DIN 466 high, DIN 467 flat, through- and blind-bore knurled nuts turned from solid bar — in the threads and materials no catalog stocks. Fine pitches, M12+, brass, phosphor bronze, 316L and titanium.
Standard knurled thumb nuts are cheap and stocked everywhere — so the honest first question is whether you need a custom one at all. Here's the line we draw before quoting:
A standard DIN 466 or DIN 467 size in M3–M10, brass or 303 stainless, through bore. Accu, JW Winco, Fastenright and Elesa+Ganter stock these — order them there, faster and cheaper than made-to-order.
A fine, imperial or left-hand thread, a larger size (M12+), a blind bore so the stud doesn't poke through, phosphor bronze / 316L / titanium / PEEK, a special knurl or height, or a replacement for a worn nut with no size marking. Turning jobs.
Building a hand control? We machine matching thumb & knurled screws in the same knurl and material, so the nut and screw of a clamp or adjuster look and feel like a set.
| Type | How it works | When to choose it |
|---|---|---|
| High knurled (DIN 466) | Tall diamond-knurled body turned from bar for maximum finger grip | Higher hand-tightening torque; frequent adjustment |
| Flat knurled (DIN 467) | Low knurled body | Tight clearances, lighter loads, low profile |
| Blind-bore | Thread stops short of the top face | Exposed controls where a protruding stud is unsafe or ugly |
| Shouldered | A locating shoulder under the knurled body | The nut seats and locates against a face |
| Adjusting / large | Oversized knurled body for fine hand adjustment | Tensioners, stops and set-up nuts |
| Knurled nut + captive washer | Machined with a retained washer | Even clamping without a loose washer |
Every dimension floats: thread size and pitch, knurled diameter, height and bore depth are whatever the drawing says — matched with our thumb screws or measured from a worn nut the same way as any replacement fastener.
A knurled nut is turned by hand, so material sets the feel, grip, corrosion resistance and weight as much as the strength. Brass and phosphor bronze give a warm, positive grip and resist corrosion; 316L handles washdown; titanium and aluminum cut weight. Start from the job, then read the numbers:
| Material | Density | Why choose it for a knurled nut |
|---|---|---|
| Brass C360 | 8.5 g/cm³ | Warm feel, positive grip, decorative, conductive |
| Phosphor bronze | 8.8 g/cm³ | Corrosion resistance and wear for marine hand controls |
| Stainless 304 | 7.9 g/cm³ | General corrosion resistance, outdoor and food |
| Stainless 316L | 8.0 g/cm³ | Marine, washdown and chemical use |
| Aluminum 6061 | 2.70 g/cm³ | Light, anodizable in colors for coding controls |
| Titanium Gr5 | 4.43 g/cm³ | Light and strong for weight-critical assemblies |
| PEEK | 1.3 g/cm³ | Electrical insulation, chemical resistance, no marring |
Enter your nut's knurled diameter, thread bore and height to compare the exact weight and relative material cost of every option:
That's a blind-bore knurled nut: we machine the thread to a set depth so the top face stays closed and clean. In the knurl, height and material you want, with matching thumb screws if the panel needs them.
Phosphor bronze and fine threads are a routine turning job. We machine the knurled body and thread to your spec, corrosion-ready for salt exposure, one-off or in a set.
Send the old one. We measure the thread, knurled diameter and height and reproduce it from the sample — original or upgraded material — with spares in the run.
Matched hand hardware: thumb screws, set screws and coupling nuts can be machined in the same knurl, material and finish, so a clamp or adjuster arrives as one consistent, certified set.
Yes — the usual reason to machine them. We turn fine, imperial or left-hand threads, larger sizes and special knurls or heights to your exact dimensions.
DIN 466 is the tall knurled nut for the most grip and torque; DIN 467 is the flat, low-profile nut for tight clearances. We machine both, plus shouldered and blind-bore versions.
Yes — a closed top so the stud doesn't poke through, cleaner and safer on exposed hand controls. We machine the thread to a set depth in your head style and material.
Brass or phosphor bronze for feel and corrosion; 304/316L for washdown; aluminum or titanium to save weight; PEEK to insulate. Use the calculator on this page to compare weight and cost for your size.
One piece. No tooling charge — a single 316L knurled nut in an odd thread is a normal order. Unit price falls on batches.
The thread size and pitch, the nut height and knurled diameter, whether the bore is through or blind, the material or environment, and the quantity — or simply the old nut. A drawing helps but a dimensioned sketch or the sample is enough. Quote within 12 hours.
