Hello, I am in need of an extra nut '07119905544'.

View post on imgur.com

It's nothing emergency so i can order from FCPeuro but i was hoping to see if i can pick it up from Autozone or O'Riley to avoid extra time and cost in shipping.

Does anyone know an equilavent size for this particular nut? I tried on Amazon and Autozone for M6 8mm nut but i couldn't find one that looks like '07119905544' which has a plate on one side (bottom) of it.

If you have one near you, try a local hardware store. Not one of the big box ones. They usually have a full aisle of individual fasteners and someone to help you find the right one.

Thanks Strada. I will visit a Ace Hardware tomorrow and try my luck

They'll figure out something to get you by!

Try looking for a flange nut:

Where's it going? Might not matter for something this small but doesn't hurt to verify the required grade (eg Home Depot Motorsports is 5.8 and you may need 8.8)

Hello, thank you for the link

It's to the 'section hose' near by the secondary air pump

To paraphrase Dr. Freud, sometimes a nut is just a nut.

There's no reason why any properly sized flange nut from the hardware store wouldn't fix you up right good in this case.

As others have observed, the "flat plate" on a nut/bolt is called a "Flange" Nut/Bolt. If one is missing, and you have a splash shield in place under the engine, nut is on splash shield (IF you are lucky ;-)

If you want to DIY on cars built in last 35 years, most bolts and nuts are Metric as opposed to SAE, and RealOEM.com says that nut is M6:

You can find a replacement at any Home Depot, NAPA, etc. OR, you can get a KIT of metric flange bolts and metric flange nuts. Here are some Amazon choices:

This is great. Thank you very much George

OP, some helpful info. If you are going to work on cars it is best to understand fasteners. The Boltdepot is great resource for learning about fasteners (I learned in engineering school however). https://www.boltdepot.com/fastener-i...n/Default.aspx

But the basics are: fasteners come in basically two versions "SAE" and "Metric". SAE is just a fancy term for Society of Automotive Engineers. SAE is otherwise known as "Standard" or "American" thread fasteners. SAE was originally an American institution (a body of American automotive engineers). Metric is exactly that, metric-sized fasteners, used worldwide outside the USA.

A thread size is defined by the screw/bolt diameter (in inches or millimeters) and the thread pitch/count. SAE fasteners use a thread count and Metric use a thread pitch. A lot of people get thread pitch and thread count confused. Pitch is the distance in millimeters between the treads. Count is the number of threads per inch. There are basically two thread specifications "course" and "fine". Fine threads use more threads per given length of fastener. Most thread descriptions are depicted commonly as "course" rather than "fine". Fine threads are usually used for special applications; course threads are most commonly used for most fastening applications. Fine thread provides more holding power because there is more thread surface area per given fastener length. This is important for small diameter bolt/screws where because of the smaller diameter of the bolt shaft, lower torque values must be used (or the shaft breaks), so more threads per length provide more thread surface area, this more friction per given distance, thus more holding power. Theads hold tension because of the mating surface area between the bolt and nut threads. That's how threads work, surface tension via friction between the (thread) surfaces*.

So, for your p/n, it is an M6 nut (metric - 6MM). The specification for metric course pitch for an M6 thread is 1 MM, meaning the distance between each thread peak (i.e. top of the thread) is 1 millimeter.

Such information helps when searching at the hardware store for fasteners. Ill-informed folks need to use the placards on the wall with the embedded nuts or bolt thread studs.

* which gets back to other recent posts about cleaning the OPG thread (holes). Having oil in the thread holes lowers the coefficient of friction between the thread surfaces, which affects the torque values. That means to set the correct torque you have to over torque the bolt, which will snap the aluminum bolts used for the oil pan.

One additional bit of helpful information - metric nuts and bolts are measured by the threaded part, not the head. So a M6 bolt is 6mm across the threaded body, the head size can vary, though *usually* will be 10mm.

Generally, if you can't find the right flange nut, a regular nut and a washer is a perfectly fine substitute. The flange is mainly to provide added friction/spread clamping force and to make assembly easier.

And if you are really fussy, you can just buy the nuts and bolts at the dealer.

Nerd Alert II !
Since bolts/ studs/ nuts do NOT have size & pitch etched on them, a REAL DIY'er or Engineer will have Tap & Die set to MEASURE threads, as well as having properly-organized nuts & bolts, Metric & SAE, on hand. Here are some examples:

I just use cheapest I can find.

Hi everyone, thank you very much for all the information.

I am a bit confused on the oem/oe nut (07119905544) I provided. For this nut, I noticed this supplier number 'M6-8-ZNNIV SI'.

Does anyone know what the '8' stands for? This was really throwing me off lol.

8 is the property class proof load rating for the nut. ZNNIV means it is zinc plated. Again "M6" means it's Metric and the thread size is 6MM. 6MM thread is standard course thread w/1.0MM pitch.

It's not holding a critical part. Just get an M6 nut, 6MM washer and a lock washer, zinc plated if you can from an auto parts store or a hardware store and call it a day. You are way over thinking this. Friendly advice...

id just hit my local ace, test fit the size and pocket it.

hope this helps
