Inventors:

Dennis Greco - Glenview IL, US

International Classification:

B25B 13/50
B25B 27/00

Abstract:

A special tool that can engage and manipulate a Jeep mounting screw commonly known as “Jeep Wrangler Hardtop Freedom Top Targa Mounting Knob Screw” Embodiments may include a handle that can contain indentations or ribs totally or partially extending its length for better grip. The handle abuts a flat head. A pair of screw engagement members are mounted on the flat head, separated, and spaced apart a pre-determined distance. The center region between the engagement members can be part of the flat head. Each engagement member is arc-shaped, or semi-circular in cross-section to fit into the knob screw head. The two engagement members are typically mounted in opposition and each extends approximately ⅓ the circumference of the head. This arrangement allows perfect engagement with the Jeep mount screw.
