Combination screws are integrated fasteners consisting of a screw, a washer (usually flat washer and/or spring washer) pre-assembled together. This one-piece design eliminates the need for separate assembly of components, greatly improving installation efficiency and reducing labor costs. They feature reliable clamping force and excellent anti-loosening performance, ensuring stable connections in various application scenarios.Gate valves are essential linear motion valves designed for on-off flow control of fluids. Featuring a gate-like disc that moves perpendicular to the flow path, they offer minimal flow resistance when fully open and reliable sealing when closed. Constructed with robust materials and precision machining, our gate valves ensure long service life, excellent corrosion resistance, and easy operation, suitable for various industrial and commercial fluid handling systems.
