1、 Product Details
1. Waterproof nuts are divided into B type and BS type.
2. The B-type material is carbon steel, and the default surface treatment is blue white zinc.
3. The BS type material is stainless steel, and the surface treatment defaults to stainless steel natural passivation treatment. Made by forging SS304 or 303, it is used in rust proof work environments and has a sealing and waterproof effect.
2、 Attention:
1. Requirements for the board:
The hardness of carbon steel sheets should not exceed HRB70 °. Thin sheets cannot be subjected to heat treatment; The hardness of stainless steel plate shall not exceed HRV80 °.
2. Adaptation of Waterproof Nut and Board Material
(1) Type B corresponds to carbon steel thin plates.
(2) BS type corresponds to aluminum and copper plates, and it is not recommended to press stainless steel plates.
3、 Working principle of rivet nut
Waterproof rivet nut, also known as sealed rivet nut column or waterproof nut column, has a blind hole internal thread, and the head end is equivalent to an S-shaped rivet nut, which is riveted to the plate to form an effective internal nut. The blind hole design of waterproof rivet nuts can effectively prevent external substances from entering, and the rod of the product can be used as a positioning rod for installing other parts. The installation method combines the characteristics of rivet nut installation and rivet bolt installation, and waterproof rivet nuts are used in working environments that require closed bottom ends.
