Steel dowel pins are often used in precision engineering applications for accurate location and alignment. These dowels have chamfers at each end to enable insertion and to guide alignment. This type of dowel is also available in other metals and engineering grade polymers.Jun 29, 2020
What material are dowel pins made of?
One of the most common materials in which dowel pins are made is wood. Wooden dowel pins, as shown in the adjacent photo, are cylindrical pieces of solid wood. They are usually made of hardwood varieties, such as beech or oak, that are denser and stronger than their softwood counterparts.Sep 16, 2020

Are dowel pins hardened through?
Standards: In accordance with ASME B 18.8. 2, hardened ground machine dowel pins have a core hardness of RC 47-58 and a minimum case hardness of RC 60. ... Dowel Pins are made 0.0002" over a standard diameter and are fit into a reamed hole.
Can you machine dowel pins?
Dowel pins are machined to tight tolerances. The holes that they go into are reamed holes also with a tight tolerance. That is when the hole is a slightly smaller diameter than the dowel. So during assembly the dowel pin must be pressed with force into the hole.Dec 23, 2013
What steel is used for dowel pins?
Most metal dowel pins are made of steel. With that said, they aren't all made of the same type of steel. Some dowel pins are made of high-carbon steel, while others are made of stainless steel or even zinc-plated steel.Sep 16, 2020
Are dowel pins hardened?
Unless noted, Dowel Pins are precision ground, hardened and heat treated to meet the proper Rockwell hardness.Jun 18, 2014
What can I use instead of dowel pins?
Alternatives to steel dowel pins include roll pins (slotted or spiral), grooved pins and cotter pins.Jun 29, 2020
What tolerance are dowel pins?
The most common standard inch or imperial sized precision dowel pin is made to the ASME ANSI B18. 8.2 spec and has a diameter tolerance of -0.00 / +0.0002 and length tolerance of +/-0.010. For example, a ¼” (0.25) diameter standard dowel pin will have a diameter between 0.2500–0.2502″.May 16, 2017

How do I choose a dowel pin size?
Diameter: Ideally, the diameter of the dowel should be approximately 1/3 – and never more than 1/2 – of the thickness of the wood being joined. For example, if your product is 1” thick, you should be considering a dowel pin 3/8” in diameter. If your product is 1-1/4” thick, a 7/16” diameter would be more suitable.
