The Low Profile Knurled Threaded Insert features a knurled body with a smaller diameter, reduced profile head to provide virtually flush installation without special hole preparation. Countersink drilling or dimpling of the parent material can be eliminated. During insertion, the knurled body expands 360° to fill the hole, creating exceptional torque strength and resistance to vibration. A backside flange is also formed, even in multiple thicknesses of materials without any need for adjustments. These inserts are to be used with Grade 5 or Metric 8.8/9.8 mating screws. All sizes available are listed on this page, in a representative sampling of materials, finishes and end options (Open Ends for most versatility, and Closed Ends to eliminate leakage past threads).
