Offering fast and easy press-in installation into any type of plastic, Spred-Lok inserts are high-quality one-piece brass, knurled inserts with a unique, slotted, expandable outside diameter. They can be installed in either thermoset or thermoplastic materials.

No special tooling is required; Spred-Lok inserts are simply pressed in. The mating screw expands the insert, locking it in place, and the insert provides a locking action preventing the screw from loosening under vibration.
