Non-standard stud bolts: a customized tool for precise connection

Double Headed Selfapping Screw

In the field of mechanical equipment and industrial assembly, some key components require fasteners with high strength, precise dimensions and adaptability to specific working environments. Standard bolts cannot meet these stringent requirements in some scenarios, and non-standard stud bolts, with their customized design and versatility, are the ideal solution to meet special needs.

What are non-standard stud bolts?

Non-standard stud bolts are fasteners designed according to specific needs, with threads at both ends and a bare rod or full thread structure in the middle. This type of bolt is usually used in scenarios where double-end fixing or connection is required, such as high-pressure equipment, pipeline flange connections, and core component assembly of large industrial machinery.

Unlike standard stud bolts, non-standard stud bolts are completely tailored to customer needs in terms of materials, sizes, thread forms and surface treatments to meet higher performance requirements.

Features of non-standard stud bolts

Customized size

Non-standard stud bolts can be precisely customized in length, diameter and thread distribution according to the use environment to ensure perfect fit with the equipment.

Length: According to the specific requirements of the assembly location, the length can be accurate to the millimeter level.

Diameter: A larger diameter can be selected to increase the tensile strength, suitable for high-load scenarios.

Material diversity

High-temperature resistant materials: such as chromium-molybdenum alloy steel or nickel-based alloys, suitable for high-temperature environments.

Corrosion-resistant materials: stainless steel or special alloys, used in chemical or marine engineering fields.

High-strength materials: carbon steel or alloy steel after heat treatment, used in scenarios with high dynamic loads.

Optional thread form

Non-standard stud bolts can be designed as single-end coarse threads, double-end fine threads or other special threads to ensure the best tightening effect in specific assembly environments.

Refined surface treatment

Anti-corrosion coating: galvanized, Dacromet or hot-dip galvanized, used in outdoor or humid environments.

Anti-loosening treatment: thread locking glue coating or knurling design to ensure stability during long-term use.

Typical application scenarios

High-pressure flange connection

In the fixing of high-pressure pipelines or container flanges, non-standard stud bolts ensure the sealing and safety of the connection through precise dimensions and high-strength materials. , highlight the key points, and must not be comprehensive; be inspiring and appealing.

Fixing of core components of industrial equipment

In large-scale mechanical equipment, non-standard stud bolts are used to fix key components such as engines, transmissions and supporting structures, providing stability and high load capacity.

Maintenance and modification of special equipment

Non-standard stud bolts are widely used in equipment upgrade or maintenance projects, especially when the original equipment requires special specifications of fasteners to adapt to the modification.

Nuclear and wind power equipment

In nuclear and wind power equipment, non-standard stud bolts are used to fix complex components due to their high strength and durability, and can withstand the test of extreme environments.

Production process and quality control

Material preparation

Select the appropriate material according to the design requirements and cut it into precise lengths.

CNC machining

Process the threads and intermediate polished rods through lathes or CNC machining equipment to ensure that each part meets the design requirements.

Heat treatment

Quench and temper the bolts to improve hardness, strength and wear resistance.

Surface treatment

Perform anti-corrosion treatment such as galvanizing, phosphating or Dacromet treatment to improve the durability and environmental resistance of the bolts.

Quality inspection

Use professional inspection equipment to test thread accuracy, dimensional tolerance and mechanical properties to ensure that the product meets the drawings and customer requirements.
