Value Collection 221148MSC Bucket Tooth Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION 221148MSC is a Grade 8 alloy steel bucket tooth bolt designed for heavy-duty fastening applications in construction, excavation, and earthmoving equipment. Threaded to the 5/8-11 UNC standard with an overall length of 2.25 inches, this bolt meets the dimensional and mechanical requirements set by ASME B18.9 and SAE J429. Grade 8 alloy steel provides high tensile strength and shear resistance, making it suited for the demanding load cycles common in bucket tooth and ground-engaging tool assemblies. The uncoated finish is standard for this fastener class and is compatible with field replacement workflows.

This bolt is used in the attachment of bucket teeth and cutting edges on excavator buckets, loader buckets, and similar ground-engaging assemblies. It is a common replacement fastener for field service crews and equipment maintenance technicians working on light to heavy construction machinery. The 5/8-11 UNC thread form is a widely used coarse-thread standard, making this bolt straightforward to source and install during scheduled maintenance or emergency field repairs.

Key Features

• 5/8-11 UNC coarse thread per ASME B18.9 and SAE J429 standards
• 2.25-inch overall length suited for standard bucket tooth mounting configurations
• Uncoated finish for compatibility with standard field installation and replacement
• Sold individually, allowing single-unit replacement without excess stock

Compatibility

Designed as an OEM-style replacement bucket tooth bolt for ground-engaging tool assemblies using 5/8-11 UNC fasteners on construction and excavation equipment.

Installation Notes

Installation is typically performed by equipment maintenance technicians or field service crews. Always power down and lock out the equipment before servicing bucket tooth assemblies. Use a calibrated torque wrench and follow the equipment manufacturer's torque specifications for Grade 8 fasteners of this thread size. Inspect mating threads and nut seats for wear or damage before installing a replacement bolt.
