This flat head brass split pin — also widely known as a brass insert pin, brass dowel pin, slotted cotter pin or brass locating pin — is precision CNC machined from premium brass raw material. Featuring a unique slotted split spring structure and flat head design, it is produced through turning, grooving and cutting processes.

The brass split dowel pin delivers stable elastic clamping force, excellent ductility, wear resistance and corrosion resistance. These copper insert pins are commonly used for locating, connecting, fastening and anti-loosening locking in mechanical assemblies. SITUOWUJIN supports full non-standard customization of brass split pins, brass locating dowel pins and slotted brass insert pins based on your drawings or samples to meet diversified assembly demands.

• Raw Material: High-quality brass — rust and corrosion resistant, with outstanding ductility and stable spring elasticity.
• Optimized Structure: Flat head plus slotted split design makes this brass cotter locating pin easy to insert and install, locking firmly in place.
• Precision Machining: CNC turning and slotting cutting deliver tight dimensional tolerances and a smooth, burr-free surface.
• Anti-Loosening Performance: The split slotted spring pin structure creates consistent elastic clamping, so the brass dowel pin will not detach easily after assembly.
• Versatile Usage: Ideal for applications requiring repeated disassembly, positioning and locking.
• Flexible Customization: OEM & ODM service available. We custom-make brass locating pins and slotted copper insert pins in different outer diameters, lengths, slot widths and head sizes.
