  • 【Complete Set & Precise Specs】You get 30 pieces of 1/4"-20 star knobs. Each features a 32mm (1.26") head diameter and 12mm (0.47") total height, with standard 1/4"-20 internal threads. This bulk pack saves you multiple trips to the hardware store—always have a spare on hand when you need it most.
  • 【Durable Material & Long-Lasting Performance】Crafted from high-quality engineering plastic with brass threaded inserts, these knobs offer a smooth, corrosion-resistant surface with excellent strength and toughness. The brass-to-steel thread engagement ensures a secure grip that won't strip or cross-thread, even after repeated tightening and loosening—built to last through years of shop use.
  • 【Ergonomic 6-Pointed Star Grip】The 6-point star design fits your natural hand contour perfectly, providing a comfortable, non-slip grip that requires less force to tighten. No more struggling with wing nuts or using pliers—you can hand-tighten these knobs firmly without hurting your palms, even when wearing work gloves.
  • 【Tool-Free Installation in Seconds】Simply align the threaded hole with your bolt or screw and twist—no wrenches or extra tools needed. The screw-in design makes installation, on-the-fly adjustments, and quick disassembly effortless. Swap out fixtures or reposition your setup in seconds, keeping your workflow smooth and interruption-free.
  • 【Versatile Shop Companion】Ideal for a wide range of applications: drill press tables, featherboards, fence clamps, jigs, camera rigs, 3D printer frames, and any equipment that uses 1/4"-20 threads. Whether you're a woodworker, metalworker, photographer, or DIY enthusiast, these star knobs give you reliable, repeatable clamping power wherever you need it.
