3.Product feature and application
In the production of many machinery industries, hexagon allen socket bolts are essential. For example, beverage machinery, plastic machinery, film blowing machinery, etc. all require hexagon allen socket bolts.
4.Production details
Compared with the external hexagonal bolt, the fixing tool of the internal hexagonal bolt has a compact size, which can obtain a larger space during rotation and is more convenient to install.
5.Production qualification
Our factory mainly produces stainless steel fasteners and various non-standard customized stainless steel products. We have more than 10 technical patent certificates, as well as CE certification, SAC / TC 85, ISO90001, CQM quality certification standard certificates and so on.
Our services and advantages
1. We are a factory and we have the right and strength to design and produce.
2. Hex head bolt samples are free.
3. We will answer your inquiry within 24 hours.
4. After sending, we will track the product for you every two days until you get the product.
