FAQ
What is the difference between property classes 8.8, 10.9, and 12.9 for a 10 hex bolt?
These numbers indicate the bolt's grade or property class. The first number multiplied by 100 represents the minimum tensile strength in MPa (e.g., 8.8 = 800 MPa). The second number is the ratio of the yield strength to the tensile strength. A 12.9 10 hex bolt is the strongest, followed by 10.9 and 8.8. Selection depends on the required clamp force and service conditions of the application.
Can I get a 10 hex bolt with corrosion resistance for outdoor use?
Absolutely. For outdoor or corrosive environments, we recommend specifying a finish such as hot-dip galvanizing (HDG) or a mechanical galvanizing. These provide a thick, sacrificial zinc layer that offers excellent long-term protection against rust.
Do you supply matching nuts and washers?
Yes, we provide complete fastener kits. It is crucial to use a nut of the same or higher property class as the bolt (e.g., a Grade 10 bolt requires a Grade 10 nut) to ensure the assembly achieves its full strength potential. Hardened washers are also available.
What is the standard thread pitch for an M10 bolt?
The standard (coarse) thread pitch for an M10 metric bolt is 1.5 millimeters. A fine pitch variant, such as M10 x 1.25, is also available for applications requiring finer adjustment or where vibration resistance is enhanced by a finer thread.
What are the packaging options?
We offer packaging tailored to B2B needs, including bulk boxes (e.g., 100kg cartons), smaller master cartons, or even custom-branded packaging for OEM clients. All packaging is designed to prevent damage and corrosion during transit and storage.
