Product Description

Double - ended studs, or toothed bars, are versatile fasteners used across multiple sectors. Carbon steel double - ended studs are available in different lengths and thread pitches. For example, M12 * 1.75 UNC threaded carbon steel double - ended studs are commonly used in mechanical assemblies.

The quality of double - ended studs is determined by factors such as the grade of carbon steel and the manufacturing process. High - strength carbon steel double - ended studs in grades 10.9 and 12.9 are capable of withstanding heavy loads, making them suitable for industrial machinery and construction equipment.

Surface coatings like zinc plating and black oxide provide additional protection. Zinc - plated white double - ended studs are resistant to rust and have a smooth finish. Black oxide metal bolts, a form of double - ended stud, have improved lubricity, which can be beneficial during installation and disassembly.

Aluminum double - ended studs are also an important part of the fastening portfolio. They are used in applications where electrical conductivity and light weight are important, such as in the aerospace and electrical industries.

Applications
  • Industrial Machinery Assembly: Used to connect heavy-duty components (e.g., gearboxes, engine blocks) in manufacturing equipment, ensuring stable load distribution during operation.
  • Construction Engineering: Secures structural elements like steel beams, columns, and prefabricated panels in buildings, bridges, and infrastructure projects.
  • Automotive & Aerospace: Joins critical parts (e.g., chassis frames, engine mounts, aircraft fuselage sections) where high strength and vibration resistance are required.
  • Power Generation Equipment: Fixes turbine components, generator casings, and transmission systems in thermal, hydro, or wind power plants.
  • Heavy-Duty Furniture & Fixtures: Assembles robust furniture (e.g., industrial workbenches, storage racks) and fixtures (e.g., machine tool bases) needing durable, long-term connections.
Material Specifications
Aluminum Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing.
Titanium EDM machining recommended. Requires deionized water to control heat during processing.
Steel Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management.
Brass High tensile strength, easy to machine but requires slow cutting speed due to softness.
Features & Advantages
  • Dual-threaded design: Enables simultaneous fastening at both ends, simplifying assembly/disassembly of connected parts (e.g., flanges, brackets).
  • Medium carbon steel construction: Offers balanced strength (typically 4.8–12.9 grade) and toughness, suitable for moderate to high-load applications.
  • Reusable & cost-effective: Can be removed and reinstalled multiple times without significant loss of performance, reducing long-term maintenance costs.
  • Gasket-free compatibility: Directly interfaces with mating surfaces or nuts, eliminating the need for additional gaskets while maintaining sealing integrity.
  • High-strength bolt compatibility: Works seamlessly with Class 8.8 and 10.9 high-strength bolts, enhancing overall joint reliability under dynamic or static loads.
  • Durable wholeness: Manufactured with precision threading and surface treatments (e.g., zinc plating, black oxide) for corrosion resistance and extended service life.
