We offer These Alloy Steel Gr 12.9 Bolts as per DIN, ISO, JIS or ANSI Standard.
High Strength: Grade 12.9 bolts are known for their exceptional strength, making them suitable for heavy load-carrying applications. They are often used in high-stress environments where standard bolts can deform or fail.
Excellent toughness: Alloy steel grade 12.9 bolts exhibit excellent toughness, allowing them to withstand shock and fatigue without breaking. This property is important where dynamic loads are common.
Water resistance: Alloy steel grade 12.9 bolts are often coated or treated to increase corrosion resistance. This makes them suitable for use outdoors or in harsh environments where exposure to water, chemicals, or other corrosive agents is a concern.
Heat resistance: These fibres can maintain their mechanical properties over various temperatures. This characteristic is important where temperature fluctuations occur, such as in automotive, aerospace, and industrial machinery.
Durability: Due to their great strength and hardness, grade 12.9 bolts are extremely durable and have a long lifespan compared to lower-grade bolts. This durability eliminates the need for frequent replacements and saves time and maintenance costs.
Alloy Steel Gr 12.9 Bolts applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Automotive Industry: Grade 12.9 bolts are commonly used in engine assemblies, suspension systems, chassis and other critical automotive components where high tensile strength and resistant tensile strength are required
Structural Engineering: Applied to structural engineering projects such as bridges, buildings and infrastructure that provide strength and stability under heavy loads and adverse conditions
Oil and Gas Sector: Class 12.9 bolts are used in oil rigs, pipelines and refineries, where they must withstand harsh conditions, high pressures and corrosive weather
Aerospace and Security: These bolts find applications for protecting critical structures, aircraft parts and military vehicles in aerospace and security industries where lightweight and high strength are required
Heavy machinery: Used in the manufacture of heavy machinery and equipment, including construction machinery, mining machinery and agricultural machinery, where durable and reliable
Strength Requirements: Grade 12.9 bolts are known for their high tensile strength. Determine the maximum thickness and tension of your bolts in your application to ensure that Grade 12.9 bolts are suitable.
Thread Type and Size: Select a bolt with the appropriate thread type (e.g., coarse or fine) and size for your application to ensure fit and consistency
Heat Resistance: Make sure the bolts can withstand the heat of your application without compromising their mechanical properties. Grade 12.9 bolts are generally suitable for high-temperature applications, but make sure they meet your specific temperature requirements.
Corrosion Resistance: Consider the condition in which the bolts will be used. To contain water, chemicals, or other corrosive substances, select a bolt with appropriate corrosion resistance, such as a cover or a coating designed to resist corrosion.
