Bolt Hex HD M16

A: Bolt Hex HD M16 are widely used fasteners for attaching construction materials, manufacturing parts, and maintenance parts. These are tempered, quenched, and high tensile screws. They can endure extreme stress since they are both flexible and rigid. These screws can be hot-dipped galvanized for increased corrosion protection, or they can be finished in black oxide, zinc plating, or zinc yellow. In dry conditions, black oxide screws are resistant to corrosion. In moist settings, zinc plating and zinc yellow coatings contribute to durability. Compared to zinc-plated screws, hot-dipped galvanized steel screws have a thicker coating and are more resistant to corrosion.

A: A machine screw is also called a machine screw or a mechanical screw. It is a screw that is assembled in a threaded hole. Generally, a machine screw has a nut. There are many types of screw heads, such as hexagon socket head, hexagon socket head, hexagon socket round head, cross recessed countersunk head, cross recessed pan head, flat head and semi-cylinder head.

A: 1. Bright and burr-free 2. Long life and no aging 3. Strong zinc layer and no rust 4. Grade meets the requirements and is not easy to break (not the higher the grade of the screw, the better the quality. Choose the appropriate grade according to the customer's actual use occasion)
