Product Details
Type 1 nut refers to a regular hexagonal nut with a nominal height m ≥ 0.8D, and its type and size should comply with the provisions of GB/T6170; The height of type 2 nuts is higher than that of type 1 nuts, and their dimensions should comply with GB/T6175. The purpose of adding Type 2 nuts is twofold: firstly, to obtain a relatively inexpensive nut that does not require heat treatment by increasing the height of the nut. Because grade 8 type 1 nuts with D ≤ M16 do not require heat treatment, only grade 8 nuts with D>M16-39 specifications use type 2 nuts. Obviously, type 1 nuts without heat treatment cannot meet the mechanical performance requirements of grade 9 nuts. Another purpose of specifying Type 2 nuts is to obtain Grade 12 nuts with better toughness. Due to the increase in height of the nut, the guaranteed stress index can be achieved at a lower quenching and tempering hardness, thus increasing the toughness of the nut. Classified by tooth pitch: standard teeth, regular teeth, fine teeth, extremely fine teeth, and cross teeth. Classified by material: stainless steel hex nuts and carbon steel hex nuts, copper hex nuts, and iron hex nuts. Classification by thickness: hexagonal thick nuts and hexagonal thin nuts. Classification by usage: hot-melt copper nuts, hot-press copper nuts, embedded copper nuts, and ultrasonic copper nuts
The DISC-LOCK jam nut is composed of two parts, each with alternating cams. Due to the internal wedge design slope angle being greater than the nut angle of the bolt, this combination tightly bites into a whole. When vibration occurs, the protruding parts of the DISC-LOCK jam nut move together, generating lifting tension, and achieving perfect anti loosening effect.
In general, electroplating of combination screws refers to the electroplating of iron combination screws. Electroplating can be divided into environmentally friendly and non environmentally friendly. Commonly used combination screw electroplating colors include environmentally friendly color zinc, environmentally friendly blue zinc, environmentally friendly white zinc, environmentally friendly nickel, red color, white zinc, white nickel, etc. The use of cross recessed combination screws, hexagon combination bolts and self tapping combination screws is the same as that of corresponding cross recessed screws, hexagon head bolts and Self-tapping screw. The main feature of these combination screws is that they are all equipped with corresponding washers, which is very convenient to use.
