Abstract
A kit for reworking an improperly installed concrete foundation bolt protruding an insufficient distance above a wood frame structure sill plate includes a combination nut-sleeve having a continuous internal thread, and an elongate cap sized to cover the foundation bolt. The cap is placed over the external threads of the foundation bolt, and a conventional hole saw used to remove material surrounding the foundation bolt. The cap is removed and the nut-sleeve combination installed. The length of engagement of the foundation bolt external thread is effectively increased, solving the problem of the improperly installed bolt in an easy and cost-effective manner.
