4Pcs Disc Brake Rotor Retaining Screws - BMW X5, Z4, 328i (OE 34211161806)

Disc Brake Rotor Retaining Screws for BMW X5, Z4, and 328i

This is a set of 4 disc brake rotor retaining screws, OE number 34211161806 (also cross-referenced to 34111157343), built for the BMW X5, Z4, and 328i. If you've pulled a rotor off during a brake job and found the original screw stripped, snapped, or seized in place from years of rust, this set gives you a clean, correctly-threaded replacement rather than something improvised from a hardware store bin.

What This Small Part Actually Does

It's easy to overlook rotor retaining screws when they're this small, but their job matters more than their size suggests. These screws hold the rotor snug against the wheel hub before the wheel goes back on, keeping the rotor from rattling or shifting out of position during assembly and while the vehicle is off the ground. Once the wheel is torqued down, the wheel itself takes over most of the clamping duty, but a stripped or missing retaining screw makes rotor removal and reinstallation far more frustrating than it needs to be, and can let a rotor sit slightly off-center during service.

A Note on Fitment

This part number is commonly listed against the BMW E36, E46, E82, and E88 chassis in parts catalogs, and you may see it cross-referenced that way elsewhere. Based on the confirmed application data we have on file, this screw set is verified to fit the BMW X5 (2000-2016), Z4 (2003-2016), and 328i (1999-2000 and 2007-2015). We'd rather tell you exactly what's confirmed than repeat an unverified chassis list, so if your BMW isn't one of these three models, please check your original screw's thread pitch and head diameter against this listing, or reach out before ordering.

OE and Manufacturer Numbers

This set is built to OE/OEM numbers 34211161806 and 34111157343, with manufacturer part number BACB12-002006 also on file. Matching any of these against your BMW's parts documentation or the stamping on your original screw is the surest way to confirm fitment.

Why Replace Rather Than Reuse

A rotor screw that's already stripped or corroded tends to get worse, not better, the next time someone tries to remove it. Wikipedia's disc brake article notes that a rotor's retaining bolts have to be tightened progressively and evenly to avoid warping the disc, which is a good reminder that even small brake hardware plays a role in how evenly your rotor sits and wears. Starting a brake job with fresh, correctly-fitting screws instead of fighting a rounded-off original saves time and avoids damaging the hub threads.

Installation

These screws thread into the hub and pull the rotor snug against the hub face; a screwdriver or small socket is usually all that's needed, though a touch of anti-seize on the threads makes the next removal easier. They're meant to keep the rotor positioned during handling and wheel installation, not to replace properly torqued lug nuts or wheel bolts, so always finish the job by torquing your wheels to your BMW's specification.
