Value Collection 205218MSC Plow Bolt 5/8-11 Unc 4 in Grade 8

Product Description

The VALUE COLLECTION 205218MSC is a Grade 8 alloy steel plow bolt with a domed head, designed for high-strength fastening applications where flush or recrosunk head profiles are required. The bolt features a 5/8-11 UNC thread form and measures 4 inches overall length. Grade 8 alloy steel construction provides high tensile strength and shear resistance, meeting SAE J429 standards. This fastener is uncoated and suited for use in heavy equipment, agricultural machinery, and structural assemblies where a recessed domed head keeps the mating surface smooth and unobstructed. Installation is typically performed by equipment technicians and maintenance professionals.

Plow bolts are commonly used in earthmoving, grading, and agricultural equipment — particularly in cutting edges, blades, and wear plates where the domed head sits flush or slightly below the working surface to reduce wear and snagging. The 5/8-11 UNC thread size and 4-inch overall length make this fastener appropriate for medium-to-heavy plate thicknesses in those assemblies. This bolt ships in a minimum order quantity of 5 pieces, sold individually per package quantity of 1.

Key Features

• Grade 8 alloy steel construction meets SAE J429 for high tensile and proof load requirements
• 5/8-11 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 4 inches overall length suits medium-to-heavy plate fastening in blade and wear-plate assemblies
• Domed head profile keeps the working surface clear of protruding fastener heads
• Uncoated finish — suitable for applications where coating would interfere with fit or where field painting is applied

Compatibility

Designed as a standard-dimension plow bolt for use in agricultural equipment, road graders, bulldozer blades, and similar earthmoving or wear-plate assemblies requiring a 5/8-11 UNC domed-head fastener at 4 inches overall length.

Installation Notes

Installation should be performed by qualified equipment technicians following the equipment manufacturer torque specifications for Grade 8 fasteners at this thread size. Ensure mating surfaces and the bolt seat are clean and free of debris before assembly to achieve proper head seating. Use a hardened flat washer and Grade 8 compatible nut on the bearing side. Inspect threads for damage before installation and discard any bolts with rolled, crossed, or stripped threads.
