🔘 M10 Knurled Thumb Screws – A2 Stainless Steel + Anodised Aluminium Hand Grip Knob Bolts (DIN 464)
You need a large, sturdy thumbscrew for heavy‑duty adjustments on machinery, jigs, or industrial equipment – something that’s comfortable to grip, completely rust‑proof, and built to last. These M10 knurled thumb screws combine a lightweight, knurled aluminium head with a robust A2 stainless steel threaded stud. The diamond knurling gives you a secure, non‑slip hold, even with oily hands, and the stainless steel thread resists corrosion in demanding environments. Fully threaded, with stud lengths measured under the head. Available in pack sizes of 1, 5, or 10 pieces. Perfect for machine clamps, tool‑less access panels, camera pedestals, and any application where a large‑format hand‑operated fastener is required.

❓ Frequently Asked Questions – M10 Knurled Thumb Screws
1. How do I measure the length of an M10 thumb screw?
The length is measured from the underside of the aluminium head (where the knurling meets the shaft) to the tip of the stainless steel thread. The head itself is NOT included. For example, an “M10 x 20mm” screw has a 20mm long threaded stud under the head. Select your required stud length from the dropdown.
2. Are these screws fully threaded? What about longer stud lengths?
Yes – all M10 screws in this range are fully threaded from under the head to the tip, ensuring maximum grip in tapped holes or when using a nut.
3. Is the aluminium head anodised? What colours are available?
The standard finish is natural silver (clear anodised). For custom colours (black, red, blue, etc.), please contact us – we can anodise to your specification for bulk orders.
4. Will the A2 stainless steel stud rust? Can I use these outdoors?
A2 stainless steel (304) offers excellent corrosion resistance for indoor and outdoor use. It will not rust under normal conditions. For continuous saltwater or harsh chemical environments, consider A4 (316) stainless – contact us for custom orders.
5. Do I need a nut or washer with these thumb screws?
If your equipment has a pre‑tapped M10 hole, no nut is needed. For plain holes, use a standard M10 metric nut (1.5mm pitch). A flat washer is optional for load distribution.
6. What is DIN 464? Why is it important?
DIN 464 is the German standard for knurled thumb screws with a round, high‑profile head. It specifies exact head dimensions, knurling patterns, and thread tolerances – ensuring consistent quality and interchangeability.
