DIN934/439 ASTM A194/563 carbon steel Hot dip galvanized / HDG Hex Nuts For electric tower

1. Product Description

Hot-dip galvanizing of nuts is an effective way of metal corrosion protection. It immerses the nuts after rusting into the molten zinc solution at about 500 C, so that the surface of nuts adheres to zinc layer, thus playing a role of corrosion protection. Because the hot dip galvanized coating is thicker (generally more than 40um), considering its effect on thread accuracy, the pore size of hot dip galvanized nuts should be slightly enlarged than that of ordinary nuts. The specific requirements are as follows: the product type of British metric pore size enlarged mm<7/16>7/16 M10-M14 M16-M20 M24 M27 M30 0.41 0.53_0.3. 5 0.40 0.45 0.50 0.55 2. The upper limit of contralateral and thickness control dimension is increased by 0.5mm compared with the upper limit of specification. A kind of
The production process of hot dip galvanizing mainly includes: original plate preparation pre-plating treatment hot dip plating post-plating treatment finished product inspection, etc.

3. Application

1, the common six corners outside the world -- widely used, characterized by relatively large fastening force. The drawback is that there must be enough space for operation when installing. When installing, you can use live wrenches, open wrenches or glasses wrenches. The spanner needs large space for operation.

2, the cylinder head inside hexagonal-is the most widely used of all screws, because it is relatively large fastening force, the use of hexagonal wrench can be operated, easy to install, almost all kinds of structures. The appearance is more beautiful and neat, the disadvantage is that the fastening force is slightly lower than the outer hexagon, and it is easy to damage the inner hexagon after repeated use.

3, inside the disk head hexagonal-rarely used mechanically, mechanical performance is above, mostly used in furniture, the main role is to increase contact with wooden materials and increase the appearance of the ornamental.

4, a headless six angle - some structures must be used, such as a top wire that requires a large top force, or a place where a cylindrical head needs to be hidden.

5. Hex of countersunk head-mostly used in power machinery, the main action is the same as the inner hexagonal.

Nylon lock nut-insert nylon rubber ring in hexagonal plane to prevent thread loosening structure, strong power mechanical use.

7, flange nut - mainly to increase the effect of contact with the workpiece, mostly used in pipes, fasteners have some stamping parts and casting parts.

Ordinary hexagonal nuts-most widely used, but also one of the most common fasteners.
