⚙️ M3–M10 White Knurled Thumb Screws – High‑Type Steps, Aluminum + A2 Stainless Steel

You’re in the middle of a machine build or a jig setup, and you need a fastener that you can turn by hand without searching for a wrench. These high‑type step knurled thumb screws combine a white anodized aluminum head with a 304 stainless steel (A2) threaded rod. The stepped, flat knurled head gives you an excellent finger grip, and the white finish looks clean on any equipment. Available in thread diameters from M3 all the way up to M10, and thread lengths ranging from 6mm to 135mm. Use them on camera rigs, 3D printers, industrial panels, or any spot where you want tool‑free adjustment with a professional appearance.

✨ Why These High‑Type Steps Knurled Thumb Screws Stand Out

  • Two high‑quality materials – Aluminum alloy head (anodized white) for lightweight grip + A2 (304) stainless steel threaded rod for rust resistance and strength.
  • Tool‑free knurled grip – The flat knurled head with step design (high type) gives you maximum finger traction, even with gloves on.
  • Massive size range – M3, M4, M5, M6, M8, M10 diameters. Thread lengths from 6mm up to 135mm. Head dimensions available in 12x12, 12x20, 16x20, and 20x20 (diameter x thickness).
  • Corrosion resistant & durable – The anodized white head resists scratches and oxidation; 304 stainless steel won’t rust in humid or outdoor environments.
  • Made to GB standard – Consistent metric threads for reliable engagement with standard nuts and tapped holes.
  • Versatile applications – Works perfectly for machinery assembly, jigs, fixtures, camera brackets, electronics enclosures, and DIY projects.

❔ Frequently Asked Questions

Are these fully stainless steel or just the threaded part?

The knurled head is white anodized aluminum – lightweight and comfortable to grip. The threaded rod is A2 (304) stainless steel. This hybrid design gives you the best of both: a non‑rust, strong thread and a head that won’t weigh down your equipment.

What does “high type steps knurled” mean?

It means the knurled head has a stepped profile (taller than a flat disc) with vertical knurling on the side. This gives you more surface area for your fingers and a better mechanical advantage when hand‑tightening compared to low‑profile thumb screws.

Do you offer other colors besides white?

This specific listing is for white anodized heads. However, we stock the same high‑type step thumb screws in many other anodized colors (black, red, blue, gold, etc.). Please check our store or contact us with your color preference.

I need a thread length not listed here – can you make it?

Yes. Our catalog includes many lengths beyond what’s shown in the dropdown. For M3 to M10, we can supply thread lengths from 6mm up to 135mm in 1mm increments. Just message us with the exact diameter, length, and head size you need, and we’ll confirm availability and pricing.

Will these work outdoors or in marine environments?

The A2 (304) stainless steel rod offers good corrosion resistance for most outdoor applications, including coastal areas with occasional moisture. For continuous saltwater exposure, we recommend upgrading to A4 (316) stainless – contact us for custom orders.

What’s the tolerance on thread diameter and length?

These are manufactured to GB standard tolerances (typically 6g for external threads). That means M3–M10 threads will fit standard metric nuts without binding. Length tolerance is generally ±0.5mm for shorter lengths and ±1mm for longer ones. If you need tighter precision, let us know before ordering.
