Types of Trailer Pins
Solid pin with a smooth surface; available in ASME B18.8.2, DIN, and mil-spec specifications. Ideal for precision alignment and connections with basic requirements.
Solid pin with a small flat surface to allow for gas and liquid to vent through the mating hole and chamfered ends to ease installation. Internal threads provide an easy removal mechanism.
Solid pin with a grooved surface that compresses upon installation to create a self-locking tension. Ideal for applications like pivots, levers, and locking devices.
Hollow rolled pin with chamfered end to ease installation. Hollow center makes it ideal for applications that require additional fasteners (like a bolt).
Solid pin with an internally threaded hole on one end to allow a slide hammer to remove the pin. Ideal for blind applications or situations where the pin needs to be removed from the same end as it was installed.

Diameter: Ranges from 1/16 (0.0625 inches) to 1 (1.000 inches) for inch/mil-spec sizes, and M1 (1mm) to M20 (20mm) for metric sizes.
Length: Ranges from 1/8 (0.125 inches) to 4-1/2 (4.5 inches) for inch/imperial lengths, and 3MM to 140MM for metric lengths.
Tolerance: Typically ±0.0001 inches for diameter and ±0.010 inches for length. -0/+0.0002 nominal diameter tolerance for MS16555 parts. ±0 / ±.0002 tolerance over/under nominal diameter for M21143 parts.
Surface Finish: Usually 32 microinch Ra.
Fit: Usually available in undersize/slip-fit or interference/press-fit.
Material: Commonly made from stainless steel (300, 400, 416, A1, A2, and A4 series), alloy steel (plain or phosphate finish), brass, and aluminum.
End Styles: Includes chamfered ends for easy insertion and radius ends to prevent distortion during installation.
Standards: ASME B18.8.2, MS16555, MS16556, MIL-P-21143, ISO 8734, DIN 7, and DIN 63251.
Precise Tolerances: These pins are hardened to precise dimensions, making them ideal for machinery, furniture, electronics, etc. that rely on critical alignment for peak performance.
Durability: Metal pins hold their shape and resist deformation, even after repeated use. They also possess good shear strength and do not chip easily.
Ease of Use: These fasteners are simple to install with an arbor press and easy to remove with pliers (if the end protrudes from the component) or a punch and a hammer (if the pin is flush with the mating surface). They also work as a stand-alone fastener, although some designs allow for a mating fastener to pass through the hollow center.
Lateral Movement Prevention: These pins add shear strength to their mating components, preventing lateral movement.
Application of Dowel Pins
Furniture
While typically concealed, dowel pins are often found inside of furniture. They are used to join two furniture parts together. The parts are designed with hollowed tube-like sections.
Shelves
Shelves often contain dowel pins. Like with furniture, shelves are often designed with hollowed tube-like sections to accommodate dowel pins.
Machines
In addition to furniture, dowel pins are often used for machines. Machines contain dowel pins for alignment purposes. Dowel pins are used to align the parts of a machine to ensure extreme precision and accuracy. Manufacturing machines require precision and accuracy.
