Value Collection C737822 Plow Bolt 1-1/4-7 Unc Grade 8

Product Description

The VALUE COLLECTION C737822 is a Grade 8 alloy steel plow bolt designed for high-strength fastening in heavy equipment, earth-moving machinery, and industrial fabrication applications. With a 1-1/4-7 UNC thread size and an overall length of 4.5 inches, this bolt meets the dimensional and mechanical requirements for demanding structural connections. The domed head profile is the defining characteristic of the plow bolt design, sitting flush or below the mounting surface to prevent interference with soil, aggregate, or material flow. Sold in a package quantity of 5, this fastener is supplied uncoated. Licensed tradespeople and equipment maintenance technicians are the primary installers.

Plow bolts are used in agricultural equipment, construction machinery, conveyor systems, and wear-plate assemblies where a low-profile fastening solution is required. The flat or countersunk mounting surface on the receiving component indexes against the domed head to prevent rotation during installation and service. The 1-1/4-7 UNC coarse thread pitch is well suited to thick steel plates and castings. Grade 8 mechanical properties make this bolt appropriate for joints subject to significant shear, vibration, or tensile loading.

Key Features

• Grade 8 alloy steel construction for high tensile and proof load capacity
• 1-1/4-7 UNC coarse thread for reliable engagement in heavy plate and casting applications
• 4.5-inch overall length accommodates thick structural assemblies and wear-plate stacks
• Domed head profile indexes against countersunk seats to resist rotation without a wrench on the head
• Uncoated finish — field coating or plating can be applied as required by the application
• Sold in a quantity of 5 per package with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or service fastener for heavy equipment assemblies, wear plates, and structural joints requiring a 1-1/4-7 UNC Grade 8 plow bolt with a 4.5-inch overall length.

Installation Notes

Installation is typically performed by equipment mechanics or millwrights following the equipment manufacturer's torque specifications for Grade 8 fasteners at this thread size. Ensure the mating countersunk or domed seat is clean and free of debris before seating the bolt head, as proper head indexing is critical to preventing rotation. Always use a calibrated torque wrench and a hardened flat washer under the nut where specified. Follow applicable ASME or equipment OEM fastener installation standards.
