Product Description

A square head bolt, or square head screw ‌, is a type of fastener that combines functionality with reliability. Its square head is designed to be engaged by a wrench or a socket, providing a reliable means of fastening. Made from premium stainless steels such as 18 - 8, SUS304, and SUS316 series, these bolts offer long - lasting performance in different conditions. The high - strength grades ensure that they can handle substantial mechanical stress. Available in multiple sizes and finishes, including polished and plain, they can meet the aesthetic and functional requirements of diverse applications. From architectural structures to mechanical equipment, square head bolts are a trusted choice for fastening needs.

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
  • 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.
