Brass L-Shaped Bent Pin | Precision CNC Turned Components

The brass L-shaped bent pin is a small formed contact and locating pin used in electrical connectors, switch assemblies, and precision electronic devices. The body is CNC turned to size first — including the knurled grip section and stepped diameters — then precisely bent to the L angle, so the pin seats straight in its bore while the bent leg reaches its mating terminal.

We produce it from ? H59 / C36000 free-cutting brass? for excellent machinability and stable electrical conductivity. Critical dimensions — pin diameter ?? Ø1.0–2.5 mm?, bend angle ?90°?, and leg length — are held to ?±0.03 mm?. Batch-to-batch consistency is controlled through SPC on the turning operation and a dedicated bending fixture, which is the step where cheap pins typically lose accuracy.

Available with tin, nickel, or gold plating depending on contact-resistance and soldering requirements.

H2: Key Features - Turn-then-bend process keeps the straight section truly straight and round - Knurled section improves retention in plastic housings - Free-cutting brass for stable conductivity and smooth plating - Tight tolerance on bend position and angle for automated assembly - Plating options: tin / nickel / gold per your spec

H2: Applications Connector terminals, PCB test points, micro-switch contacts, sensor leads, consumer electronics and small appliance assemblies.
