Dowel Pins, Spring Pins, Stepped Pins（Shape：Spring Pins）

It is used as a positioning part. Some brands call it a dowel pin or straight pin, but there is no difference in the standards.
Standards are stipulated in JIS, and products designed according to both the new and old JIS standards are available. MISUMI offers products of both standards, so note the difference in tolerance.
Besides the dowel pin, MISUMI offers abundant shapes such as spring pin and stepped pin, as well as sizes from 0.1 to 30 mm and length from 2 to 200 mm. [Materials] > Stainless steel, iron (steel), resin
[Nominal Diameter] > 0.1 to 30 mm

Spring Pin (for General Purposes)【1-1,000 Pieces Per Package】

OCHIAI

[Features]
· A thin sheet wound into a cylindrical form and slit down the middle. By inserting (press-fitting) into a small hole with a diameter slightly smaller than the outer diameter of the pin, the internal pressure acting on the hole (the force of the pin trying to expand) prevents the pin from coming out.
· Uses a hollow pin rather than a solid one, allowing for a reduction in weight.
· Used for positioning, preventing rotations, retaining, etc.
· Used for simple fastening, positioning, etc.
· The gripping force prevents it from coming out of the corresponding piece.
· Use a double pin if you want to increase the shear load. (The load is the sum of the shear load of both the inner and outer pins)
