Value Collection 206218MSC Plow Bolt 3/4-10 Unc 4 in Grade 8

Product Description

The VALUE COLLECTION 206218MSC is a Grade 8 alloy steel plow bolt with a 3/4-10 UNC thread and an overall length of 4 inches. Plow bolts use a flat, countersunk head designed to sit flush with or below a mounting surface, preventing protrusion that could interfere with moving material or equipment contact surfaces. The uncoated finish is standard for applications where dimensional precision matters more than corrosion protection. This bolt meets SAE J429 standards for Grade 8 mechanical properties, providing high tensile strength for demanding structural and heavy-equipment fastening tasks. Mechanics and equipment technicians working on agricultural, construction, and earthmoving machinery are the primary installers.

Plow bolts are most commonly used in agricultural and construction equipment — including moldboards, cutting edges, blades, and wear plates — where a flush fastening surface is required to protect the bolt head from abrasion and impact. The 3/4-10 UNC coarse thread suits general structural assembly where rapid installation and reliable clamp load are priorities. The Grade 8 rating makes this bolt appropriate for high-stress joints on heavy equipment, earth-engaging attachments, and similar industrial applications where standard hardware grades are insufficient.

Key Features

• Grade 8 alloy steel construction meets SAE J429 for high tensile strength
• 3/4-10 UNC coarse thread for reliable engagement in structural assemblies
• 4-inch overall length suits common blade and wear-plate fastening depths
• Flat countersunk head profile sits flush to protect against abrasion and impact
• Uncoated finish maintains tight dimensional tolerances for precision fitment

Compatibility

Designed as an OEM-style replacement or service fastener for agricultural and construction equipment requiring 3/4-10 UNC Grade 8 plow bolts with a 4-inch overall length.

Installation Notes

Installation should be performed by qualified mechanics or equipment technicians familiar with high-strength fastener procedures. Always verify the mating nut or tapped hole is rated for Grade 8 loads before assembly. Clean threads and mating surfaces before installation, and use a calibrated torque wrench to achieve the correct clamp load per equipment manufacturer specifications. Do not substitute lower-grade hardware in Grade 8 applications.
