Suppose we use one sentence to describe the core function of the carbon steel galvanized flat head cylindrical pin with hole. In that case, it is the dual guarantee of precise positioning and repeatable disassembly and assembly. Its specific core functions are as follows.
Core function details
Hard positioning: high-precision matching of the cylindrical surface with the hole position (tolerance h8/h9), forced alignment of parts, and elimination of assembly offset.
One-button disassembly design: the through-hole design at the tail supports quick extraction by hook or rope, solving the pain point of disassembly of the pin without a hole, and improving maintenance efficiency by more than 50%.
Anti-environmental failure: the galvanized layer provides active electrochemical protection, resists corrosion in humid, weak acid and alkali environments, and increases the service life by 3-5 times.
Anti-operational errors: the flat head structure physically blocks over-insertion to prevent the pin body from getting stuck, while increasing the force surface to improve impact resistance.
Irreplaceability: In terms of disassembly, traditional pins without holes require special tools to be pulled out, while cylindrical pins with holes can be pulled out directly by hand. And cylindrical pins with holes can be installed with limited position, while traditional pins without holes can easily be driven too deep. In terms of cost, stainless steel is expensive, while galvanized carbon steel has the highest cost-effectiveness.
Typical scenarios include: assembly line fixture positioning, replacement of agricultural machinery wearing parts, outdoor equipment maintenance, and other precision positioning fields that require high-frequency disassembly and assembly.
