Stainless Steel GB/T 31.2-1988 Hexagon bolts with split pin hole on shank-reduced shank

Hexagon bolts with split pin hole on shank-reduced shank thread specifications range from M6 to M20, with pitch varying from 1mm to 2.5mm. Fine-shank hexagonal head bolts with holes, due to their unique fine-shank design and holed feature, are widely used in applications requiring precise installation and anti-loosening effects, such as highway and railway bridges, industrial and civil buildings, and heavy-duty machinery and equipment.
 
Product Characteristics

• Head design: Hexagonal head design, easy to use tools such as wrenches to tighten.
• Screw characteristics: Thin rod: The diameter of the screw part is small, suitable for specific installation space requirements. With holes: A split pin hole is made on the screw for installing the split pin to increase the anti-loosening effect of the connection.
• Easy to install and remove: The hexagonal head design allows the bolts to be easily installed and removed using tools such as wrenches and sleeves. This convenience improves work efficiency and reduces labor intensity.

 
Application

• Industrial and civil construction: Because of its precise size and reliable mechanical properties, the thin rod hexagonal head screw with hole bolts are widely used in the connection and fixing of industrial and civil buildings.
• Heavy machinery: such as cranes, excavators and other heavy machinery and equipment, thin rod hexagonal head screw with hole bolts because of its high strength and corrosion resistance, can meet the needs of equipment in harsh environments.
• Road and railway bridge: In the construction of road and railway bridge, the thin rod hexagonal head screw with hole bolt is used for the connection and fixing of bridge structure because of its accurate size and reliable connection performance, to ensure the safety and stability of the bridge.
