TwisFit® lock rings are designed for use with our TwisFit® template bushings to secure the bushing to the fixture plate during installation. The left-hand thread design tightens under load, helping prevent loosening or rotation during drilling operations. Made from aluminum, the lock ring provides positive locking force between the bushing and plate, helping resist pull-out and maintain alignment. Lock rings are reusable and interchangeable within the TwisFit® system.
