Dowel Pin Features
Dowel Pins are solid, headless, straight pins with a closely controlled diameter. One end is chamfered, with the other end radiused to form a crown. Dowel pins have a variety of uses, including as a plug gauge, hinge, or shaft. Precise tolerances of dowel pins make them excellent for achieving proper alignment of parts in high-speed assemblies, or as roller bearings in bus/truck wheel housings.Dowel Pin Materials and Sizes
Dowel pins are available in a variety of materials and inch and metric dimensions. They have tight tolerances and are used in industrial applications that require precise alignment. Options include:- Through-Hardened Alloy Pins: Ideal for high-shear and high-vibration environments; meets ANSI/DIN standards.
- Stainless Steel Pins (18-8, 316, 416): Great for corrosion resistance and non-magnetic applications. Available in A2 and A4 stainless for metric dowel pins.
- Oversized and Pull-Out Style Pins: For slip-fit, oversized, or worn holes. Available in multiple diameters and tolerance classes, including m6 and h8, in inch or metric sizes.
