Based on the earlier Kelly tool, the Halligan is a multipurpose tool for prying, twisting, punching, or striking. [8] It consists of a claw (or fork), a blade (wedge or adze), and a tapered pick, which is especially useful in quickly breaching many types of locked doors. One variant of the Halligan has a heavy sliding collar on the shaft.
A Kelly Tool in the NYC Fire Museum (2nd from left) The Kelly tool is a tool used in fire and rescue service for forcible entry and other prying and striking tasks. The predecessor of the Halligan bar , it has largely been superseded by the latter, but still sees some use.
A screw extractor held in a tap wrench. A screw extractor is a tool for removing broken or seized screws.There are two types: one has a spiral flute structure, commonly called an easy out after the trademarked name EZ-Out; [clarification needed] the other has a straight flute structure.
A set of metric spanners or wrenches, open at one end and box/ring at the other. These are commonly known as “combination” spanners. A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning.
A bolt cutter, sometimes called bolt cropper, is a tool used for cutting bolts, chains, padlocks, rebar and wire mesh. It typically has long handles and short blades, with compound hinges to maximize leverage and cutting force. A typical bolt cutter yields 20 kilonewtons (4,500 lb f) of cutting force for a 250 newtons (56 lb f) force on the ...
The claw tool (also known as the Hayward Claw Tool) is a forcible entry tool used by firefighters, made of steel, that has a hook on one end and a forked end on the other. The tool was a major component in the Fire Department of New York during the early 20th century.
The tool is simple, small and light. The contact surfaces of the screw or bolt are protected from external damage. There are six contact surfaces between bolt and driver. Very small bolt heads can be accommodated. The tool allows the use of headless and recessed-head screws. The screw can be held by the key while it is inserted into its hole.
Multi-jackbolt tensioners (MJTs), registered under the trademark Superbolt or Supernut, are designed to decrease the torque required to tighten large bolted joints. One of the major problems associated with traditional bolt tightening methods is as the diameter of the bolt increases, the amount of torque required to tighten it increases in the third power of the diameter.
