Hi-Tech Fasteners, Inc. - HSL™ Spring

HSL springs are engineered to provide a reliable and repeatable spring rate when assembled with mating PEM hardware. The spring rate is critical to the successful assembly of your heat sink.

Clamp load will be determined by the spring rate and deflection that is designed into the joint.
