About this size
At the upper end of the range, dowel pins are structural as much as locational: they carry shear between plates that bolts only clamp. Removal becomes a design consideration at this size, so a blind hole wants either a tapped extraction thread or a through hole to push against. Pins this size are also stiff enough that hole alignment between mating parts matters more than the pin tolerance does.
Ti-6Al-4V is specified where mass matters or where the pin sits against titanium structure and galvanic pairing is a concern. It is roughly half the density of stainless at comparable strength, and it is biocompatible, which is why it appears in implantable and hand-held surgical hardware. It is slow and abrasive to machine, which lengthens the cycle time — price it against the alternatives in the configurator rather than assuming, because the ranking here depends on what bar stock costs on the day and it is not always what you would expect.
Specified in millimetres, the diameter tolerance is computed as an ISO 286-1 IT band rather than a fixed figure, so it tightens as the diameter falls — a 2 mm pin at h7 is held far closer in absolute terms than an 8 mm one at the same grade. Grades h5 through h8 are offered in metric, all of them shaft tolerances that fall at or below the nominal diameter. Which grade a given assembly needs is the designer's call, and the configurator prices each of them so the choice can be made against real numbers.
Need a different length?
This page prices a 32.000 mm pin, but the length is not fixed. The same 8.000 mm diameter is turned to order at any length between 0.508 mm and 101.6 mm — enter the one you need and the price updates immediately.
That is usually the reason to have a pin made rather than bought. A standard pin comes in standard lengths, so an odd length means cutting one down, which leaves a raw end to re-finish and puts the length tolerance at the mercy of whatever did the cutting. A pin turned to length arrives finished on both ends and held to ±0.1 mm. More on that on the custom length dowel pins page.
