Value Collection R50000218 Plow Bolt 1/2-13 Unc Grade 5

Product Description

The VALUE COLLECTION R50000218 is a Grade 5 steel plow bolt designed for heavy-duty fastening applications where a flush, flat-head profile is required. With a 1/2-13 UNC thread size and an overall length of 1.5 inches, this bolt meets ASME/ANSI B18.9 and SAE J429 standards. The uncoated steel construction provides solid structural integrity for demanding mechanical and equipment installations. Plow bolts are recognized by their countersunk head geometry, which resists loosening under vibration and sits flush with mating surfaces to prevent snagging or interference.

This plow bolt is commonly used in agricultural equipment, construction machinery, and industrial fabrication where conventional hex-head bolts would protrude and create clearance issues. The 1/2-13 UNC coarse thread pattern offers good resistance to cross-threading and provides reliable clamping force across a wide range of base materials. Contractors, equipment technicians, and maintenance professionals working on loader blades, grader blades, and similar wear-surface assemblies will find this bolt a standard fit for many field and shop repair tasks.

Key Features

• Grade 5 steel construction meets SAE J429 minimum tensile and proof load requirements
• 1/2-13 UNC coarse thread for strong thread engagement and field replaceability
• 1.5-inch overall length suits shallow countersunk fastening applications
• Flush countersunk head profile minimizes snag points on working surfaces
• Uncoated finish — suitable for use as-is or with field-applied coatings
• Conforms to ASME/ANSI B18.9 dimensional standards

Compatibility

Designed as an OEM-style replacement plow bolt for agricultural, construction, and industrial equipment applications requiring a 1/2-13 UNC Grade 5 countersunk fastener conforming to ASME/ANSI B18.9.

Installation Notes

Installation should be performed by a qualified mechanic or equipment technician familiar with fastener torque requirements for Grade 5 hardware. Always de-energize and lock out equipment before replacing wear-surface fasteners. Use the appropriate countersunk hole geometry to ensure full head seating and flush surface contact. Do not mix grade ratings within a fastener assembly.
