Female Threaded Insert

Available in a wide range of sizes and styles, our plastic Wing Knobs offer simple fingertip clamping control and come in both studded and threaded insert versions. The wing design allows for easy torquing operation and is an economical, lighter weight alternative to steel with good chemical resistance.

4-Arm Clamping Knobs provide a secure multilobed grip to position, tighten, and hold fixtures, equipment, and machinery. We offer a large selection of knob sizes, thread configurations and ergonomic grips to meet your design requirements. Our pronged knobs feature a plastic base design that provides excellent chemical resistance and a more economical choice opposed to all-steel versions.
