The sinoboltco SNDP000003 series represents our core standard for precision taper locating dowel pins, meticulously engineered to optimize mechanical alignment repeatability. By executing a strict tolerance profile of +0.010 mm to +0.005 mm depending on nominal diameter sizing, these locating pins drastically reduce cumulative assembly clearance deviations.
Material Engineering and Hardness Properties: To satisfy distinct industrial environments, the SNDP000003 series is dual-channeled by material composition:
SUJ2 Bearing Steel Grade: Undergoes specialized atmospheric heat treatment to achieve a surface and core hardness of 58HRC. This configuration delivers maximum shear resistance and severe wear-performance under heavy cyclic loads, typical in progressive stamping dies and heavy automotive assembly fixtures.
Stainless Steel Grade: Specifically designated for corrosion resistance in chemically exposed, high-humidity, or wash-down environments. It effectively prevents mechanical seizing and oxidation inside precision mating holes, making it the ideal baseline for medical instrumentation, packaging machinery, and outdoor automation arrays.
Advanced Geometry and Lead-In Ergonomics: As illustrated in our technical specification sheet sinoboltco.jpg, each pin integrates a 15 degree entry chamfer paired with a masterfully machined rounded guide tip (R matches D). This exact geometric configuration ensures effortless, scratch-free press-fit insertion into precision holes, completely eliminating the component cracking or bore scoring risks common with crude, flat-edged pins. The chamfer height dimension (A) scales directly with the pin’s nominal diameter – ranging from 0.4 mm on micro-pins up to 3.5 mm on heavy-duty profiles – ensuring uniform stress distribution during initial entry.
