Today, we will introduce you to the Dowel Pin. What is a Dowel Pin? If you have ever shopped at Ikea or assembled furniture on your own, then you are familiar with the peg shaped non-threaded wooden pins that are used to join parts together, aka as a Dowel Pin. For the purposes of manufacturing, Dowel Pins are solid, headless cylindrical shaped straight metal pins with a centerless ground finish. Typically hardened and manufactured to precise fractional diameters and lengths, Dowel Pins come in a variety of sizes, styles, designs and materials that cause confusion among buyers, engineers and end-users alike! Today, we will try simplify this confusing category of fasteners.

Today, we will introduce you to the Dowel Pin. What is a Dowel Pin? If you have ever shopped at Ikea or assembled furniture on your own, then you are familiar with the peg shaped non-threaded wooden pins that are used to join parts together, aka as a Dowel Pin. For the purposes of manufacturing, Dowel Pins are solid, headless cylindrical shaped straight metal pins with a centerless ground finish. Typically hardened and manufactured to precise fractional diameters and lengths, Dowel Pins come in a variety of sizes, styles, designs and materials that cause confusion among buyers, engineers and end-users alike!
Today, we will try simplify this confusing category of fasteners. Who uses Dowel Pins? Dowel Pins are used as a hinge, shaft or pivot to locate or hold parts together within a precision assembly or a fixture. They are broadly used across various applications in many industries, including: aerospace, electrical motors, hydraulic equipment, instrumentation, tooling and fixtures, machinery, military and many more.
Dowel Pins are popular within assemblies since they can withstand frequent insertion and removal without distortion. And production favors pins since they require no extra fastening hardware for insertion, no secondary operations and no mating parts. All this adds up to speedier production, which makes everyone in the food chain happy! What do I need to consider when selecting Dowel Pins? Although Dowel Pins are offered in a multitude of materials and styles, when it comes to the main commercial and Mil-spec offerings, there are a few main issues to consider.
Standard, Oversized or Undersized? Standard series Dowel Pins are used for initial applications. They have a basic diameter 0. Oversized series Dowel Pins are usually used to fit into worn holes and are generally used in the aftermarket for repairs. Undersized series Dowel Pins are used for inconsistent holes.
They have a basic diameter Chamfer or radius on the end? Standard alloy pins will have a radius on one end and a chamfer on the other end. However, stainless steel Dowel Pins are often manufactured with a chamfer on both ends. Commercial or Military? If you or your customer needs domestically made, DFARs pins to the most exacting standards, then military may be the right pin for you!
Alloy or stainless? And which stainless for that matter? Alloy Steel is the strongest pin available and is hardened. It can be finished with Black Oxide to provide greater rust resistance than plain alloy. Type Stainless steel is the strongest standard stainless steel offering, and is the material used for MS and MS series. Type Stainless Steel is the most corrosion resistant stainless available and does not correlate to a Mil-spec part. Are there other factors to consider?
Dowel Pins often show up under their Mil-spec numbers, which can be crossed to commercial equivalents. Some common Mil-spec series for Dowel Pins include Mil-P Stainless , MS standard series offered in both alloy and Stainless Steel and MS oversized series offered in both alloy and stainless steel.
For commercial pins, be mindful to specify the material and size tolerance that you need. Unless noted, Dowel Pins are precision ground, hardened and heat treated to meet the proper Rockwell hardness. And remember, no hammers! When installing Dowel Pins, never drive the pin into the hole with force, always press it in for best results. Brand names and generic equivalents. Custom made parts per print in non-standard and exotic materials and finishes.
Staff turnover, overseas competition and third party vendor issues can all threaten your service level and put pressure on your organization. But one of the biggest risks in is inflation. Rising material prices and inflationary forces are impacting costs at every level. What is a manufacturer to do? One of the most powerful ways to mitigate the risk of rising prices is through a proactive supply chain strategy that includes issuing Blanket Purchase Orders BPO. With a stable price for a fixed period of time, the BPO serves as a hedge against inflation.
