Dowels - Import export

Our variety of lengths and diameters of dowel rods enables you to more easily create custom woodworking pieces for projects big and small. Our selection includes walnut, oak, cherry, birch dowels and more.

SPIROL’s GD100 Ground Hollow Dowels are designed to be direct replacements for Ground Solid Dowels manufactured per ISO 8734 when used in alignment applications. This innovative product is manufactured from strip steel, and then OD ground to achieve extremely tight diameter tolerances that enable critical alignment up to 20µm. The main advantage of the GD100 Ground Hollow Dowel is its ability to achieve the same alignment as the Ground Solid Dowel with a significant reduction in cost due to its hollow construction. In most scenarios, the Ground Hollow Dowel is approximately 50% lighter and at least 30% less expensive than the solid equivalent. If installation equipment is required, SPIROL also offers a standard comprehensive line of Installation Equipment from manual to fully automatic modules, with or without out fixturing, to support your assembly requirements.

SPIROL’s Dowel Bushings and Spring Dowels are designed to maintain alignment and are used to locate components with respect to each other. These roll-formed, hollow Alignment Dowels have lead-in chamfers that facilitate insertion into the holes of both mating components. The Dowel's flexibility enables absorption of wide hole tolerances and the staggered seam prevents interlocking. Dowel Bushings are designed with an inside diameter clearance that allows the passage of a bolt for fastening, thereby eliminating the need to drill an additional hole. They are also heat treated to isolate the bolt from shear loads.

The dimensions of the dowel pin comply with DIN 6325. Advantages: Ideal for fixture construction Dimensionally stable even at high temperatures Electrically insulating

SPIROL's KP300 Helical Knurled Pins have helical knurls that span the full length of the pin. The 30° helical knurls cause the pin to rotate during installation into the hole. Helical Knurled Pins offer higher insertion and retention than Straight Knurled Pins. However, KP300 Helical Knurled Pins are not typically recommended when the pin will be subjected to rotational forces as the helical knurl will cause the pin to either "unscrew" itself from the hole or further imbed itself into the hole. KP300 Helical Knurled Pins are available in metric diameters ranging from 2mm to 6mm and in inch diameters ranging from .078" (5/64) to .250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL's KP200 Straight Knurled Pins have straight knurls that span the full length of the pin. Straight Knurled Pins are commonly used in applications where the pin is subjected to rotational forces to transmit torque as well as to resist rotational movement of a mating component. KP200 Straight Knurled Pins are available in metric diameters ranging from 2.5mm to 6mm and in inch diameters ranging from .094" (3/32) to .250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL's DP100 Straight Pins have smooth outer diameters with no retention features such as knurls or barbs. When used as a press-fit pin, the DP100 Straight Pin is pressed into a hole sized slightly smaller than the diameter of the pin. SPIROL's DP100 Straight Pins are suitable for press fit in host materials that can withstand compression in the order of 0.05mm – 0.08mm (.002” – .003”). The actual recommended hole size for a press-fit depends on the actual host material. It is for this reason that SPIROL Engineering should be consulted for the recommended hole size when DP100 Straight Pins are intended to be press-fit into an assembly. Straight Pins are a great option for applications that do not require the tight tolerances of Machined Solid Pins or Ground Solid Dowels. SPIROL Series DP100 Straight Pin consists of metric diameters ranging from Ø2mm to Ø6mm and inch diameters ranging from Ø.078" (5/64) to Ø.250" (1/4).

Offered with or without a head, Straight Pins are distinguished by their uniformity. The chamfered ends are more consistent than tumbled edges—making installation with automatic assembly equipment more reliable. Straight Pins are retained by compressing the host, not the inflexible solid pin. They are suitable for use in plastics for press-fit applications limited to those cases where the host material can withstand compression in the order of 0.05mm – 0.08mm (.002” – .003”). Straight Pins are often used to replace Ground Dowels in applications that do not require the tight tolerances of a Ground Dowel.

The nominal diameter of the pin is the same as the receiving hole diameter. The recommended hole tolerance is ISO H12. Due to the chamfered end, the pins can be inserted easily into the hole with a hammer or using automatic placement. After insertion, the plus tolerance of the pins results in a vibration-proof seating. The pins can be easily removed using a mandrel and reused several times. The pins can transmit high shear forces and are resistant to shocks and impacts due to their spring properties. The values specified for the shear force only apply to spring steel.
