Premium Black Star Fluted Clamps for Secure Shop Work
✔️ 2 Pack Black 3/8-24UNF Knobs, 40x17mm, Reinforced Metal Core

This set includes two black star clamping knobs built for quick manual tightening on industrial racks and furniture assemblies. You get substantial diagonal grip zones that lock firmly onto 3/8 inch 24 UNF studs without rolling away. Mechanics and DIYers mount these handy handles on drawer panels, lathe controls, and instrument boxes where frequent tuning happens daily.

✅ Standard 3/8 24 UNF thread aligns with most industrial mounting studs
✅ Dense plastic body accepts heavy torque without cracking under shop vibrations
✅ 40mm 1.57 inch wide grip surface multiplies hand leverage during fast turns
✅ 17mm 0.67 inch tall silhouette keeps moving parts clear of rotating machinery

💡 What makes fluted clamping knobs better than smooth round handles for shop equipment?
They channel gripping force through deep ridges that clamp down tight on sweaty palms, taking guesswork out of adjustment runs. The thick internal threading spreads load across the whole knob so fasteners stay straight during rough service.
- Sturdy polymer casings take pounding without cracking when dropping off tool carts
- Corroded bolt shafts slide smoothly past rusted steel cores for easy swap outs
- Broad side profiles multiply hand strength so operators fine tune tension with minimal effort
