High Strength Galvanized Hex Nut Black Iron Oxide Surface Larger Fastening Force

High-Strength Galvanized Galvanized Hex Nut Chinese standard ( GB ) Black Iron Oxide
 
 
Product Description
 
Hex nuts are bolts or bolts screwed together for fastening parts,An element that must be used in all manufacturing machinery.According to the main attributes of the Chinese standard (GB),German standard (DIN),International Standard (ISO),Japanese standard (JIS),American Standard (ASTM / ANSI)Other standards.The Chinese standard,German standard,Japanese standardWith M said(Eg M8,M16),American Standard,British standard points or # said specifications (such as 8 #,10 #,1 / 4,3 / 8).
 
Hex nuts are components that connect mechanical equipment closely,Thread through the inside,The same size hex nuts and bolts can be connected together,For example, M4-P0.7 hex nuts can only be connected with M4-P0.7 series bolts(M4 hexagonal nut in the hexagonal nut diameter of about 4mm,0.7 refers to the distance between the two thread teeth 0.7mm).American standard products are the same,For example 1 / 4-20 hex nuts can only be used with 1 / 4-20 bolts9(The 1/4 finger hex nut has an inside diameter of about 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.
