China Grooved Pin Manufacturer, Supplier, Factory

Grooved pins are engineered for secure, permanent fastening in a wide range of applications, offering superior holding power compared to standard dowel pins. Their unique design allows for reliable performance in assemblies where vibration and shock loads are a concern. For applications requiring a different fastening mechanism, you might also consider other types of pins such as a Cotter Pin for securing bolts and nuts, a simple Round Pin for basic alignment, a Taper Pin for precise positioning in tapered holes, or a Pin Shaft for acting as a central pivot or axle in mechanical systems. The primary advantage of the grooved pin is its ability to distribute stress evenly, preventing loosening and ensuring a long-lasting connection.

The design of a Grooved Pin features longitudinal grooves along its shank, which collapse slightly upon insertion into a drilled hole. This creates a tight, press-fit interface that resists rotation and axial movement. The specific parameters and material properties of the Grooved Pin are critical for its performance. The following list and table detail the key attributes you should consider when specifying this component.

• Material: Typically made from case-hardened steel for high strength and wear resistance. Stainless steel and other alloys are available for corrosive environments.
• Groove Configuration: Three longitudinal grooves are standard, evenly spaced around the circumference of the pin.
• Hardness: Surface hardness is crucial for durability. Standard pins are heat-treated to achieve a high surface hardness while maintaining a tough core.
• Chamfered Ends: Both ends are chamfered to facilitate easy insertion into the mating hole.
• Standards: Manufactured to comply with international standards such as ISO 8734 and DIN 1481, ensuring consistent quality and dimensional accuracy.
