Tension springs are designed to give a specific pull force when extended to a a specific length. Our tension springs have a material dimensional range from 0.15mm - 5.0mm.
Most common ends are different types of end loops and hooks, there are also a wide range of other mechanical attachment possibilities such as coiled in and screwed in attachments. Examples are, half hooks, German loops, English loops, extended hooks, side hooks, side loops, screw plugs and screw shackles.
