S-98930A229 M10 x 70 mm ISO 8678 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating, ideal for harsh industrial environments
• High tensile strength (110,000 psi) and Class 8.8 rating for reliable heavy-duty fastening applications
• Secure anti-rotation performance thanks to the integrated square neck design that prevents loosening under vibration
• Optimized for metric systems with M10 coarse threading (1.5mm pitch) ensuring easy installation and compatibility
• Precision threading (Class 6g fit) provides consistent engagement and reduces the risk of cross-threading
• Durable material hardness (Rockwell C22) offers excellent wear resistance and long-term structural integrity
• Partially threaded shank allows for effective clamping without thread interference in non-threaded sections

Professional Applications & Engineering Value

This M10 carriage bolt is engineered to address critical challenges in industrial assembly, construction, and machinery where vibration resistance and structural reliability are paramount. The zinc yellow-chromate plated steel construction provides a robust barrier against corrosion, extending service life in outdoor or chemically aggressive settings. Its square neck securely locks into materials during tightening, eliminating rotation and maintaining alignment without requiring additional locking components. With a Class 8.8 strength grade and coarse metric threading, it delivers consistent clamping force and ease of installation in heavy equipment, structural frameworks, and transportation applications. The partial threading design ensures that the unthreaded portion bears load efficiently, reducing stress concentrations and enhancing joint stability.

Specification Summary & Compliance

This carriage bolt adheres to ISO 8678 specifications, ensuring dimensional accuracy and performance consistency. Threading conforms to Metric coarse standards with a Class 6g tolerance for precise fit. The product meets common industry requirements for material and plating, with compliance to RoHS and REACH environmental directives where applicable. Manufactured from steel with Rockwell C22 hardness, it maintains 110,000 psi tensile strength as per Class 8.8 mechanical properties.
