FASTENER EXTENSION AND DRIVING TOOL
Abstract A fastener extension 10 comprises a body 12 having a central aperture 14 through which the shank of a normal fastener (e.g., screw, nail or bolt) can extend through, while the head of the fastener is held by the body 12. The body 12 comprises a washer shaped head portion 16 and a tubular shoulder portion 18. The aperture 14 in the head portion 18 comprises a recess 20 which is shaped to receive the head of the fastener extending through the aperture 14. The shoulder portion 18 has an external diameter larger than the shank of the fastener extending through its central aperture 14. The shoulder portion 18 defines a stop surface 21 at a distal end thereof spaced from the head portion 16. The head portion 16 further comprises attachment means 30 formed in the first surface 24, which in one embodiment are three prongs spaced around the aperture 14. The prongs 14 extend in an opposite direction to the shoulder portion 18. 10 1/7 10b 1 (c). 2(c). 24 1()24 14 20 1 (b). 142(b). 30 30 30 30 24 20 & 24 Figure 1 (a). Figure 2(a).
