Joywayus Internal Hex Head Socket Pipe plug M8x1 Thread Stainless Steel Pipe Fitting Rods By CNC

Used them all work perfect

Perfect everything perfect

Worked as expected on my BorgWarner EFR turbo. If you round the allen head, this can be used as a replacement.

I bought this for my Genuine G400c motorcycle. A crankcase plug that is made out of plastic was cracked and thus the bike was leaking. I ordered this while the replacement arrives but I think I will leave it there. It is not shown but it comes with the bronze washers. Hex hole is a tight fit as it should be. I’m very happy with this product.

Worked for my project.

I bought this to replace the plastic plug on my 2004 Aprilia Tuono R. For those wondering, this will fit any Aprilia with the Rotax V990 motor and indeed any other motorcycle with that engine, like the KTM Duke 990, while preserving the original look of the stator cover. The plastic plug is weak and cracks quickly, but is not easy to replace when it does.There was a dent in one of the threads, perhaps from impact during shipping. The hex socket appears to be just slightly off center, but it threaded into the inspection port on my bike and seated well. There was some resistance from the damaged threads but it was not enough to cause alarm, or make me fear that the threads on the stator cover would be damaged. It includes a copper washer which I believe is not mentioned in the listing. Overall a pretty good product.

Fit perfect, comes with 2 brass washers different thickness.

Chinese garbage. Doesn't have a chamfer and will strip out your threads if you're not careful. The washers that it came with were also too small. What a joke and waste of money

Very good quality plug. Well built and looks nice.
