Qimao Metal Manufacturer’s Stop Pin Steel Material For Automotive Seat Slide is an essential, reliable T-shaped steel component for automotive seat slides—no springs or moving parts, but critical to preventing seat slides from pulling off tracks. With 8 years of manufacturing experience for seat frame assemblers and replacement suppliers, Qimao ensures consistent quality for both OEM and replacement needs.

How to use the products?

Step 1 — Get the old one out

If you're replacing a worn or broken stop pin, usually you can just drive it out with a punch from the opposite side. Some are pressed in tight. Some are loose because the hole got wallowed out over time. Use a little penetrating oil if it's stubborn.

Step 2 — Check the hole

Before you press the new, look at the mounting hole on the slide rail end. Is it still round? Any burrs? Run a drill bit through by hand just to clean it up if needed. We've seen installs fail because someone tried to press a new pin into a damaged hole.

Step 3 — Press the new pin in

Line up your new Stop Pin Steel Material For Automotive Seat Slide from Qimao Metal Manufacturer. Use a hammer or an arbor press. Tap it in straight — don't let it go crooked or you'll deform the shaft. It should be an interference fit. Not loose enough to spin, not so tight that you crack the rail.

Step 4 — Check the stop position

Slide the seat all the way back until it contacts the stop pin. It should hit solid with no wobble. If the seat passes over the pin, your pin is too short or the hole location is wrong.

Product Advantages

The Stop Pin Steel Material For Automotive Seat Slide from Qimao Metal Manufacturer won't break under normal use

We've seen cheap stop pins made from mild steel that bend after a few hundred cycles. Ours are machined from 1045 carbon steel or equivalent. Hardness is consistent. No soft spots.

The T-head doesn't shear off

Some manufacturers make the undercut too deep where the head meets the shaft. That's a stress riser waiting to fail. Our design keeps that radius generous. A seat slider hitting the pin at the end of travel puts force on that corner. Ours holds.

Diameter tolerance is actually held

Sounds basic, but you'd be surprised. We grind the shaft after turning, not before. So the diameter stays within 0.02mm from one piece to the next. That means a consistent press fit, not "this one is loose, this one is tight."

Order Operation Process

Step 1 — Tell us what you need

Send us the artwork, if you don't have them, send us a sample. Or just tell us the car model and which seat position. We might have the spec on file.

Step 2 — We quote within one business day

Usually faster. Our guy in the office checks emails three times a day. If you include " Stop Pin Steel Material For Automotive Seat Slide RFQ" in the subject line, it jumps to the front.

Step 3 — You approve the proforma invoice

30% deposit for new customers. We take bank transfer (T/T). For customers we've shipped to before, we can do net terms if the order is over $2000.

Step 4 — Production and inspection

Standard sizes ship in 2-3 days. Custom lengths take about a week. We check every batch with a go/no-go gauge for the diameter. No spot checking — every piece gets measured.

Step 5 — Packing and shipping

Small orders go in padded envelopes or small boxes. We've tried cheaper packing and had pins punch through the envelope during shipping. Learned that lesson. Now we tape the corners and add a second layer if the order is going overseas.

Step 6 — You get tracking

We send you the tracking number and a photo of the packed box. Some customers think that's unnecessary. Most appreciate knowing something actually shipped.
