Swivel Bolt Series

Swivel Bolt Series

Chemical bolts fix the screw in a substrate such as concrete through a chemical anchoring agent, and are composed of a screw, a hose, and a washer (standard GB 50367). Common materials are galvanized steel or stainless steel, and the anchoring depth is ≥8d (d is the bolt diameter).

The basket bolt consists of an adjustment rod and a nut with left and right thread, which is used to tighten the wire rope or adjust the tension (standard JB/T 5832). Common materials: Q235 or stainless steel, with galvanized or blackened surface.

Welding studs are cylindrical head welding studs fixed to the parent material by arc stud welding (standard GB/T 10433), made of SWRCH15A or ML15, with tensile strength ≥400MPa and yield strength ≥320MPa.

The head of the flange bolt has a round flange to increase the contact area and disperse the pressure (standard GB/T 5787, GB/T 5789). Common specifications M6-M30, material Q235 or 35CrMo, surface galvanized or blackened.

The head of the butterfly bolt is butterfly-shaped, which is easy to tighten manually without tools (standard GB/T 65). Common materials are plastic (POM, PA66) or stainless steel, with natural or electroplated surface.

The head of the countersunk cross bolt is conical and can be completely embedded in the surface of the connected parts to maintain a smooth appearance (standard GB/T 68). Common materials are carbon steel, stainless steel or engineering plastics (such as nylon 66), with galvanized or natural color treatment on the surface.
