Treated Steel Bleeder Screw, 0.92 in., 1/4 in.-28 Thread
Dorman 6446-BX is a universal brake bleeder screw for service jobs where a missing, damaged, or fatigued bleeder is keeping air trapped in the hydraulic brake system. Its treated steel construction, silver finish, 0.92 in. length, and 1/4 in. - 28 thread size give technicians and DIY installers concrete dimensions to verify before installation.
Dorman 6446-BX Technical Specifications:
- Treated steel construction helps resist corrosion during regular brake service and long-term exposure at the caliper or wheel cylinder.
- 0.92 in. overall length and 1/4 in. - 28 thread size support accurate fit checks before ordering or installation.
- No integrated check valve, so bleeding should be performed with the standard service method required for the vehicle.
- Universal fitment is intended for applications that match the listed thread size, length, and bleeder design rather than a specific year, make, or model.
Use this replacement when the original bleeder screw is missing, rounded, corroded, or no longer sealing correctly. Always confirm the thread size and length against the factory bleeder before installation.
