1/3Knurled Wheel Hub Stud Bolts
Engineered for high-torque automotive and heavy machinery applications, our Class 10.9 Black Oxide Wheel Hub Stud Bolts feature a precision-machined straight-knurled shank underneath a low-profile round head. Designed to press firmly into hub assemblies, the knurling prevents spin during installation and wheel mounting, while the high-tensile alloy steel construction with a durable black finish provides exceptional shear strength and reliable performance under severe driving conditions.

Product description
Class 10.9 Black Oxide Knurled Wheel Hub Stud Bolts
- Class 10.9 High Strength: Clearly stamped with the 10.9 strength class mark on the flat round head, guaranteeing superior tensile strength (1000 MPa) and high yield resistance required for critical automotive and industrial load-bearing joints.
- Anti-Rotation Knurled Shank: Features precision straight knurling under the head that bites securely into the hub flange hole, preventing the bolt from spinning when tightening or loosening lug nuts.
- Surface Treatment: Coated with a high-grade black oxide / phosphate finish, offering sleek aesthetics, excellent anti-galling performance, and improved resistance against corrosion and oxidation.
- Head Design: Low-profile, smooth round head provides uniform pressure distribution against the back of the hub assembly without interfering with surrounding components.
- Precision Machined Threads: Clean, durable metric threads ensure smooth engagement, high fatigue resistance, and maximum clamp load retention.
- Applications: Ideal for passenger cars, light trucks, commercial vehicles, trailers, brake rotor/drum assemblies, and heavy machinery wheel hubs requiring press-in stud replacement.
