Double Knurl Head Stepped Locating Pin for Assembly

Qimao Metal Manufacturer offers high-quality Double Knurl Head Stepped Locating Pin for Assembly for customers. The stepped semi-hollow pin is engineered for high-performance drivetrain applications. Its unique hollow core allows oil flow for lubrication, while the stepped geometry provides precise axial positioning. The knurl pattern is a straight diamond, about 0.25mm deep. Head diameters range from 8mm up to 20mm. Steps can drop as little as 1mm or as much as 5mm per step. Every pin gets a quick visual check on the knurls – missing teeth mean a reject.

The product is used in dual-clutch transmission hubs to lock synchronizer sleeves, as shear pins in PTO shafts (fracturing cleanly without metal contamination), and for aligning chain sprockets in transfer cases. Also serves as locating pins in heavy fixtures and range shift rails in tractors. A smaller version is available for EV park lock pawls.

Made from case-hardened alloy steel with anti-corrosion coating. Reduces weight, improves lubrication, and enhances failure safety.

Product Parameter (Specification)

Product Feature

1. First, the Double Knurl Head Stepped Locating Pin for Assembly gives you two grip zones instead of one. If your fingers are oily, the second band still catches.

2. Second, the stepped design means one pin handles two locating bores – less tooling to keep track of.

3. Third, the head is slightly oversized compared to the largest step, so you can feel when it's seated fully.

4. Fourth, we leave a tiny radius under the head, not a sharp corner. That stops stress cracks from forming over time.

5. Fifth, the locating diameters hold a tolerance of plus or minus 0.01mm. That's tight enough for most jigs and fixtures without being impossible to press in by hand.

Application

1. These pins most often in quick-change fixture plates where operators swap parts every few minutes. The Double Knurl Head Stepped Locating Pin for Assembly lets them pull the pin out with bare fingers, no tools.

2. Another common spot is in assembly line pallets that carry different product families – one stepped pin can locate either version.

3. They also show up in inspection fixtures for castings where the bore sizes vary slightly between batches. On manual clamp stations, the knurled head gives you a good grip even with gloves on.

4. Some customers use them as adjustable stops on welding tables – just turn the pin to a different step depth.

Our Advantages

1. We run our Double Knurl Head Stepped Locating Pin for Assembly on dedicated lathes with hydraulic pressure control, not hand-fed machines. That means every knurl band comes out the same depth across the whole batch.

2. The double knurl setup tooling is already paid for – so no extra charge for the second band.

3. Every lot gets a first-article inspection on an optical comparator, and we keep the record for two years.

4. If a knurl looks shallow, we catch it before packing. You can call our shop floor direct – no phone tree.
