Carbon Steel ASME/ANSI B18.6.3-30-2013 6-Lobe socket concave large hex head screws-Table 30
Product Overview:
ASME/ANSI B18.6.3-30-2013 Lobe socket concave large hex head screws are a professional-grade, high-performance fastener. In the structural features, a unique six-lobe groove (plum groove) design is adopted, providing higher torque transmission capability and enhancing tool adaptability and ease of use. The concave head design ensures that the tool is firmly held during installation, avoiding slippage and damage. The large hex head makes it easy to use tools such as wrenches or pliers for tightening or loosening, which greatly improves work efficiency. Widely used in machinery manufacturing, aerospace, automobile manufacturing, and other fields.

4.8, 6.8, 8.8, 10.9, 12.9
Carbon Steel ASME/ANSI B18.6.3-30-2013 6-Lobe socket concave large hex head screws-Table 30 Details
Technical specifications
Thread size: 4# inch to 1/4 inch
Material: Carbon Steel
Surface treatment: galvanizing, black oxide, Dacromet, etc
Product Overview
ASME/ANSI B18.6.3-30-2013 Lobe socket concave large hex head screws have the unique six-lobe groove (plum groove) design, providing higher torque transmission capability and enhancing tool adaptability and ease of use. Widely used in applications requiring high torque transfer and anti-loosening, its unique quince-shaped groove design facilitates tightening with specific tools, while the concave brain design increases head strength for heavy-duty applications.
Main functions and advantages
Unique plum groove design: The head of the screw adopts a six-lobe plum groove design, which not only increases the torque transmission ability of the screw but also improves the anti-slip performance of the screw, making the screw more stable and reliable during tightening.
Concave head structure: The concave head design of the screw head helps to better accommodate and secure the tightening tool during the tightening process, preventing the tool from slipping or damaging the screw head.
Large hex head: The screw head adopts a large hexagonal design, which is easy to use with tools such as wrenches or pliers for tightening operations, improving work efficiency.
Fine thread: Screw with fine thread design, this thread has better sealing and fastening force, suitable for high fastening requirements of the occasion.
Application
Machinery manufacturing: Used for the fastening connection of various mechanical equipment, such as automobiles, aircraft, ships, and other vehicles, in the manufacturing process.
Construction engineering: Used for steel structures, bridges, building curtain walls, and other fields of fastening connections, to ensure the stability and safety of buildings.
Electronic equipment: used for the assembly and fixing of electronic products, such as the connection of internal components of computers, mobile phones, and other devices.
Aerospace: Used for fastening and connecting aerospace equipment to ensure stability and reliability in extreme environments.
Thread size: 4# inch to 1/4 inch
