Products / Turned parts and legs
Fluted, spiral and smooth dowel pins for furniture assembly, long dowel rods and craft dowels, cut to diameter and length and packed in bulk by count.
A dowel looks like the simplest wood product there is, but a dowel pin is a precision part. It has to slide into a drilled hole with light pressure, hold glue along its full length and swell just enough to lock the joint. A pin that is 0.1 mm too fat splits the part or will not go in. A pin that is too thin or too wet gives a loose joint that fails in the field. Dowel factories make pins and rods on dedicated rounding machines, then groove, cut, chamfer and dry them before packing.
Most of the cost is in volume and handling, not in the wood. Furniture brands and kit makers buy dowel pins by the hundred thousand, so the quote depends on diameter, length, groove type, tolerance and how the pins are packed. Long dowel rods and craft dowels are priced more on length, straightness and surface quality. Tell the factory what the dowel goes into, the hole size and the glue. It can then match the fit.
Name the type on the RFQ. Factories that make one type well do not always make the others.
| Type | What it is | Fits |
|---|---|---|
| Fluted dowel pins | Short pins with straight grooves along the length, often pressed into the surface rather than cut. Ends are chamfered on both sides. | Glued furniture joints and cabinet boxes. The grooves let air and extra glue escape from the hole. |
| Spiral grooved pins | Pins with a spiral groove that spreads glue around the pin as it is driven in. | Machine insertion lines and joints where glue coverage matters more than speed. |
| Smooth dowel pins | Plain round pins with chamfered or rounded ends, no grooves. | Alignment pins, knock-down kits that ship with loose pins and joints assembled without glue. |
| Dowel rods | Long smooth rods, often 900 to 1220 mm long, from a few mm up to about 50 mm in diameter, typical. | Rails, hanging rods, spindles, displays and parts the buyer cuts to length. |
| Craft dowels | Short or long smooth dowels in small diameters, sanded clean and packed in counted bundles. | Craft retail, hobby kits, signs and model building. |
Starting points used across the trade. Your drawing sets the real values, and each factory confirms what it can hold on the quote.
| Spec | Typical value | Note |
|---|---|---|
| Pin diameter | 6, 8 and 10 mm most common, also 1/4, 5/16 and 3/8 in for US buyers, typical | Give the drill size of the hole the pin goes into, not only the pin size. |
| Pin length | 30, 35 and 40 mm for 8 mm pins, typical | Length is usually about four to five times the diameter. |
| Diameter tolerance | About +0 / -0.1 mm on pins, typical | State the tolerance and how it is measured: caliper or go / no-go ring gauge. |
| Length tolerance | About ±0.3 to ±0.5 mm on pins, typical | Tighter if pins are fed by an automatic insertion machine. |
| Rod straightness | About 1 to 3 mm bow over 1 m, typical | Long thin rods bow more. State the limit if rods are used uncut. |
| Moisture content | About 6 to 8 percent for pins, typical | Dowels are dried below the parts so they swell slightly in the glue and lock the joint. |
| Ends | Chamfered both ends, about 1 mm, typical | Say if you need rounded ends or one end chamfered only. |
Typical values, not a guarantee. Confirm every value that matters to you on the quote and the approved sample.
The usual process chain, from dried lumber or panels to packed goods. Ask which steps happen in-house and which go out to another plant.
Dowel pins are sold by count, often in bags of 1,000 or more per carton, with minimums set per size. Rods are sold by piece or by bundle. A first order often covers several sizes in one container with other wood parts.
Buy dowel pins in volume for glued case and frame joints. They care about fit in the hole, moisture and steady supply.
Pack loose pins with flat pack furniture and toys. They need counted packs and pins that fit holes drilled at another plant.
Buy rods and craft dowels in retail packs with barcodes. Surface, straightness and label artwork matter most.
With these points stated, every matched factory quotes the same product.
Approve one sample in writing and keep it as the reference for every shipment.

Metric 8 mm pins about 30 to 40 mm long are the most common in furniture and cabinets, with 6 mm and 10 mm pins for thinner and heavier parts. US buyers also order 1/4, 5/16 and 3/8 in pins. Match the pin to the hole you drill.
A pin dried to about 6 to 8 percent swells a little when it meets the water in the glue, which locks the joint. If the pin is as wet as the part, or wetter, the joint can loosen as it dries.
Both let air and extra glue escape from the hole. Fluted pins are the common choice for furniture lines. Spiral pins spread glue more evenly when driven by hand. Smooth pins suit glueless and alignment joints.
Yes. Most dowel plants can set up for a custom diameter or length, with a minimum quantity per size. Send the size, tolerance and yearly volume in the RFQ.
Usually in sealed plastic bags of a set count, packed in cartons. Retail and kit buyers can ask for smaller counted packs with barcodes. State the count per bag and per carton.
