A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.
Ningbo Weifeng Fastener Co., Ltd., established in the year 2003, is a global industry and trade combined company. Our company is specialized in developing, manufacturing, trading and providing services for fasteners and hardware tools.
