Introduction

Cylindrical Dowel Pin is a precision-ground industrial alignment fastener used for accurate positioning and rigid fixation of mating mechanical components.

What Makes Our Ropes Better

High Dimensional Accuracy

Micron-level diameter tolerance control supports high-precision interference fits for repeatable part repositioning.

Durable Materials

High-grade GCr15 bearing steel with full-body quenching provides a hard structural core resistant to lateral shear and bending.

Smooth Surface Finish

Precision grinding achieves a consistent low-friction surface, facilitating smooth press-fit installation into standardized boreholes.

Smooth Alignment

The 15-degree lead-in taper ensures immediate, scratch-free centering during manual or high-speed automated assembly.

FAQ

Q: How do you ensure the pins stay locked under heavy vibration?

A: Our pins are ground with a slight positive tolerance, creating a permanent mechanical bond with the borehole that resists loosening even under cyclic shocks.

Q: Are these pins suitable for corrosive or high-temperature environments?

A: While standard bearing steel is oiled for protection, we offer specialized 304/316 Stainless Steel versions for chemical, food-grade, or outdoor applications.

Q: Can the pins be removed without damaging the expensive mold plates?

A: Yes. The high surface finish and controlled hardness prevent the pin from "seizing" in the hole, allowing for clean extraction and part replacement.

Q: Do you provide mill test certificates for material verification?

A: Absolutely. Every shipment is accompanied by a Material Test Report (MTR) detailing the chemical composition and hardness levels of that specific batch.
