Precision-Engineered Clamping Knob (M8×30mm Thread): This 2-pack set features a hybrid construction with a 3.2cm diameter PP star head and carbon steel threaded shaft, combining lightweight comfort with industrial-strength durability. The precisely machined 8mm threads clamping knob screws ensure smooth engagement while resisting cross-threading during frequent adjustments
Ergonomic Star-Grip Design: The star hand knob tightening screws' 6-point star configuration provides more torque leverage than standard round knobs, with rounded edges that prevent hand fatigue during prolonged use. The knurled perimeter offers slip-resistant control whether wearing work gloves or handling with bare hands in workshop conditions
Multi-Material Corrosion Resistance: The plated carbon steel core resists rust in humid environments, while the UV-stabilized polypropylene head withstands chemicals, oils, and temperature fluctuations, plastic star shaped clamping knob handle is ideal for both indoor cabinetry and outdoor equipment applications
Tool-Free Installation System: Thread replacement star hand knob tightening screws are designed for quick assembly without wrenches, the deep finger grooves allow fully easy manual tightening. The unified black finish maintains a consistent appearance across industrial, automotive, and home DIY applications while hiding grease and dirt buildup
Universal Equipment Compatibility: From speaker stand collars (fits 8mm receiver tubes) to woodworking jigs and machine guards, these hand tightening replacement knobs replace bulky wingnuts and hex bolts. The compact 1.26" profile fits tight spaces where traditional tools can't reach, making adjustments safer around rotating machinery parts
