Galvanized Steel Fasteners for Differential Use: The differential cover bolts are formed from galvanized steel and measure M8-1.25x20mm. This metal choice provides a balance of strength and rust protection. It is suited for the temperature and vibration levels found in typical differential assemblies
Precision Fit: A rear differential cover bolt is machined to precise dimensions so that the threads engage smoothly and the bolt seats correctly. Accurate alignment between the cover and housing helps maintain proper drivetrain geometry during working
Stable Attachment Under Load: With a robust body and 1.25mm thread spacing, the diff cover bolts deliver consistent clamping force after installation. They are less likely to back out over time, which helps protect the gears and bearings inside the differential from movement-related wear
Supports Gasket Compression and Sealing: The rear differential cover bolt, when torqued appropriately, applies steady pressure across the gasket surface. This helps create a barrier against oil leaks at the cover seam, supporting adequate lubrication of internal components
10mm Hex Head for Common Tools: These differential cover bolts have a 10mm hex drive that works with standard socket sets and wrenches. The familiar size allows for quick installation or replacement without specialized sockets, making the process accessible for general maintenance work
