Spred-Lok inserts are one-piece, high quality, 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; they are simply pressed in. The mating screw expands the insert locking ft in place and the insert provides a locking action preventing the screw from loosening under vibration. The inserts can be used in through or blind holes and are available with or without a flange.

• Fast & easy press-in installation into any type of plastic
• Screw-expands insert locking it into place
