Product Description
Cylindrical head hex socket screws, also known as hex socket bolts, cup head screws, and hex socket screws, have different names but represent the same meaning. For the commonly used hex socket cylindrical head screws, there are grades 4.8, 8.8, 10.9 and 12.9. It is also called an Allen screw or an Allen bolt. Its head is an inner hexagonal head and also a cylindrical head.
Material Classification
  • Stainless steel SUS202 hex socket cylindrical head screws (common stainless steel)
  • Stainless steel SUS304 hex socket cylindrical head screws
  • Stainless steel SUS316 hex socket cylindrical head screws
Strength Grades
  • 4.8 grade hex socket cylindrical head screws
  • 8.8 grade hex socket cylindrical head screws
  • 10.9 grade hex socket cylindrical head screws
  • 12.9 grade hex socket cylindrical head screws
Hex socket cylindrical head screws of grade 8.8-12.9 are called high-strength and high-grade hex socket bolts.
Applications
The application range of bolts is extensive, including electronic products, mechanical products, digital products, power equipment, and mechanical and electrical machinery products. Bolts are also used in ships, vehicles, hydraulic projects, and chemical experiments. They are used in many applications from miniature bolts for precision equipment to large bolts for construction projects.
Industry Usage
Automotive In high-strength applications such as automotive engines, heavy-duty machinery, and bridge construction
Mechanical Used to connect various mechanical parts, circuit boards, engines, transmissions, building structures
Energy For connecting power generation equipment and transmission lines
Architectural In construction engineering, shipbuilding, and petrochemical industry
Material Specifications
Material Properties
Aluminum Excellent thermal and electrical conductivity but naturally soft
Titanium EDM machining is well suited for titanium as the process can withstand the viscosity
Steel Very strong metal that generates significant heat during processing
Brass High tensile strength and easy to machine, but requires slow cutting speed
Feature Advantages
Ordinary bolt heads are very thick and difficult to deform. If vibration occurs, they may need re-tightening. Flange bolts with thinner parts can slightly deform, allowing for more secure locking.
Flange bolts offer additional advantages:
  • Can be used with special tools in confined spaces
  • Flange plate provides additional fastening support
  • Safer for use with softer, non-wear-resistant materials as they prevent perforation
