What Are Self-clinching Blind Fasteners Blind Press Nuts?
The self-clinching blind fastener is also called type B self-clinching blind nut or self-clinching blind press nut.
This type B self-clinching blind fastener is a nut with an internal thread with a blind hole. The head end is similar to the S-type pressure riveting nut, which forms an effective internal thread on the plate.
This self-clinching standoff blind nut is used where the bottom needs to be closed. The closed bottom can limit screw penetration and isolate the external environment.
The self-clinching blind press nut type B is produced by an automatic lathe, which is completed by bar turning, punching, embossing, and tapping at one time. Type B blind press nuts are available in two materials, one is carbon steel and the other is stainless steel.
The self-clinching blind fastener is divided into B type and BS type, B type is carbon, BS is stainless steel
BS stainless steel sealing self-clinching blind fastener
Material: SUS303, SUS304
BS stainless steel sealing studs are not heat-treated, and the hardness is HV190-250
Surface treatment: BS-default is stainless steel
The stainless steel type self-clinching blind fastener is made of SUS303 or 304. It should be used in rust-proof workplaces such as aluminum and copper plates. It has a sealing and waterproof effect. It is not recommended to be used for stainless steel plates (although it can be used)
The self-clinching blind fastener press nut has an internal thread with a blind hole, and the head end is similar to an S-type pressure riveting nut, which forms an effective internal thread on the plate.
Type B self-clinching blind fastener
Used in the working environment where the bottom end needs to be closed, sometimes called waterproof stud or waterproof nut column
The specific material: Type B-1215 or 10B21
Hardness: B-type self-clinching blind fastener is carburized to HV400-500 (using 1215 material) or HRC28-38 (using 10B21 material)
Surface treatment: B-default is blue and white zinc

How to install the self-clinching blind nuets?
The installation method of the self-clinching blind fastener combines the characteristics of the installation of the pressure riveting nut and the installation of the pressure riveting stud, and the installation is simpler.
Self-clinching blind fastener press nuts provide load-bearing threads on thin plates and are suitable for aluminum, cold-rolled steel, and other tough materials. The hardness of the carbon steel sheet shall not exceed HRB70, and the sheet shall not be heat treated; the hardness of the stainless steel sheet shall not exceed HRV80
The self-clinching blind fastener blind press nut overcomes the problem that the mounting plate is too thin and cannot be tapped and fully meets the requirements of production and fastening.
The installation of the self-clinching blind fastener press nut is simple, fast, and convenient. You only need to place the nut in the pre-punched or drilled installation hole, apply a certain installation force, and easily insert the product into the installation plate.
The fastening ring of the self-clinching blind fastener is tightly meshed with the metal plate to ensure that the product has a strong push-out resistance. The combination of knurling and metal plate gives the product a higher torsion resistance.
It is recommended that the shank length of the product is always less than the minimum thickness of the mounting plate, and the inner thread of the nut will neither be deformed nor easily damaged under the condition of applying proper installation force. Complete the product installation from the mounting surface of the mounting plate, and keep the back of the mounting plate flat and smooth.
