Saltus wrench	scaffolders spanner	Similar in concept to a socket wrench. A Saltus wrench features a socket permanently affixed to a handle. Sockets are not interchangeable as with a socket wrench. The socket often rotates around the handle to allow the user to access a fastener from a variety of angles. Commonly a Saltus wrench is part of a double-ended wrench, with an open-end type head on the opposite side from the socket head.	common

One of the features on the Milwaukee 2767 that stood out is the “Bolt Removal” mode. This was not found on any other impact wrench we tested. On the push-button speed selection at the base of the impact, you can select 1-3. Setting 1 is the slowest and 3, the fastest. The fourth selection is the “Bolt Removal” mode, indicated by a circular arrow designation. When this mode is selected, the user holds their finger on the trigger—once the fastener breaks loose, the Milwaukee senses this and slows the RPM to just 750 to finish removing the nut. This keeps the nut from flying across the shop.

clamp ratchet wrench clamp ratchet spanner An open-ended multi-size ratchet wrench. The ratcheting mechanism allows the nut to be clamped-on or loosened with a reciprocating motion; flip the wrench to change direction of the drive. The wrench takes the advantage of the clamp action to allow multiple sizes in both SAE and metric standards. Each wrench typically will allow up to 3 non-metric sizes and 3 metric sizes. adjustable

Sockets and extensions for impact wrenches are made of high tensile metal, as any spring effect will greatly reduce the torque available at the fastener. Even so, the use of multiple extensions, universal joints, and so forth will weaken the impacts, and the operator needs to minimize their use. Using non-impact sockets or accessories with an impact wrench will often result in bending, fracturing, or otherwise damaging the accessory, as most are not capable of withstanding the sudden high torque of an impact tool, and can result in stripping the head on the fastener. Non-impact sockets and accessories are made of a harder more brittle metal. Safety glasses should always be worn when working with impact tools, as the strong impacts can generate high-speed shrapnel if a socket, accessory, or fastener fails.
Yet another design uses a rocking weight inside the hammer, and a single, long protrusion on the side of the anvil's shaft. When the hammer spins, the rocking weight first contacts the anvil on the opposite side than used to drive the anvil, nudging the weight into position for the impact. As the hammer spins further, the weight hits the side of the anvil, transferring the hammer's and its own energy to the output, then rocks back to the other side. This design also has the advantage of hammering only once per revolution, as well as its simplicity, but has the disadvantage of making the tool vibrate as the rocking weight acts as an eccentric, and can be less tolerant of running the tool with low input power. To help combat the vibration and uneven drive, sometimes two of these hammers are placed in line with each other, at 180° offsets, both striking at the same time.

open-end wrench open-ended spanner A one-piece wrench with a U-shaped opening that grips two opposite faces of the bolt or nut. This wrench is often double-ended, with a different-sized opening at each end. The ends are generally oriented at an angle of around 15 degrees to the longitudinal axis of the handle. This allows a greater range of movement in enclosed spaces by flipping the wrench over. common

flogging spanner This is a specialized thick, short, stocky wrench with a block end to the handle specifically designed for use with a hammer, enabling one to impart great force. Used commonly with large fasteners, especially a nut and stud which both have index marks: the nut is screwed hand-tight, then further tightened with the striking wrench a known number of index marks calculated from the elasticity of the bolt or stud, thus giving precise torque (preload). Striking wrenches also provide shock and high force used to release large and/or stuck nuts and bolts; and when space does not allow room for a large wrench. common

Two wrenches, both nominal size ​5⁄8 in, with a diagram superimposed to show the logic that allows them both to be labeled the same when their actual sizes are clearly different (across-flats distance vs screw diameter). The larger wrench in this photo is from the 1920s or earlier; its face was polished to allow the size stamp to be visible in the photograph.

One issue noticed by a couple of the testers was the placement of the reversing switch. The switch seems to be right in the path of your trigger finger. Sometimes, when trying to go fast, the forefinger would push the switch into the neutral/locked position. This didn’t happen all the time, and it seemed to only be noticeable to those with larger hands.
