It sets itself apart from other adjustable wrenches, however, by having the jaws much more parallel to the handle, unlike other adjustable or monkey wrenches that have the jaws perpendicular. Modern crescent wrenches, however, forego the worm gear and use a slide adjuster instead. Crescent wrenches are used primarily to turn nuts and bolts of various sizes, reducing the number of wrenches you have in your toolbox. Fun fact: the Crescent company actually created a crescent wrench that two sets of jaws, one on each end of the handle.

The Allen wrench is, just like the crescent wrench, actually a brand name for a category of tools called Hex Keys, which in turn were used on another type of tool called recessed hex-driven safety screws. To use, you simply stick the shorter end into the six-sided hole of a screw and use the longer end to turn it. They are uniquely designed to work only for the screws that it comes with. This is due to the fact that the immoveable jaw is propped up by some flat surfaces that are on the left and right sides.

This means that the stress of the bending is less. It is important that anyone using the wrench should not put a lot of pressure on the wrench while using it on a bolt. This is because that would cause the mouth of the wrench to expand. If the mouth of the wrench expands, it can no longer fit the bolt or nut heads. Additionally, the excess pressure can deform the head of the bolt. There is another kind of crescent wrench which has a mouth that takes the shape of four sides of a hexagon.

It is used mainly on hex nuts, hex screw caps and hex bolts. The crescent wrench is specifically used to loosen or tighten hex heads or nuts. The wrench is not usually used in craft shops. Where you can mostly find their application is on vehicles for repairs.

The crescent wrench like the lug wrench could be used on trucks and cars in varying ways. Mechanics advice that even motorcycle riders should have a crescent wrench under their seats as it can come in handy on some days. The wrench has three parts: the moveable jaw, the fixed jaw that is attached to the handle, and the worm screw. It is the worm screw that helps to alter the space in between both jaws. Button's Pattern pliers were a style of wire-cutters first introduced by J.

These pliers were typically produced with two or three wire-cutting slots situated at the sides or between the jaws. The illustrations of these early models show the angled sides of the jaws with a flat planar surface. The next two figures show examples of the Crescent Button's pliers, with minor differences in construction and marking.

The top inset shows a side view of the pliers, illustrating the "Checkerdot" gripping pattern on the handles. Note also that the angled outer face of the jaws has been ground to a curved surface, with an abrupt termination just before the cutting slot.

The middle inset shows a close-up of the jaw construction. Note that the cutting slot between the jaws is at a right angle to the faces. For these pliers the cutting slot between the jaws is slightly offset from a right angle.

In Crescent introduced a line of alloy-steel tools under the "Crestoloy" trademark. The new alloy steel was used not only for adjustable wrenches, but also for certain types of fixed-pivot pliers that could benefit from the stronger steel.

After the introduction of Crestoloy, Crescent continued to offer adjustable wrenches and some pliers models in the older carbon steel. By Crescent was offering more than a dozen models of Crestoloy pliers, and additional models were added in later years. Table 4 below summarizes the available models by catalog year. Readers familiar with Utica pliers may note that some of the model numbers are the same as the corresponding Utica tool.

In Crescent began using "Crestoloy" alloy steel for a new line of adjustable wrenches. The extra strength of the alloy steel allowed the new wrenches to be thinner and lighter than the older models, but still stronger.

The overall length is 4. The finish is chrome plating with polished faces. The maximum head thickness was measured at 0. The top inset illustrates the dimpled gripping pattern on the handles, a pattern seldom seen on Crescent pliers. Crescent generally preferred plain handles, and when it did use a gripping pattern, it was usually the "Checkerdot" pattern. The finish is plain steel with polished faces. The markings are etched rather than stamped and are a bit difficult to read.

In addition to its well known adjustable wrenches and pliers, Crescent also offered a substantial selection of striking tools such as chisels, punches, and star masonry drills. The overall length is 5. In the mid s Crescent decided to become more of a full-service tool company and broadened its product line to include such items as fixed wrenches and socket tools. These changes occurred before the company's reorganization as Crescent Niagara and subsequent tool-company acquisitions.

The pending status refers to patent 2,, , filed by T. Angquist et al in and issued in , with assignment to the Crescent Niagara Corporation. This particular ratchet was acquired as an unused "new old stock" item in its original box. Since the labeling on the box does not mention Crescent Niagara, it's likely that the production occurred before the company's reorganization in The inset shows the box-joint construction of the pliers and the "Checkerdot" gripping pattern on the handles.

This next figure shows a different style of fencing pliers with a prominent "horn" for pulling staples. By the Crescent catalog had been expanded considerably with the addition of tools from these acquired companies. The fractional sizes are forged into depressed panels on the ends. This wrench has an odd combination of design and marking features borrowed from the tool companies acquired by Crescent Niagara. The design includes features found in late Barcalo production, in particular the raised panel on one side and the depressed panel on the reverse, as well as the forged-in sizes in the faces.

The shank aslo has a forged-in number "22" on both sides. This wrench resembles the Barcalo combination wrenches of the early s with its use of the "Taper Design" box end. This ratchet is covered by patent 2,, , issued to T. Angquist et al in with assignment to Crescent.

In later years Crescent redesigned its adjustable wrenches, extending the depressed panel in the handle all the way to the adjusting screw.

At the opposite end, the paneled region was terminated sharply in a line, leaving a squared off area around the hole. Previously the hole had been within the panel, and had not had a ridge around it. Based on a review of catalog illustrations and magazine advertisements, the new handle design went into production sometime between and , and by was being used for Crescent's plain finish non-Crestoloy wrenches. By the new design was being used for all adjustable wrenches except for the double-ended models.

The catalog refers to the "open handle design" as an improvement in the ease of adjustment, and the design gave their wrenches a distinctive appearance as well. From our standpoint, the redesign had an additional advantage, in that it makes it easier to identify Crescent as the contract maker for other brands. However, later wrench production from Diamond Tool used a similar handle design. This next figure shows a later wrench with a plain finish, marked with "Alloy" instead of "Crestoloy".

The shank also has a forged-in code "34" near the hanging hole. In still later production the forged-in markings were replaced by stamped markings, except for some small production codes at the end of the handle.

Introduction The Crescent Tool Company was an early tool maker best known for its eponymous crescent wrench. Danielson Company. The Crescent Wrench Is Born Crescent's pliers were well received, but the company soon became better known as a maker of adjustable wrenches.

The Introduction of Crestoloy In Crescent introduced a line of alloy steel pliers and wrenches under the "Crestoloy" brand.
