Precision Threaded Locating Pins

Applications & Functions

Our precision threaded locating pins are heavy-duty alignment and positioning components engineered for exact parts registration and fixture setup. Designed with a threaded shank, these pins ensure secure and vibration-resistant fastening in pre-tapped holes, preventing axial movement and maintaining tighter alignment tolerances.

They are widely used in demanding industrial applications:

• Automotive & Aerospace Jig Fixtures: Ensures ultra-precise spatial alignment of body panels and components during welding, assembly, and CMM inspection.

• CNC Milling & Machining Fixtures: Acts as a reliable datum point for quick-change workholding plates, allowing rapid workpiece loading with high repeatability.

• Stamping & Mold Tooling: Guarantees precise registration and alignment of upper and lower molds under extreme mechanical pressures.

• Automation Equipment: Serves as a mechanical guide and physical stop for robotic grippers and linear motion slides.

Outstanding Product Features

• High-Precision Dimensional Tolerances: CNC manufactured to ultra-tight tolerances (up to $\pm 0.005\text{ mm}$), ensuring an exact slide or slip fit without unwanted play.

• Superior Thread Engagement: CNC-cut threads provide a smooth, secure fit into tapped base plates, ensuring the pin stays perfectly perpendicular to the mounting surface.

• Tough Material & Hardness Options: Available in premium carbon steel (induction-hardened) or corrosion-resistant stainless steel (AISI 304/316) to prevent wear, bending, or deformation.

• Chamfered Lead-in Tip: The precision chamfered/tapered nose design allows for smooth, effortless part insertion and guides mating components seamlessly into position.

• Optimized Surface Finish: Fine-ground locating diameters reduce friction and prevent galling, extending the service life of both the pins and the workpieces.
