Our white plum/star handle bakelite hand screws (thumb screws) are professionally designed for convenient, tool-free adjustment and fastening, combining practicality, durability, and ergonomic design. Crafted with high-quality bakelite handles and precision-machined metal bolts, these hand-twist screws feature excellent insulation, corrosion resistance, and a comfortable grip, making them ideal for scenarios where frequent adjustment or quick disassembly is required.

 

Available in M4, M5, M6, M8, and M10 sizes, these screws come with two handle styles—plum handle and star handle (six-star knob head)—to meet diverse application needs. The white bakelite handle not only offers a sleek, clean appearance but also provides good electrical insulation, making them suitable for use with electrical equipment, instruments, and machinery where insulation is a priority.

 

The ergonomic knob design allows for easy hand tightening and loosening without the need for additional tools, improving work efficiency in assembly, adjustment, and maintenance. The precision-threaded bolts ensure firm fixation, preventing loosening during use, while the bakelite material is wear-resistant, heat-resistant, and easy to clean, ensuring long-term reliable performance.

 

Widely applicable to industrial machinery, electrical instruments, equipment fixtures, DIY projects, and tool adjustment, these hand screws are perfect for both professional industrial use and daily DIY operations. Each screw undergoes strict quality inspection to ensure consistent dimensions, smooth handle surfaces, and secure thread engagement, delivering convenience and durability for all your adjustment and fastening needs.
