This is an Acorn Nut Fastener & step drill combo kit. It features 10 Acorn Nut Fasteners in the material and size specified below with the corresponding precision step drill for installation.

Acorn Nut Screws are also referred to as "Luke Rivets" for knife handles. Acorn Nut Screws are 3-piece threaded fasteners that work extremely well for knife handle attachment. With this design, you will create a step hole in your handle material that is slightly larger than the shank of the threaded rod. The three-part assembly allows for you to pass the threaded rod precisely through your knife tang hole and handle material, allowing the larger radius of the heads to create a pinch points on both sides of the handle material, where it can then be tightened down to a secure hold. Once the threaded heads have been tightened, they can be sanded to a flush finish with the handle surface. This will result in a smooth, pin-like visual effect on the final knife handle. When used with epoxy and/or thread-locker adhesive, they will create a permanent handle bond.
