Natural Chinese Standards Of Various Models Galvanized Hex Nut Iron Galvanized
Product Description
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) .

Applications
Automotive industry, machinery manufacturing, pneumatic tools,
furniture hardware, construction and so on.
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.
