AUVECO RUBBER WELL NUT 1/4"-20 SCREW 41/64" STEM BLACK 2,000 BULK BOX
- A well nut is a type of fastener used to blindly fasten a piece (much like an molly bolt) and to seal the bolt hole.
- It consists of a flanged neoprene bushing with a nut embedded in the non-flanged end.
- The bolt is passed through one of the pieces to be fastened and threaded on to the nut from the flanged end.
- The non-flanged end is then inserted through the other piece to be fastened.
- As the bolt is tightened, friction from the neoprene flange against the piece being fastened prevents the nut from turning.
- The bushing is compressed by the nut, forming a lip behind the piece being fastened, which compresses the fastened piece and seals the bolt hole.
- Well nuts are not particularly strong, but are useful for sealing holes and/or isolating vibrations.
- 1/4"-20 threads.
