BH11 Belt Hooks (also known as treadle belt clips or C-clips) are small metal fasteners used to join the ends of round leather belts on vintage treadle sewing machines. They are essential for maintaining the continuous loop of the belt that transfers power from the foot pedal (rocking pedal) to the machine's handwheel, enabling the treadle mechanism to operate smoothly.

Specifications:

• Part Number: BH11
• Quantity: 10 hooks per pack
• Wire Diameter: 1.7mm
• Hook Length: 16.7mm
