Connector family and interface
Name the family, contact count, pitch and whether the wire lands in a crimp barrel, a clamp, a stud or a PCB tail. A 6 gauge battery cable connector on a busbar is a different part from a small signal plug.

6 gauge battery cable connector sourcing for a factory quotation
LinkScope Sourcing 43 is an independent sourcing partner. Share the lug or clamp you need, the quantity, the US destination and the week you want it to ship, and we ask factories to quote that same brief. A family photo is not a current rating.
Copper 6 AWG has a conductor area near 13.3 mm2. Annealed copper at that size is about 1.30 ohms per kilometer. A 4 AWG conductor is about 21.2 mm2, and an 8 AWG conductor is about 8.37 mm2. Use those figures to check a datasheet, then ask the factory for the exact stranding, temperature class and voltage of the proposed piece. A 5/16 inch stud is 7.94 mm. An M6 stud is 6 mm and an M8 stud is 8 mm. Write the one you measured.
Request Factory Quotes
Attributes to lock before two quotes can be lined up
Current, voltage and plating
Ask for continuous current at a stated temperature rise, the voltage, and the plating metal plus thickness. Tin is common on battery lugs. Silver can lower contact resistance, but the drawing has to say so.
Keying, sealing and cycles
Record keying, the ingress protection code the drawing claims, and the mating-cycle number with its test method. An IP code copied from a catalog family does not travel to a different mold.
Commercial scope
Quantity, currency, per-piece or whole-order budget, Incoterm, freight and the requested delivery window belong in the same note. Leave the budget blank if you are still comparing.
Start from the connector list or read the procurement brief. TIA cabling references can frame a question. They do not prove the lug in front of you.
One planning note can carry two lines without pretending they are one part. A shelter string is written as 6 AWG on an 8 mm stud with tin requested. A service-cart flag is written as a 6 mm post. Each line keeps its own piece count, US destination and shipment week, and each reply must cite the connector mating cycle method plus the ingress protection code tested on that model. Measurement accuracy and calibration traceability belong to the meter used for a resistance check, not to a badge from this desk. The replies are comparable only after boots and spare nuts are pulled out of the piece price.
Who usually writes the brief
Telecom procurement
Procurement managers and infrastructure sourcing teams collect one connector line for a DC plant, a rectifier bay or a radio shelter, then separate it from optics, licenses and rack hardware.
Field and DC operations
Network engineers and field crews measure the stud, the cable gauge already installed, and the bend space inside the cabinet. That measurement beats a marketing photo of a similar boot.
Quality review
Quality staff ask which document is tied to the exact manufacturer and model: drawing, plating note, and any safety file the destination actually requires. A certificate for a different part stays in the file, not in the comparison.
Questions buyers ask before a factory email goes out
What should I prepare if I do not have a drawing yet?
Write the gauge, the termination style, the stud or barrel size you can measure, the quantity, the destination and the week you need shipment. Mark unknown current and plating as open questions for every factory.
How does supplier matching work here?
We send the same brief to factories that can quote the described connector. You compare their model numbers, exclusions and evidence. We do not claim a factory has been audited, and we do not publish a saved-cost figure.
Can a sample and a bulk quote use different assumptions?
Yes, unless you forbid it. Ask each factory to label sample tooling, bulk tooling, plating lot and the lead time basis separately so a short sample date is not read as the production date.
Should a new lug and a refurbished lug share one price?
No. New hardware starts with a full surface and a warranty that begins with that lot. Refurbished hardware can cover a legacy stud when the original flag is gone, but the reply has to state remaining plating and the warranty text. Keep the two offers in separate columns.
Send the 6 gauge brief
Include specification, quantity, destination and requested timing. A target budget can be per piece or for the whole order, with the currency named. Supplier level is your preference, not a score we have checked.
