GB Galvanized Hex Nut Iron Galvanized Various Specifications / Various Colors
Product Description
Hex nuts are parts that are screwed together with bolts or screws for fastening, all of which must be used to make a machine. According to the property, it mainly has such standards as GB, DIN, ISO, JIS, ASTM / ANSI. The Chinese standard, German standard, Japanese standard with M that (such as M8, M16) American Standard, the British standard points or # said specifications (such as 8 #, 10 #, 1 / 4,3 / 8).
Hex nuts and bolts, screws used in conjunction, play the role of fastening fasteners. One of the most widely used type 1 hex nut, C-level nuts for the surface roughness, less demanding on the accuracy of the machine, equipment or structure; A and B-level nuts for the surface more smooth, high precision machines , Equipment or structure. Type 2 hexagonal nut thickness m thick, often used for the often need to dismantle the occasion. Thin hexagonal thin nut thickness m, and more for the surface area of the connected parts is limited by the occasion.
Hexagon nut is the part that connects the mechanical equipment tightly. Through the inner thread, the same size hexagon nut and bolt can be connected together. For example, the hex nut of M4-P0.7 can only be connected with the bolt of M4-P0.7 series (In the hexagonal nut M4 refers to the hexagonal nut diameter of about 4mm, 0.7 refers to the distance between the two thread teeth 0.7mm0.7). The same applies to American Standard products, for example, 1 / 4-20 hex nuts can only be fitted with 1 / 4-20 bolts (1/4-inch hex nuts have an approximate inner diameter of 0.25 inches and 20 means 20 teeth per inch) .

Features
Wide range of applications, characterized by a larger fastening force, the disadvantage is that there must be sufficient space for installation, the installation can be used to live wrenches, open-end wrenches or glasses wrenches, the above wrenches require a lot of space for operation.
Applications
Automotive industry, machinery manufacturing, pneumatic tools, furniture hardware, construction and so on.
