S-90911A637 3/8"-16 x 3" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Grade 5 classification and 120,000 psi tensile strength, ensuring reliable performance under high stress.
• Superior corrosion resistance provided by the zinc-plated steel construction, extending the bolt's service life in harsh agricultural and industrial environments.
• Secure anti-rotation locking due to the square neck design, which prevents the bolt from turning during installation and under vibration.
• Optimized for easy installation with a coarse 3/8"-16 UNC thread and Class 2A fit, allowing for quick assembly and reduced risk of cross-threading.
• Flush mounting capability with its standard 82° flat head profile, creating a smooth surface that minimizes snagging in equipment.
• Controlled thread engagement with a partially threaded shank and a minimum 1" thread length, providing flexibility for various material thicknesses.
• Consistent quality and reliability backed by compliance with ASME B18.9 and SAE J429 standards, ensuring interchangeability and performance.

Professional Applications & Engineering Value

This Grade 5 Plow Bolt is engineered to address the rigorous demands of agricultural machinery, such as plow shares and cultivators, where high-impact loads and abrasive conditions are common. The zinc-plated steel material offers a robust barrier against rust and corrosion, significantly enhancing durability in outdoor and moisture-rich environments. The square neck is a critical feature that locks securely into the mating part, eliminating rotation and maintaining alignment during operation, which is vital for equipment safety and longevity. Its 3/8"-16 UNC coarse thread and partially threaded design ensure strong holding power while allowing for adjustments in assembly. By integrating these elements, this bolt provides a dependable heavy-duty fastening solution that reduces maintenance frequency and downtime in industrial and agricultural applications.
