S-90934A911 5/8"-11 x 2 3/4" SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Grade 8 classification and 150,000 psi tensile strength, ensuring reliable performance under high stress.
• Superior corrosion resistance provided by the zinc yellow-chromate plating on steel, extending the bolt's service life in harsh environments.
• Effective anti-rotation and secure fastening due to the integrated square neck design, which prevents the bolt from turning during installation and operation.
• Optimized for easy installation and high clamping force with a coarse 5/8"-11 UNC thread and Class 2A fit, facilitating quick assembly.
• Enhanced durability and wear resistance from the Rockwell C33 hardness, making it suitable for high-impact and abrasive conditions.
• Versatile partial threading allows for a non-threaded shank section to act as a shear plane, ideal for applications requiring precise clamping.
• Industry-standard compliance meeting SAE J429 specifications, ensuring quality and interchangeability for professional use.

Professional Applications & Engineering Value

This Grade 8 plow bolt is engineered to address critical challenges in agricultural and industrial equipment, where vibration, heavy loads, and exposure to corrosive elements are common. The zinc yellow-chromate plated steel construction provides a robust barrier against rust, significantly reducing maintenance downtime. The square neck design is a key feature that locks the bolt securely in place, preventing rotation in mounted components like plow blades and heavy machinery attachments. With its coarse UNC threads and partial threading, it ensures rapid installation and reliable grip in high-stress joints, making it an essential heavy-duty fastener for applications demanding both strength and longevity.

Specification Summary & Compliance

This plow bolt features a 5/8"-11 UNC coarse thread with a Class 2A fit for standard tolerance and easy assembly. It is manufactured from steel with a Rockwell C33 hardness and meets SAE J429 specifications for Grade 8 fasteners, ensuring consistent quality and performance. The product complies with industry standards for dimensional accuracy and is suitable for use in regulated environments, though specific declarations for RoHS or REACH should be verified per batch.
