These star knobs are seriously handy for all sorts of projects! You get five of them in the pack, each with 1/4-20 threads and 12mm length - perfect for when you need a comfortable grip for tightening and adjusting. The star-shaped design isn't just for looks - it gives you amazing grip and control, making it easy to get the right amount of torque without straining your hands. The combination of galvanized carbon steel (rust-proof and durable) with plastic heads means they're strong but still comfortable to use. The 25mm head diameter gives you plenty of surface area to grip, and the ergonomic shape just feels natural in your hand. They won't slip easily, which is great when you're working on precision stuff. Super versatile too - use them for woodworking clamps, speaker brackets, mechanical equipment, fixtures, or any project where you need reliable clamping action. The quality is noticeable right away - the threading is clean, the finish is smooth, and they just feel well-made. Whether you're replacing old worn-out knobs or adding them to new projects, these little guys will make your life so much easier. No more struggling with hard-to-turn fasteners - these star knobs give you the control and comfort you need for all your workshop adventures!
