Slotted Knurled Locating Pin
Products Description
Compared to smooth or simply knurled locating pins, the biggest advantage of slotted knurled locating pins lies in their unique "elasticity + interlocking" composite locking mechanism. The slot allows for slight radial contraction of the pin during pressing, compensating for minor hole diameter deviations and preventing substrate cracking or embedding difficulties. The knurling creates multi-point mechanical interlocking during material displacement, significantly enhancing torsional and pull-out resistance. This combination effectively suppresses fretting wear and loosening tendency under dynamic loads or thermal cycling environments, resulting in longer maintenance-free cycles for engineering projects.
Another key advantage is the one-sided operability and low-damage installation. Embedding can be completed without complex clamping or secondary processing, making it particularly suitable for automated assembly lines or on-site repair scenarios. Professional buyers will find that this advantage reduces overall assembly risk and shortens commissioning time, thus translating into significant process competitiveness in modern manufacturing with high-variety, low-volume production, rather than relying on additional tooling investment.
Design Advantages: Macroscopic Efficiency of Micro-Geometry
| Interlocking Mechanics of Knurled Finish | Unlike the screw-in characteristics of helical knurling, our knurled finish design is specifically designed for axial press-in. The knurled tooth profile is geometrically optimized, exhibiting sharp tooth peaks and reasonable tooth depth. When the Slotted Knurled Press-In Pin is pressed into the pilot hole, the knurled tooth peaks cut into the substrate (such as cast aluminum, engineering plastics, or steel), forming a forced interlock of "metal to metal" or "hard to soft." This design provides torsional and pull-out resistance far exceeding that of smooth locating pins, ensuring that the positioning reference never drifts under vibration or impact loads. |
| Functional Extension of Flat Slots | The flat slot design is not merely decorative. In deep-hole operations or confined spaces, the flat slot allows for auxiliary installation or adjustment using a standard flathead screwdriver, greatly improving assembly flexibility and tolerance. Furthermore, in certain specific fixture designs, the slotted groove can also serve as a vacuum suction slot, adapting to the gripping needs of automated robotic arms and providing excellent process compatibility for unmanned production lines. |
| Precise Guide Length Design | To prevent tilting during pressing, we designed a standardized smooth guide post at the front end of the knurled section. The surface finish and dimensional tolerances of this section are extremely strictly controlled to ensure that the Slotted Head Knurled Locating Stud can smoothly enter the base hole in a vertical posture, avoiding knurling breakage or base hole deformation caused by uneven force, thus guaranteeing the reliability of positioning accuracy. |
