Caliber Enterprise is a leading Hex Nuts Manufacturer that offers high quality fastening solutions which are developed to be strong, durable, and stable in performance. Its product Hex Nuts are employed in the construction, machinery, automotive and industrial industry with bolts and screws to fix the joints. These nuts are made of high-grade materials hence have a superior level of corrosion, wear and stress resistance hence can be used in harsh environments. They have accurate threading and uniform sizes which makes them easy to install and fasten in numerous projects.
