High-Strength 17mm Hex Bolt for Demanding Industrial Applications
In the world of heavy machinery, structural fabrication, and large-scale construction, the integrity of every connection is paramount. Our premium-grade 17mm hex bolt is engineered to meet the rigorous demands of these sectors, providing a reliable, high-strength fastening solution. Designed for professionals who cannot afford compromise, this bolt offers exceptional shear and tensile strength, superior corrosion resistance, and consistent dimensional accuracy. It is the cornerstone fastener for assemblies where safety, durability, and performance are non-negotiable.
Product Overview
Our 17mm hex bolt is a heavy-duty fastener characterized by its six-sided (hexagonal) head, which allows for high-torque application with standard wrenches and sockets. With a nominal diameter of 17mm, it fills a critical niche between M16 and M20 bolts, offering an optimal balance of strength and size for numerous industrial applications. Manufactured from high-quality alloy steel and subjected to stringent heat treatment processes, this bolt achieves grade 8.8 or higher specifications, ensuring it performs reliably under sustained load and vibration. Available in various lengths and finishes, including hot-dip galvanized and zinc-plated, it is built to withstand harsh environmental conditions.
Key Features
- Exceptional Mechanical Properties: Manufactured to ISO 898-1 or ASTM A449 standards, ensuring consistent Grade 8.8 (or equivalent) strength for high load-bearing capacity.
- Precision Engineering: Rolled threads for superior fatigue resistance and accurate fit with matching nuts, reducing the risk of cross-threading.
- Robust Corrosion Protection: Options include hot-dip galvanizing for maximum longevity in outdoor or corrosive environments, and plain or zinc-plated finishes for general use.
- Wide Compatibility: The standardized 17mm hex head is compatible with common industrial wrench sets, facilitating efficient installation and maintenance.
- Rigorous Quality Assurance: Each batch undergoes dimensional checks, hardness testing, and proof load testing to guarantee performance.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a Grade 8.8 and a Class 10.9 17mm hex bolt?
A: The grade/class indicates the bolt's strength. A Grade 8.8 bolt has a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. A Class 10.9 bolt is stronger, with a minimum tensile strength of 1000 MPa and yield of 900 MPa. Choose 10.9 for higher-stress, critical applications, while 8.8 is excellent for general heavy-duty use.
Q2: Can I use a standard 17mm wrench with all your hex bolts?
A: Yes. Our bolts are manufactured to standard dimensional specifications, with a width across flats of 27mm for a 17mm diameter bolt. This ensures compatibility with standard metric wrench and socket sets.
Q3: Which finish is best for outdoor marine environments?
A: For highly corrosive environments like marine or coastal applications, we strongly recommend hot-dip galvanized (HDG) or specialized coatings like Geomet®. These provide a thick, sacrificial layer of zinc that offers superior, long-term protection compared to standard zinc plating.
Q4: Do you supply matching nuts and washers?
A: Absolutely. We provide full fastener kits. We recommend and supply hex nuts and hardened washers of the same grade and finish as the 17mm hex bolt to ensure optimal performance and corrosion protection of the entire joint assembly.
Q5: What is your lead time for large custom orders?
A: Lead times vary based on specification and quantity. For standard custom items (e.g., non-standard lengths), we typically ship within 2-3 weeks. For complex custom orders involving special material or coating, our team will provide a precise timeline upon quotation. We prioritize clear communication throughout the process.
