Carbon steel hexagonal nut stamped three-point fastener external hexagonal nut nut 4.8 grade locking screw

Product Advantages: The three-point stamp is the manufacturer's public commitment to a nut's performance grade (e.g., Grade 8). It signifies that the nut's mechanical properties, including hardness, tensile strength, proof load, and toughness, have been tested and meet international standards.
Product Selling Point: Nuts bearing the three-point stamp are "equal strength" or "matched strength" nuts specifically designed for use with high-strength bolts. In critical structural connections, they ensure the full strength of the entire joint, avoiding failure modes such as stripping or thread breakage before the bolt due to insufficient nut strength, significantly improving the safety factor of the joint.
Product Applications: Automotive manufacturing and repair: wheel bolt connections, chassis suspension systems, key engine mounting points, and transmissions. Heavy Machinery: construction machinery (excavators, cranes), agricultural machinery, mining equipment, and stamping machines. Rail Transit: high-speed rail and subway car connection structures, rail fastening systems, and bogies. Wind Power: wind turbine tower connections and internal structure connections. Building Steel Structure: main steel structure connections in stadiums, airport terminals, bridges, and high-rise buildings. The product's biggest advantage: The three stamped dots on a carbon steel hexagonal nut (typically spaced 120 degrees apart) aren't just decorative; they're a crucial symbol of quality, performance, and traceability. Carbon steel hexagonal nuts with these three stamped dots essentially promote a "reliable performance guarantee" and a "safe value proposition."
