Flat Hex Nut Product Description A flat hex nut is a type of nut with a hexagonal (six-sided) shape and a flat profile. Nuts are fasteners that are used in conjunction with bolts or screws to hold two or more parts together securely. The hexagonal shape of the flat hex nut allows for easy tightening and loosening using a wrench or a socket. Hex nut is an important part of thread bar accessory, it is used in all kinds of highway, railway, municipal construction, large Bridges, soil nailing, foundation pit anchoring, slope anchoring and other engineering construction. Hex Nuts are flat nuts and Spherical nuts, flat nut (upper nut), Spherical nut (lower nut). Commonly used specification is divided into 20 mm, 25 mm and 32 mm, 36 mm, 40 mm, commonly used materials are divided into 45 #, 40 cr material, hardness value is between 28 and 35.

Hot rolled bars are available on the website in all grades and sizes. Select the properties you purchased, such as diameter, hot rolled, cold rolled, corrugated, etc. Hot rolled steel bars are stronger than galvanized steel bars. They prevent cracks in concrete. When used with concrete for construction, thinner concrete is fine. Hot-rolled steel bars are extremely long-lived, cost-effective and responsive. Hot rolled steel bars have proven useful in enhancing the functionality of many commercial enterprises. These include airports, agriculture, fencing, infrastructure and concrete slabs. When you buy hot rolled deformed rebar, you compare various international sellers and narrow down your options based on price, quality and reviews from previous customers. Length: 12m or as per customers' requirements Technology: Hot rolled, right hand Accessories: full hex nut, spherical hex nut, bearing plate, domed nut, anchor bolt, foundation bolt, couplers, spring bar Packing: in bundles Delivery: 15-30 days COMPOSITION: The PSB950 thread bar is made of black steel with a continuous right-handed along the entire length of the thread bar. The continuous threading allows the cut of the bar with different length according to the design requirements and it also improves the adhesion between the bar and grouting.

Anchor plate works closely working with the Nuts. And there are different types like flat,domed,spherical plate etc. Anchor Plates are wooden or metal plates attached to or embedded in brackets and used as anchors (such as for supporting cables). Anchor plates consist of steel plates with welded shear bolts used to connect steel elements to concrete elements. For this purpose, the anchor plates are concreted into the concrete elements. Shear bolts are used as anchors. When installed, the steel plate is flush with the surface, with no concrete on one side. On this side, welding of steel components is possible. Typical Application: Reinforcement of the nut tension and fixation. Different sizes can be processed according to construction requirements. Bearing plates provide a larger bearing surface than standard cut washers, helping to distribute loads more efficiently. The square plate allows it to cover a larger area of surface area than a standard round gasket. This makes them ideal for fasteners required for heavy duty applications.
