Designed for professionals who cannot compromise on quality, these bolts are manufactured to exacting international standards, ensuring consistent performance in the most challenging environments. This product page details the specifications, benefits, and ideal use cases for our premium-grade 17mm hex head bolts.
Product Overview
Our 17mm hex head bolts are heavy-duty fasteners characterized by a six-sided (hexagonal) head that provides superior torque application with common tools like wrenches and sockets. The 17mm hex head bolt size refers specifically to the distance across the flats of the bolt head, a critical dimension for tool compatibility and installation. These bolts are typically available in a range of diameters, lengths, and material grades to suit various structural and mechanical requirements. They are a fundamental component in applications where a secure, high-strength threaded connection is essential to maintain structural integrity under dynamic loads and stress.

FAQ
What does "17mm hex head bolt size" mean?
It refers to the width across the flats of the bolt's hexagonal head, which is 17 millimeters. This is the dimension that determines the size of the wrench or socket needed to tighten or loosen the bolt (e.g., a 17mm wrench).
What is the typical diameter range for bolts with a 17mm head?
Bolts with a 17mm hex head bolt size commonly correspond to thread diameters such as M10, M12, and M14. The relationship between head size and thread diameter is standardized to ensure sufficient bearing surface and strength.
How do I choose between Grade 8.8 and 10.9?
Grade 8.8 is a medium-strength bolt suitable for most general industrial applications. Grade 10.9 is a high-strength bolt designed for critical, high-stress applications like structural steel or dynamic machinery. The choice depends on the required clamp load and safety factor of your design.
Can you provide bolts with specific certifications?
Yes. We can supply bolts with full traceability and material certifications (e.g., 3.1 Material Certificates per EN 10204) and ensure compliance with specific project standards like CE marking for construction or certifications for the oil & gas industry.
What are the packaging and minimum order quantities (MOQ)?
We offer flexible packaging from small boxes to palletized bulk packs. MOQs are typically low for standard items to accommodate sample requests and trial orders, with significant volume discounts available for large project-based purchases.
