Professional 4-Point Threaded Stud Knob Set (QNB3008)
High-Torque Securement for Shop-Built Jigs and T-Track Assemblies
The POWERTEC QNB3008 is a professional-grade set of five 4-Point Threaded Stud Knobs, specifically precision-engineered to provide a reliable and ergonomic tightening solution for your most complex shop fixtures. These male-threaded knobs are the definitive choice for woodworkers who need to secure featherboards, stops, and fences to standard 1/4"-20 internal thread openings or T-track components. Featuring precision-machined steel studs with a zinc plating, the QNB3008 series provides the anti-stripping mechanical bond and elite corrosion resistance required for high-cycle industrial environments.
Constructed from heavy-duty high-impact plastic, these knobs feature an oversized 4-point geometric profile that allows for maximum axial leverage with minimal hand fatigue. The 1-inch long stud provides ample reach for thick jig bases and dual-layer fixtures, ensuring a rock-solid lock every time. Whether you are calibrating a drill press fence or building a custom crosscut sled for your table saw, these industrial-grade knobs deliver the mechanical stability and tool-free convenience required for showroom-quality results.
- High-Leverage 4-Point Design: Ergonomic profile provides superior finger grip and rotational torque for industrial securement.
- Zinc-Plated Steel Studs: Precision threads are hardened to resist wear and are 100% efficient in corrosive shop environments.
- Impact-Resistant Body: Tough black plastic construction resists accidental shop impacts and high-vibration exposure.
- Rapid Tool-Free Adjustment: Eliminates the need for wrenches, facilitating micro-calibrations on fences and jigs.
- Matched Hardware Value: 5-pack ensures you have consistent, high-quality replacements for multiple shop stations.
