Split Pins

Split Pins come in several common materials, each picked based on where they’ll be used and what conditions they need to stand up to. The most widely used one is carbon steel—this material is affordable and gets the job done for regular indoor applications, like securing small mechanical parts in machinery that stays in dry, controlled environments. Since plain carbon steel can rust over time if exposed to moisture, it’s usually coated with a thin layer of zinc to add basic rust protection, making it suitable for most everyday mechanical jobs.

Stainless steel is another common choice, especially for outdoor, marine, or humid settings. Unlike regular carbon steel, stainless steel doesn’t rust easily, so it’s a good fit for equipment that’s out in the rain, near saltwater, or used in damp workshops—things like boat engines, outdoor power tools, or agricultural machinery parts. It’s a bit more expensive than carbon steel, but it lasts longer in harsh, wet conditions.

Stainless steel is another common choice， though it’s less common. It’s mainly used in electrical equipment or applications where conductivity matters, as brass conducts electricity well. It also has good corrosion resistance and a smooth surface, which makes it ideal for securing small components in electrical boxes or precision instruments where metal contact needs to be reliable without causing damage. All these materials are chosen for practicality, no extra frills—just to make sure the pin holds up and works as it should in your specific use case.

The shipping cost for Split Pins mainly depends on three things: how much you order, where you need them delivered, and the shipping method you choose. For small orders, we usually calculate the fee by weight—air freight is quicker but costs more, starting around $5-7 per kg for urgent needs, while standard postal or courier services are cheaper for non-rush shipments. For bulk orders, the shipping cost per kg goes down, often starting from $0.84 per kg with a minimum weight requirement of around 50kg. We mostly use sea freight or ground transportation for these big orders to keep costs low. All international shipments include customs clearance fees in the quote, so there are no surprise charges later. They are packed in plastic bags inside cardboard boxes, and large batches go into pallets to save space during shipping—which also helps lower the freight cost. Just let us know your order quantity and destination when you inquire, and we’ll give you a clear, detailed shipping quote. No extra steps or hidden fees, just straightforward pricing based on your actual needs.

What is the correct installation method for Split Pins to ensure secure fastening?

A:It is simple but requires proper operation to ensure safety. First, thread it through the aligned holes on the bolts and connecting parts.Then, Use pliers to bend both ends outward at a 45-60 degree angle—make sure the two ends are bent in opposite directions to prevent the cotter pin from coming off. Do not bend the ends too tightly or too loosely; tight bending may break the pin, while loose bending may cause it to come loose due to vibration. After installation, check that theyare firmly fixed and that the connected parts do not move freely.
