Expansion bolts have the characteristics of free disassembly and assembly in the process of our use, and this small design is convenient for most of us to use and carry, let's take a look at the free disassembly and assembly of expansion bolts.
An expandable stainless steel bolt for free assembly and removal. It is composed of a bolt rod, an expansion tube and a special-shaped cone nut. The bolt rod is successively equipped with an expansion tube and a special-shaped cone nut. Due to the reverse mounting bolt mother.
When the bolt rod is disassembled in reverse, because the expansion tube opening bar and the serrated barb of the special-shaped cone nut edges and corners are interclipped to combine the expansion and the holes as one, the bolt rod is easy to exit, and the next time the bolt rod is inserted, the reinforcement function can be restored.
Stainless steel bolt technical features :1, bolt rod can be equipped with bolt grain T bolt rod, hook head bolt rod, ring head bolt rod according to the demand.
2. The expansion tube is designed as three or four opening bars at one end of the expansion tube, and there are serrated barbs on both sides of the opening bars.
3. Special-shaped cone nuts are designed as trigonal cone bolts and quadrangular cone bolts, and the edges and corners of the bolt mothers are designed with serrated barbs.
(1) Make furniture, ceiling, reinforcement and other construction, you can expand the tube
(2) with special-shaped taper stainless steel nuts
(3) Connect as a whole, put it into the hole, with the bolt rod fastening can be more economical and practical.
