Abstract

An improved multi-purpose impact hand tool kit for use by electricians, carpenters or similar tradesperson in the building construction industry or other similar industry in applications that require the use of an impact type of hand tool for driving fastening devices such as concrete nails, threaded or unthreaded fastener studs, pins anchor/expansion plugs or similar devices. The improved impact hand tool kit conveniently provides for the tradesperson an elongated shaft provided with a tool end having exterior threads and a threaded bore for attaching male or female threaded attachment ends provided on commercially available fastening devices. The improved hand tool kit can also be used by the tradesperson in general applications that require the use of an impact or non-impact general purpose hand tools such as chisels, punches, and screwdrivers. Such impact or non-impact general purpose hand tools are specially adapted for use with the elongated shaft of the improved impact hand tool kit. The improved impact hand tool kit is also provided with simple reducer adapters which will allow the use of fastening devices or specially adapted general purpose impactor non-impact hand tools having their attachment ends with a reduced thread size. The improved impact hand tool kit is provided with features that add utility, comfort, durability and safety during its use.

Dependent claims

A multi-purpose, impact hand tool kit for driving a plurality of sizes of commercially available fastening devices such as, exterior threaded building fastening devices, interior threaded building fastening devices, and non-threaded impact end building fastening devices, said tool kit comprising:

(a) an elongated shaft, made of hardened material such as steel, provided with a tool end having thereat, exterior threads and a threaded bore, said exterior threads and said threaded bore being provided in a plurality of sizes for threadably attaching to said exterior threaded building fastening devices or to said interior threaded building fastening devices,
said elongated shaft further provided with a hammer impact end at its other end, a wrench head located below said hammer impact end and a shock absorbing handgrip secured to said elongated shaft and located below said wrench head;
(b) a first reducer adapter having one end provided with reduced exterior threads which will threadably attach to said threaded bore of said elongated shaft,
said first reducer adapter provided at its other end with a reduced tool end having thereat a reduced threaded bore, said reduced threaded bore being provided in a plurality of sizes for threadably attaching to said exterior threaded building fastening devices,
said first reducer adapter further being provided with a wrench head at said reduced tool end for torqueing of said first reducer adapter to said elongated shaft whereby continuity of elongated shaft axial strength is maintained;
(c) a second reducer adapter having one end provided with a first set of reduced exterior threads which will threadably attach to said threaded bore of said elongated shaft,
said second reducer adapter provided at its other end with a reduced tool end having thereat a second set of reduced exterior threads, said second set of reduced exterior threads being provided in a plurality of sizes for threadably attaching to said interior threaded building fastening devices,
said second reducer adapter further being provided with a wrench head located between said first and second set of reduced exterior threads for torqueing of said second reducer adapter to said elongated shaft whereby continuity of elongated shaft axial strength is maintained;
and
(d) a third reducer adapter having one end provided with reducer exterior threads which will threadably attach to said threaded bore of said elongated shaft,
said third reducer adapter is provided at its outer end with a tool end comprised of a wrench head with a recessed bore, said recessed bore being provided in a plurality of sizes for holding said non-threaded impact end building fastening devices, said wrench head being provided for torqueing of said third reducer adapter to said elongated shaft whereby continuity of elongated shaft axial strength is maintained.
