General
We manufactured custom brass split pins for an industrial customer in Panama according to the customer’s drawing and assembly requirements.
Project Overview
This project involved the production of custom brass split pins for a Panama customer.
The split pins were used as part of a bolt assembly set, where each set included:
- one bolt
- two thick washers
- two thin washers
- two brass split pins
A total of 60 pieces of brass split pins were produced for the order.
Function of Brass Split Pins
Split pins (also known as cotter pins) are commonly used as locking fasteners in mechanical assemblies.
They are inserted through a hole in a bolt or shaft and then bent outward to prevent the fastener from loosening during operation.
Brass split pins are often used when corrosion resistance and good machinability are required.
Manufacturing Process
The production process included:
- wire folding
- head forging to form the pin head
- dimensional inspection
- packing in plastic bag and box
All sizes were measured and verified before shipment to ensure the parts matched the customer’s specifications.

Quantity
The order included 60 brass split pins for 30 complete bolt assembly sets.
Each assembly set consisted of one bolt, two thick washers, two thin washers, and two brass split pins.

Brass Split Pin Head
Because the pin head was relatively large, it could not be formed into a perfectly round shape by conventional stamping. A slightly square head profile was therefore accepted according to the confirmed manufacturing solution.

Size Inspection
All specified dimensions were measured, and inspection photos were sent to the customer for approval before shipment.
Packing
The finished brass split pins were packed in plastic bags and then placed in cartons together with the related bolt assembly components for export shipment.
