Good quality blind nuts which are at a fraction of the cost my LHS sells them for, plus you get more ( 10 pieces ). I usually purchase items from the Hobby King ( HK ) International warehouse ( Hong Kong ) which I am unable to get from my local HK warehouse, or if it's more cost effective, and this item was one of them. I received my package of items in only 10-days with low cost but reliable Swiss Post Direct Channel shipping, also which included excellent package tracking.

Unfortunately these 4 x 40's are of questionable quality.
Several I have used are an "extremely" loose fit on the associated 4 x 40 hex head bolts and in fact, some almost slide right through the blind nut.
These are called blind nuts for an obvious reason, they are used in areas that are in the main, difficult to access once in position.
For this reason alone they "need" to be of better quality and more consistent in manufacture, as once in position you don't need the added concern as to "when is it going to fail".
Cheers.
