when you want a tougher metal nut without paying stainless prices.
Specifications
- Thread: M4 × 0.70 mm metric coarse
- Head diameter: 12 mm
- Material: zinc-plated steel

Use it for
- Hand-tightened printer enclosure panels, brackets, spool holders, stops, and service-access hardware.
- Fixtures or printed parts that need repeated removal without loose tools.
- Same fastener family as the live M3 black zinc-plated thumb nut and M3 stainless thumb nut.
What it is not
- Not a lock nut; add threadlocker or a locking fastener if vibration resistance is required.
- Not stainless steel; choose stainless for wet, corrosive, or cosmetic applications.
- Not a screw or bolt — this is the mating nut for an M4 × 0.70 threaded fastener.
