6pcs Spring Hinge Inserts Material: Stainless Steel Mounting Style: Pin Length: 18.7mm Hinge/Loop Width: 1.3mm

A set of replacement eyeglass stainless steel spring hinge inserts, to replace broken spring inserts in reading glasses, sunglasses, computer glasses, or plain spectacles temples.

A spring hinge insert is a vital component of flexible eyeglass temples. The insert typically consists of a mechanism head and springs behind and is held on by spring fork or a pin. These spring hinges allow the arms of your glasses to bend and flex, providing a comfortable fit while maintaining stability. When you extend the temple (arm) of the glasses further outwards than its resting position, the tension on this mechanism pulls the arm back inwards, creating a snug fit that lets you know your glasses are always there.
