JCBC (Joint Connector Button Cap) screws are high-performance fasteners made from high tensile alloy steel in 12.9 grade. With a black oxide finish for enhanced corrosion resistance, these screws are engineered to deliver exceptional clamping force and fatigue resistance in demanding environments. The low-profile, rounded head allows for a smooth finish and aesthetic appeal while maintaining high load-bearing capability.

JCBC screws are widely used in:

• Furniture & Modular Assemblies: Their aesthetic head and flush-fitting drive make them a preferred choice in knock-down (KD) fittings and wooden panels.

• Automotive & Heavy Machinery: Used where high-strength fasteners are required in compact areas, particularly in transmission systems, engine components, and chassis assemblies.

• Industrial Equipment: Common in robotics, automation systems, and precision assemblies where strength, alignment, and torque control are critical.

• Metal-to-Metal Joints: Their high tensile strength makes them ideal for joining metal components without compromising structural integrity.
