The range
Every BNC variant we stock
The variants differ on three things: what's plated, how big the barrel is, and how the barrel is knurled. Filter below, or read the comparison further down if you're not sure which one your buyer is asking for.
BNC Semi Gold
Nickel-plated barrel with the collar and centre contact in gold. The volume seller — gold where the current flows, nickel where it doesn't.
BNC Full Gold
Gold plating across the whole body, collar and contact. Uniform finish end to end, and the one customers pick when the connector is visible on the set.
BNC Dotted
Diamond knurl cut across the barrel, so the surface reads as dots. Grips well with dry or oily fingers and doesn't slip during a quick swap.
BNC Lining
Straight knurl cut in blocks down the barrel. The ribs are deeper than the dotted pattern, which makes it the easier one to turn with pliers.
BNC Female
The socket half. Nickel body, gold centre pin, side screws for panel fixing. Mates with every male variant on this page, whatever the plating.
BNC Semi Gold — Big Size
The semi gold finish on the longer body, with a wider collar and a deeper knurl. Built for thicker cable and rougher handling on site.
BNC Full Gold — Big Size
Big-size body in full gold plating. Top of the range on both counts, and the variant most often ordered as a matched pair with the female.

We machine and plate to order as well. Send the sample or the drawing and we'll tell you whether it's a stock item, a plating change, or a new tool.

Where they're used
What buyers fit them into
BNC is a bayonet-lock coaxial connector: push, quarter-turn, locked. That lock is why it stayed the standard anywhere a cable gets handled often and must not fall out.
CCTV and video
The bulk of what moves through our counter. Camera to DVR runs, patch leads, and replacement ends for cable already pulled through conduit.
Test and measurement
Oscilloscope leads, signal generators and bench patching, where connectors are mated and unmated dozens of times a day and plating wear shows first.
Panel and rack assembly
The female variant mounts through a panel and takes the male from the front, which is how most enclosure and rack builds terminate a coax run.
Audio and broadcast
Word clock, timecode and digital video links in studio racks, where a locked connector matters more than a fast one.
Repair and service counters
Small counts, mixed variants, bought regularly. We pack in counted boxes for this so your counter staff aren't weighing out loose pieces.
Small-batch manufacturing
Where the same part goes onto a line week after week and the finish has to match the last lot. This is what the per-lot plating check is for.

Before you order
Trade names for these parts are not standardised. Two suppliers can sell different things under the same variant name, so match on the comparison table above rather than the name alone.
If your application depends on an exact dimension, impedance or cable size, ask us in writing and we will confirm it against the lot we would ship you.
For anything outside this list — a different plating spec, or a part made to your own sample — send the sample or the drawing.
Supply
How we ship it
Standard terms for the BNC line. Anything outside this — custom plating, printed boxes, a mixed pallet — ask and we'll price it.
Plating checked per lot
Gold thickness is sampled from every plating lot before it's packed, so the colour and the contact resistance stay consistent across a repeat order.
Packed for the counter
Loose in poly bags for bulk, or in counted boxes if you're selling over a counter. Tell us the count you want per box and we'll pack to it.
Samples before the order
We send a sample set of the variants you're considering, so your workshop can check the fit before you commit to a quantity.
Held in stock
All seven variants are kept on the shelf in standard quantities. Big or mixed orders are confirmed with a dispatch date when we quote.
Ordering
How an order runs
Four steps from first message to dispatch. Most enquiries clear the first two on the same day.
Tell us the variant
Name it from this page, or send a photo of the part you're replacing and we'll identify it. A photo is usually faster than a description.
Get the rate
We come back with a rate for your quantity, the packing option, and a dispatch date. Ask for the full rate list if you buy across variants.
Check a sample
On a first order, or when you're choosing between variants, we send samples so your workshop can check the fit before you commit.
Confirm and dispatch
Confirm the quantity and delivery city. We pack to your count, raise the invoice against your GSTIN, and dispatch.
Questions
Asked before you buy
If your question isn't here, send it on WhatsApp — we'd rather answer it before the order than after.
What's the difference between semi gold and full gold?
Semi gold has a nickel-plated body with the collar and centre contact in gold — gold where the current flows, nickel where it doesn't. Full gold is plated gold across the whole part.
Electrically they behave the same, because the contact surfaces are gold on both. The difference is appearance and cost. Full gold is chosen when the connector is visible on the finished equipment.
What does dotted and lining actually mean?
It's the knurl pattern cut into the barrel — the grip. Dotted is a diamond knurl, so the surface reads as small raised dots. Lining is a straight knurl cut in blocks running down the barrel.
Lining has deeper ribs, which makes it the easier one to turn with pliers. Dotted grips better with bare fingers. Nothing else about the part changes.
Will the male and female halves mate across variants?
Yes. Every male variant on this page mates with the female, regardless of plating or grip pattern. Plating and knurl are finish choices, not fitment changes.
What's the difference between small size and big size?
Big size has a longer barrel and a wider collar. It's specified for thicker cable and for work that gets handled roughly on site, where the extra grip length helps.
If you're replacing an existing part, send us a photo alongside a ruler or a coin and we'll tell you which size you're holding.
Can I order a small quantity, or mix variants in one order?
Yes to both. Counter retailers and repair workshops buy small and mixed all the time. Send the list with counts against each variant and we'll quote the whole thing together.
Do you send samples before a bulk order?
Yes. Tell us which variants you're comparing and we'll send a sample set so your workshop can check the fit first. We'd rather spend a sample than take back a wrong box.
Will a repeat order match the last one?
That's what the per-lot plating check is for. Gold thickness is sampled from every plating lot before packing, which is what keeps colour and contact resistance consistent across repeat orders.
If you're matching against stock you already hold, mention it when you order and we'll check against the same specification.
Do you supply parts that aren't on this page?
Yes. We handle custom plating specifications and parts made to your own sample. Send the sample or the drawing and we'll tell you whether it's a stock item, a plating change, or a new tool.
