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

Corby Bolts are used for knife handle fasteners. With this design, you will create a step hole in your handle material that is slightly larger than the shank of the fastener. The two-part assembly allows for you to pass the shank precisely through your knife tang hole and handle material, allowing the larger radius of the Corby Bolt heads to create a pinch point on both sides of the handle material where it can then be tightened down to a secure hold. Once the bolt has been tightened, it 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.
