Tell you a few better, depending on your batch is not big.
If large, 1, you can find zhejiang jinyi industry, this in the country and the whole world are famous, his products are relatively expensive, but the quality is particularly stable, his subordinate has a subsidiary specializing in automotive standard parts, the quality of the problem. 2, you can find ningbo donggang, his 10.9 bolts are also very good, the quality and price is more appropriate, and now in the country, the quality is very good. 3, shanghai haha, the fastener industry is the largest, the fastener industry is the largest. Comparison of good. 3, Shanghai Hardiway, this manufacturer directly to the public to provide standard parts, the price is relatively cheap, the quality is also OK, than the last 2 scale and quality to be worse than the point. 3, there are Ningli, cheaper, quality is general. 4, Jiulong standard parts, the quality of the general price is OK.
There are many manufacturers on the market to do, but used in the car above, I suggest to use the quality is more stable, if there is a problem, it is not good to deal with. There are many trading companies on the market, they do not produce at all, but also said that the production, in fact, are outsourced processing, you have to look carefully, be careful to be fooled Oh.
