Professional Multi-Functional 4-Point Studded Star Knob Set (QNB3011-P2)
Industrial-Grade Torque and Tool-Free Axial Fastening
The POWERTEC QNB3011-P2 is a professional-grade set of ten 4-Point Studded Knobs, specifically precision-engineered to eliminate the tool-dependency and "finger-strain" common in standard jig adjustments. This specialized set is the definitive choice for woodworkers and machinists who need to execute 100% efficient axial securement for T-track assemblies, drill press fences, and custom workshop fixtures. Featuring molded-in zinc-plated steel studs, the QNB3011 series provides the structural leverage and corrosion resistance required to maintain a laminar mechanical bond under heavy vibration.
Constructed with a high-impact thermoplastic architectural logic, these knobs facilitate a Zero-Slip Hand Grip, allowing for maximum torque transfer without the need for wrenches. The 2-inch stud length provides the surgical reach required to navigate thick clamping blocks and multi-layered jigs. Whether you are locking down a table saw fence or securing an automotive rack, these 1/4"-20 knobs deliver the mechanical durability and mathematically uniform tension required for showroom-quality results.
- Elite 4-Arm Logic: Ergonomic star profile maximizes axial leverage, allowing for 100% efficient hand-tightening in high-torque applications.
- Industrial Zinc-Plated Stud: Carbon steel stud build is rust-resistant and survives the high-heat friction of repeat axial adjustments.
- Surgical 2" Reach: Extended stud length ensures a stable mechanical bond through thick components axial to the T-track or fixture.
- Impact-Resistant Polymer: Tough thermoplastic construction resists shop chemicals and survives the abrasive nature of workshop debris.
- Universal 1/4"-20 Fit: Calibrated for a surgical fit axial to standard T-track bolts, threaded inserts, and shop-made jigs.
