Double Sided Machine & Self Tapping Threaded Colour-Zinc Plated Wood Dowel Screws
Jiaxing Haina has varieties and complete specifications fastener product.Major products are stainless steel and grade 4.8/8.8/10.9 high intensity bolts , hexagon bolts , carriage bolts and all kinds of standard bolts , hexagon socket screws , self tapping screw , self drilling screws , hex nuts , threaded rod , anchor bolts and so on. Our company have many stock of Stainless steel: All DIN Or GB Standard stainless steel Nut.
Â
Application:
Â
The square nuts are generally used in furniture as a blind nut. The thin square nuts are also used in rail channels in order to prevent turning of rail when pressure is applied. They are also used to make perfect foundation in metal channels for hidden fasteners.
Â
Advantages:
1. Over 6 years of manufactiring experience
2. Many kinds of stock
3. Competitive price
4. Quality control system
5. Durability testing and critical technical design
6. Customized services
