What YourSpec Offers

Quality materials

We only stock high quality wire, pins, and connectors. We understand every project has different needs, so we make sure to stock wire with multiple options of strength, weight, and durability so your project gets exactly what it needs.

Cut to length

Order individual wires accurately cut to length for your project, but pay like you bought in bulk. We have redundant systems in place to make sure your wire is cut to your exact specification.

Wire marking

Our wire marking system incorporates a state of the art UV laser that reacts photochemically with the titanium dioxide (TiO2) in the wire insulation. This results in a highly durable and readable marking.

end stripping

Stripping with YourSpec guarantees precise cuts every time. We use high end rotary stripping tools that can accurately measure and strip your wire to exact measurements. Our tools have an integrated sensor to detect blade contact with the conductor.

crimping

Save time in assembly time by allowing YourSpec to do the crimping for you. We have a variety of tools and die-sets specific for each pin we offer.

Tinning

Want to add a bit of robustness to the end of your wire or are using screw down terminal blocks? Specify tinning on your wire ends for the prefect solder coverage.

full control

Our Wiring Project Manager allows all processing options to be fully configurable to ensure our services can be used in all varieties of projects.
