Knowledge Needed To Purchase U-shaped Bolts,As someone who wants to purchase U-bolts,
it is necessary to understand the following aspects of information to ensure the purchase of suitable and high-quality products:
1、 Basic specifications of U-bolts
Diameter: The diameter of a U-bolt is usually expressed as the diameter of its threaded portion, ranging from M6 to M64,
and may also be measured in inches (such as 1/4 ” to 2-1/2 ”).
Length: The length of the U-bolt depends on the usage requirements and can be any length.
Material: U-bolts come in various materials, commonly including carbon steel, stainless steel, etc.
Bolts made of different materials have different strengths and corrosion resistance, and should be selected according to the usage environment.
Surface treatment: The surface treatment methods for U-bolts include blackening, yellow zinc plating, white zinc plating,
hot-dip galvanizing, hot-dip galvanizing, Dacromet plating, etc. These treatment methods can improve the corrosion resistance and aesthetics of bolts.
2、 Technical requirements for U-bolts
Strength grade: The strength grade of U-bolts indicates their tensile strength, commonly including 4.6, 5.6, 6.8, 8.8, 10.9, 12.9, etc.
High strength bolts are typically used in situations that require significant tensile strength.
Thread standard: The thread of U-bolts should comply with relevant national or industry standards to ensure compatibility with other fasteners such as nuts.
Dimensional tolerance: The dimensional tolerance of U-bolts should be controlled within a certain range to ensure their fitting accuracy with other components.
3、 Application scenarios of U-bolts
Fixed object: Understand what type of object U-bolts will be used to fix, such as pipelines, equipment supports, etc.
This will help determine the required bolt specifications and strength grades.
Environmental conditions: Consider the environmental conditions that U-bolts will be in, such as humidity, corrosion, high temperature, etc.
These factors will affect the material selection and surface treatment requirements of bolts.
4、 Supplier Information
Qualification certification: Select suppliers with relevant qualification certifications, such as ISO 9001 quality management system certification,
to ensure the reliability of product quality and delivery time.
Production experience: understand the production experience and technical strength of suppliers,
including the progressiveness of production equipment, maturity of production process, etc.
This will help evaluate its production capacity and product quality.
Price and Service: Compare prices and services from different suppliers, including product quality, delivery time, after-sales service, etc.
Choose suppliers with high cost-effectiveness for cooperation.
5、 Purchase precautions
Sample testing: Before purchasing, suppliers can be requested to provide samples for testing to verify whether their quality and performance meet the requirements.
Batch procurement: For large-scale procurement, more favorable prices and delivery times can be negotiated with suppliers.
Contract terms: When signing a purchase contract, the specifications, quantity, price, delivery time, quality standards,
and other terms of the product should be clearly stated to ensure that the rights and interests of both parties are protected.
In summary, when purchasing U-bolts, it is necessary to understand their basic specifications,
technical requirements, usage scenarios, supplier information, and purchase precautions. This information will help you make informed purchasing decisions.
