I've got a case of 4 screw/4-pin (m4 sized screws) terminals. The terminals and pins themselves are gold plated, however the screws are nickel plated, so the price has been adjusted accordingly. If you're wanting gold plated screws for these terminals, contact me and we can hammer out the finer details on your order. These fit a lot of old school car audio amplifiers. The front body of the terminals measures 45mm across. Including brackets on the backside of it is 61.5mm across and if the brackets were omitted the backside measures 47.5mm. the depth from PCB pins to the front of the terminal is 23.5mm and the height not including the pins is 16mm, with the pins it's 22mm. It is your responsibility to ensure fit or message with any question on the dimensions. I put the terminal up next to an old Sony amp for comparison and the terminals are the same size. The amp is for comparison only and is not part of the sale. All sales are final and the items are brand new and have never been mounted. Thank you for looking. I have 8-pin terminals and gold plated screws also for sale, check out my other posts
