Helicoil Installation Kit Appraisal

NAPA Balkamp Helicoil Thread Repair Kit, Size 5/16-18

The item is a Helicoil Thread Repair Kit, manufactured by Balkamp, a brand associated with NAPA Auto Parts. The kit is packaged in a clear, red-bordered plastic blister pack, designed for retail display, indicated by the metal grommet at the top for hanging. The packaging is somewhat aged, showing some minor dust and surface wear from storage, but appears to be largely intact without tears or significant damage. The kit contains at least three distinct metal tools: a threaded coiled insert (likely a Helicoil insert itself), a thread cutting tap, and a solid bolt with a hexagonal head and threaded end. There's also a black, irregularly shaped plastic or rubber piece, possibly an installation tool or a protector. The tap clearly shows the "NAPA" logo and "BALKAMP" branding on the packaging, along with "Helicoil Thread Repair Kit." The item number "770-3045" is printed on the upper right of the packaging. Visible specifications include "Size: 5/16-18" and "Drill Size: I/64 (.328)," indicating the specific thread and drill dimensions for which the kit is intended. The tools themselves appear to be made of steel, exhibiting a metallic gray finish typical of such hardware. There are no obvious signs of rust or heavy corrosion on the visible metal components, suggesting reasonable storage conditions. The overall appearance indicates a new or unused item, still in its original packaging, likely from the late 20th or early 21st century given the packaging style and branding. The craftsmanship appears to be standard for mass-produced automotive repair tools, functional and utilitarian in design. No unique markings or significant wear are discernible on the tools themselves, as they are sealed within the packaging.
