This guide provides a detailed overview of China M10 hex bolts, covering their specifications, applications, materials, quality standards, and sourcing options. We'll explore the factors to consider when selecting these fasteners and offer insights to help you make informed purchasing decisions. Learn about different grades, surface treatments, and common uses for M10 hex bolts in various industries.

Understanding M10 Hex Bolts

What is an M10 Hex Bolt?

An M10 hex bolt is a type of threaded fastener with a metric size designation of M10. The M indicates a metric thread, and 10 represents the nominal diameter in millimeters. The hex refers to the hexagonal head shape, which allows for tightening with a wrench. These bolts are widely used in a variety of applications due to their strength and versatility.

Key Specifications of M10 Hex Bolts

Several key specifications define China M10 hex bolts. These include:

• Thread Pitch: The distance between adjacent threads. Common pitches for M10 bolts include 1.5mm and 1.25mm.
• Thread Length: The length of the threaded portion of the bolt.
• Bolt Length (Overall Length): The total length of the bolt, including the head and threaded portion.
• Head Height: The height of the hexagonal head.
• Material: Commonly made from carbon steel, stainless steel, or alloy steel, each offering different properties and corrosion resistance. The choice of material significantly affects the bolt's strength and durability.
• Grade: Indicating tensile strength. Common grades include 4.8, 8.8, and 10.9, with higher grades signifying greater strength. Understanding the grade is crucial for selecting the appropriate bolt for your application.
• Surface Treatment: Processes like zinc plating, galvanizing, or black oxide coating enhance corrosion resistance and improve appearance. These treatments extend the bolt's lifespan, especially in demanding environments.

Choosing the Right M10 Hex Bolt

Factors to Consider

Selecting the appropriate China M10 hex bolt involves careful consideration of several factors:

• Application: The intended use of the bolt dictates the required strength, material, and surface treatment.
• Material Compatibility: Ensure the bolt material is compatible with the materials being joined to prevent corrosion or weakening.
• Environmental Conditions: Consider exposure to moisture, chemicals, or extreme temperatures when selecting the material and surface treatment.
• Load Requirements: The bolt must have sufficient tensile strength to withstand the applied load. Refer to engineering standards for appropriate bolt selection based on load calculations.
