Fasteners are indispensable in various industries, serving as fundamental components in construction, machinery assembly, and product manufacturing. At CNV Engineering, we offer an extensive range of fasteners, crafted from various high-grade materials to suit specific industry requirements.

Materials used in Fasteners

Our fasteners are available in several material grades, each selected for its unique properties and suitability for different applications:

Grades Gr8.8, 10.9, 12.9: Ideal for automotive and general engineering, known for their high tensile strength and durability.

B7, 2H: Commonly used in applications requiring robust fasteners capable of withstanding high pressures and temperatures.

B8MA, NACE: Special stainless steel grades, suitable for corrosive environments, often used in the valve- oil & gas industries.

SS410 (Stud only): Provides good strength and corrosion resistance, suitable for specific applications like stud bolts.

SS202, SS304, SS304L, SS316, SS316L: Stainless steel variants offering a balance of corrosion resistance and strength, used across various sectors including aerospace and food processing machinery.

Types of Fasteners and Their Applications:

Type of Fastener	Description	Common Applications
Hex Bolts	Characterized by a hexagonal head, used for fastening two or more parts together.	General engineering, construction.
Hex Nuts, Heavy Hex Nuts	Typically used in conjunction with a bolt or screw to secure components.	Automotive, machinery assembly.
Square Nuts	Four-sided nuts offering a larger surface area against the part being fastened.	Railways, heavy machinery.
Nylock Nuts	Incorporate a nylon insert to prevent loosening under vibration.	Aerospace, automotive.
Allen Bolts (Socket Head Cap Screws)	Contain a socket for a hex key, allowing for tighter fastening.	Precision equipment, electronics.
Countersunk Bolts	Designed to sit flush with the surface of the material.	Aerospace, decorative applications.
Washers, Spring Washers	Distribute the load or provide a locking function.	Broad range of industrial applications.
Custom Made Profile Washers	Tailored to specific requirements for unique applications.	Specialized machinery, bespoke projects.
Eyebolts	Used for attaching a securing eye to a structure, enabling lifting or rigging.	Construction, lifting equipment.

Industry-Specific Fastener Solutions:

Pump and Valve Industries: Special grades like NACE and B8MA are used for their corrosion resistance and durability in challenging environments.

Railways and Aerospace: Stainless steel fasteners (SS grades) are chosen for their strength and resistance to environmental factors.

Automotive and General Engineering: Grades Gr8.8, 10.9, and 12.9 are preferred for their high tensile strength and resilience.

At CNV Engineering, we understand the critical role fasteners play in various industries. Our extensive range of high-quality fasteners, combined with our expertise in material selection and application-specific design, ensures that we can provide the ideal fastening solution for any project requirement.
