Products Description

Hex Jam Nuts are parts that tightly connect mechanical equipment. Through the threads on the inside, nuts and bolts of the same specification can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in the nut Among them, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the same is true for American products, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw ( 1/4 means that the inner diameter of the nut is approximately 0.25 inches, and 20 means that there are 20 teeth in every inch).

Hex Jam nuts is used in conjunction with bolts and screws to connect and fasten parts. Among them, type I hex nuts are the most widely used. Grade C nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; Grade A and B nuts are used for machines with relatively smooth surfaces and high precision requirements. , Equipment or structure. The thickness m of the type II hexagon nut is thicker, and it is mostly used in occasions that often need to be assembled and disassembled. The thickness m of the Hex Jam nuts is relatively thin, and it is mostly used in occasions where the surface space of the connected parts is restricted.

Hex Jam nuts are fasteners that have internal threads and are used in conjunction with bolts, and are mechanical parts that have internal threads and are used in conjunction with screws to transmit motion or power.

Applications:

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.
