DIN94 Split Pin Metric Carbon Steel Zinc Plated

Mechanical vibration is one of the leading causes of fastener loosening and equipment breakdown in industrial applications. Engineers need simple, economical and dependable safety locking components to secure rotating or moving joints. DIN94 Split Pin Metric Carbon Steel Zinc Plated is a widely recognized metric cotter pin manufactured in accordance with DIN94 German industrial standard. It is installed by passing the pin body through the aligned pre-drilled holes of shafts, clevis pins or bolt shanks, then manually bending apart the two legs of the pin to lock the assembly permanently. This locking mechanism stops relative movement and prevents nuts and pins from spinning free under cyclic vibration and shock load. Made of low carbon steel wire and finished with zinc electroplating, this split pin delivers dependable anti-corrosion performance for most indoor and mild outdoor working environments, and remains a cost-preferred safety fastener choice for countless OEM and maintenance projects.

Core Product Features

Consistent quality starts with strict raw material screening and stable manufacturing process control. DIN94 Split Pin Metric Carbon Steel Zinc Plated is produced within tight DIN94 dimensional tolerances, ensuring smooth insertion into matching pin holes without jamming or excessive clearance. The wire cutting ends are deburred thoroughly during production; no sharp rough edges remain, which protects mating metal surfaces from scratches, gouges and wear during installation. The electroplated zinc coating adheres uniformly to the steel substrate, resisting minor abrasion and surface oxidation. The base low carbon steel retains excellent ductility. Field technicians can bend the pin legs easily by hand or simple tools, and the pin will not crack or snap under normal bending operations. Every production batch goes through random sampling inspection covering dimension measurement and full visual screening to reject defective items with cracks, kinks or plating defects before packing.

Typical Application Scenarios

Numerous industrial assemblies operate under continuous vibration, impact and dynamic load, which gradually loosens unprotected bolt and pin connections. DIN94 Split Pin Metric Carbon Steel Zinc Plated acts as a passive safety locking part used across automotive auxiliary assemblies, farm agricultural machinery, hydraulic valve and cylinder connections, construction machinery, conveyor systems, lifting equipment and general factory mechanical devices. It is most commonly paired with clevis pins, wheel axles, hinge pins and high-load bolt joints. The split pin locks the position of nuts and pins, eliminating rotational movement and greatly lowering the risk of accidental disassembly. Regular use of this cotter pin reduces unexpected machine downtime, cuts equipment maintenance expense and improves long-term operational safety for your finished products.

FAQ

Q1: What is the working principle of DIN94 split pin?

A: The split pin passes through aligned holes on pin or bolt. After installation, the two legs are bent outward to lock the assembly and stop rotation.

Q2: Can you provide alternative material options besides carbon steel?

A: Yes, we supply A2 304 stainless steel DIN94 split pin for corrosive outdoor, marine or humid environments.

Q3: What kinds of zinc plating options are available?

A: Blue white zinc plating and yellow zinc plating are available for carbon steel DIN94 split pins.

Q4: What documents can you provide with the shipment?

A: We can offer commercial invoice, packing list, and MTC material test certificate on request.
