Product type
Hex bolts are fasteners characterized by their hexagonal heads, designed for use with a wrench or socket. They are typically made from materials such as carbon steel, stainless steel, or alloy steel, which provide strength and durability. Hex bolts are commonly used in a variety of applications where a secure fastening is required, including machinery assembly, construction, and automotive repairs.
| Material | Carbon steel, stainless steel, or alloy steel |
| Standard sizes | M6 to M30 |
| Thread pitch | Coarse and fine threads available |
| Finish | Zinc plated, black oxide, or plain |
| Strength grades | Grade 2, Grade 5, Grade 8, and metric grades |
When selecting hex bolts, consider the material and strength grade required for your application to ensure safety and durability. It's important to specify the correct thread size and pitch, as well as any necessary finishes to resist corrosion. Additionally, provide the quantity needed for your project to receive an accurate quote.

Coarse threads have a larger pitch and are easier to install, while fine threads provide better tension and are used in precision applications.
Yes, but it is recommended to use corrosion-resistant materials or finishes for outdoor use.
A wrench or socket that matches the size of the hex head is required for installation.
Yes, hex bolts are available in various lengths to accommodate different thicknesses of materials.
Measure the thickness of the materials being fastened and choose a bolt that is long enough to provide sufficient engagement.
Tensile strength can vary widely based on the material and grade, typically ranging from 60,000 psi to over 150,000 psi.
