Automotive Tool Set Appraisal

Specialized Automotive Puller/Installer Tool with Spline Drive Bolts

This set appears to be a specialized automotive tool designed for a specific task, likely related to engine or chassis components. The main tool consists of a cylindrical body with a T-handle at the top for grip and leverage. Extending from the bottom of this body is a long, threaded rod with a specialized fitting at its end, suggesting it's designed to interface with a specific component. The main body of the tool is made of a light-colored metal, possibly aluminum or a coated steel, showing some minor wear and scuffs consistent with typical workshop use. The T-handle is black, likely made of hardened steel or a similar robust material. There are several additional fasteners or bolts accompanying the main tool. These bolts are made of a yellowish-gold metal, indicative of a zinc or cadmium plating for corrosion resistance. They feature a unique multi-point head, often referred to as a Triple Square (XZN) or similar spline drive, rather than a standard hexagonal head. Many of these bolts show signs of previous use, with slight discoloration and minor marring on their surfaces, indicating they have been tightened and loosened multiple times. One of the longer bolts has noticeable scoring and wear along its shaft, suggesting it may work in conjunction with the main tool's threaded rod or experiences friction during its operation. The overall condition suggests a used but functional set of tools, with typical wear for items found in a professional or enthusiast's garage. No clear manufacturer's marks or model numbers are visible in the provided image; however, the specialized nature of the bolts and the pulling/pushing mechanism of the main tool point towards a dedicated application, possibly for suspension, differential, or steering component removal/installation. The craftsmanship appears to be industrial grade, designed for strength and durability.
