Abstract
A method for installing fastener in a base material. The fastener has a shank having a first end and a second end defining a length, a head provided at the second end, and a thread provided on the shank which includes a leading edge and a trailing edge adapted remove portions of the base material when inserted into the base material. The method includes forming a hole having a diameter which is a nominal shank diameter of the fastener to be installed in the base material. The hole is then filled with an adhesive having a viscosity of 350 cP or less. Finally, the fastener is rotated into the hole such that the adhesive is forced into portions of the base material adjacent to the shank and thread when the thread is fully inserted into the hole.

A method for installing fastener in a base material, the fastener comprising a shank having a first end and a second end defining a length, a head provided at the second end, a thread provided on the shank which includes a leading edge and a trailing edge adapted remove portions of the base material when inserted into the base material, the method comprising:
- forming a hole having a diameter which is a nominal shank diameter of the fastener to be installed in the base material;
- filling the hole with an adhesive having a viscosity of 350 cP or less;
- causing the fastener to be rotated into the hole such that the adhesive is forced into portions of the base material adjacent to the shank and thread when the thread is fully inserted into the hole.
A fastening structure, comprising
- a base material;
- a hole having a diameter which is a nominal shank diameter of the fastener to be installed in the base material;
- a fastener in a bore in the base material, the fastener comprising a shank having a first end and a second end defining a length, a head provided at the second end and adjacent to a top surface of the base material, a thread provided on the shank which includes a leading edge and a trailing edge adapted remove portions of the base material when inserted into the base material, the thread embedded in the base material along a length of the bore;
- and
- an adhesive having an installation viscosity of 350 cP or less embedded into the base material adjacent to the walls of the bore and the embedded threads of the fastener.
