Types, specifications, uses and methods of use of embedded expansion nuts
The embedded expansion nut is mainly used for the fastening of components in construction, hardware and decoration operations. The nut includes a nut body and a taper pin. Its types and specifications are:
1. Low-carbon steel expansion nuts: specifications include M6~M20, which are used for general purposes.
Second, stainless steel expansion nut: specifications include M12~M20, used in places where corrosion resistance is required.
3. Nylon expansion nut: specifications include M3~M6, used in places where the resistance to tension is not high.
Four. Insulation expansion nuts: specifications include M6~M12, used in places where electrical insulation is required.
The use and method of embedded expansion nut: (Guide: Stainless steel bolt strength grade, stainless steel bolt type)
The embedded expansion nut is a special nut similar to the expansion bolt. It is composed of two parts, a circular tubular nut and a pile pin. With hexagonal bolts, flat washers and spring washers, it is used to fix the machine parts on the concrete base or wall. When using, first use a percussion drill or hammer to drill the foundation, and then put the nut and pile pin into the drilled hole, and hammer the pile pin with a hand and a special mandrel to make the low end of the pile pin and the nut lower The ends are flush, so that the bottom of the nut expands around and is firmly fixed in the foundation, then align the mounting holes on the several pieces with the nut holes, put flat washers and spring washers in turn, screw in the hexagonal head bolts to make the machine parts It is firmly fixed to the foundation.
The above is the relevant information of the embedded expansion nut. If you are still worried about the types, specifications and usage of the relevant fasteners, after you read it, I believe you will make the right choice.
