Description
The bolts holding your rims to the wheel discs carry tremendous loads - literally supporting the entire weight of your tractor plus implements. This rim-to-disc bolt kit provides the high-strength fasteners needed for secure wheel assembly, preventing the catastrophic failures that occur when inferior bolts stretch, break, or work loose under heavy loads.
Key Features
- Heavy-duty 5/8" UNF thread x 2-7/8" length
- Complete kit includes bolt, nut, and washer
- Shoulder design provides proper alignment and load distribution
- Sold individually - order quantity needed
- High-tensile construction for wheel mounting applications
Critical Fasteners for Wheel Safety
Rim-to-disc connections endure extreme forces that would destroy ordinary bolts. Every bump transmits shock loads through these fasteners. Turning with heavy implements creates tremendous side forces. The constant flexing from loaded tires tries to work bolts loose. Your tractor pulling a loaded grain cart, pushing silage with a blade, or carrying a heavy loader bucket - all depend on these bolts maintaining their grip. The 5/8" UNF specification provides the strength needed, while the 2-7/8" length ensures full thread engagement for maximum holding power.
Understanding Rim Bolt Failure
Wheel bolt failures rarely happen suddenly - they develop over time through fatigue and loosening. Insufficient torque allows microscopic movement that enlarges bolt holes. Over-torquing stretches bolts beyond their elastic limit. Corrosion weakens the steel and prevents proper torque. Missing washers concentrate forces, causing galling and failure. The shoulder design on these bolts provides precise alignment, preventing the misalignment that accelerates wear. Once bolts begin failing, loads transfer to remaining fasteners, creating a cascade effect that can result in complete wheel separation.
Installation for Maximum Security
Proper installation prevents wheel failures that range from inconvenient to catastrophic. Clean all threads thoroughly - rust or dirt gives false torque readings. Inspect disc bolt holes for elongation or cracking that indicates fatigue. Use the included washers to distribute loads properly; missing washers guarantee problems. Apply specified torque in a star pattern through multiple stages for even loading. Never use impact wrenches for final tightening - only calibrated torque wrenches ensure proper clamping. Recheck torque after initial operation as new installations often settle. Mark bolt positions with paint to monitor any movement. Keep spare bolts on hand - discovering damaged bolts during tire changes prevents costly delays.
These bolts literally hold your wheels on. Don't compromise safety to save a few dollars on the fasteners that prevent catastrophic wheel separation.
