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.

Abstract: A compressed gas gun which includes a bolt assembly which is easily removed without the necessity of disassembling the gun or special tooling. The bolt is located at the back of the gun barrel and operatively connected to the hammer assembly by a retracting pin member positioned within an aperture formed in the hammer assembly. By depressing a spring tensioned component at the rear of the bolt, the restraining pin member is caused to move along a groove, or channel, formed in a channel member, raising the pin member from the aperture in the hammer assembly from the gun and allowing the bolt assembly to be removed from the gun. The bolt assembly is reinstalled by reversing the above process.
