In the demanding world of industrial assembly and construction, the integrity of every connection is paramount. Our M10 hex bolts are engineered to meet these rigorous demands, offering a reliable, standardized fastening solution for a vast array of heavy-duty applications. Characterized by their hexagonal head and 10mm nominal diameter, these bolts are a cornerstone component in machinery manufacturing, structural steelwork, automotive frameworks, and infrastructure projects. Designed for use with matching nuts and washers, they provide a secure, vibration-resistant joint capable of withstanding significant shear and tensile forces.
Product Overview
Our M10 hex bolts are manufactured to international standards, including ISO 4014/4017, DIN 933/931, and ASTM A325, ensuring global compatibility and performance reliability. Available in a comprehensive range of grades, materials, and finishes, they are versatile enough to suit environments from standard indoor assembly to corrosive outdoor settings. The familiar hexagon head design allows for high-torque application using common hand or power tools, making them a practical and efficient choice for high-volume assembly lines and on-site construction alike.

Frequently Asked Questions (FAQ)
What is the difference between property classes 8.8, 10.9, and 12.9 for M10 hex bolts?
Property class indicates the bolt's tensile strength. An 8.8 grade has a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. 10.9 offers 1000 MPa tensile and 900 MPa yield, while 12.9 provides 1200 MPa tensile and 1080 MPa yield. Higher grades are used for more critical, high-stress applications.
When should I choose stainless steel over carbon steel M10 bolts?
Choose stainless steel (typically A2-304 or A4-316) when your application is exposed to moisture, chemicals, or corrosive environments to prevent rust and ensure long-term integrity. Carbon steel with a protective coating (e.g., galvanizing) is more cost-effective for general-purpose use where corrosion is a lesser concern.
Do you supply matching nuts and washers with your M10 hex bolts?
Yes, we can supply full fastener kits. We offer matching hex nuts (ISO 4032), flat washers (ISO 7089), and spring washers (ISO 10683) in the same grade and finish to ensure optimal performance and galvanic compatibility in the joint assembly.
Can you manufacture M10 hex bolts to a specific custom length or non-standard finish?
Absolutely. We specialize in providing tailored solutions. We can produce M10 hex bolts in custom lengths, special thread lengths, unique markings, and with specialized coatings like dacromet or proprietary anti-corrosion systems to meet your exact project specifications.
What packaging options are available for bulk orders?
We offer a variety of packaging to suit your handling and storage needs, including bulk boxes (20-25 kg), smaller labeled cartons, or even pre-sorted kits on tape or in reels for automated assembly systems. All packaging is designed to prevent damage and corrosion during transit and storage.
