Manufacturers sometimes affix objects together with the assistance of mechanical devices called “fasteners.” Popular fasteners include bolts, buttons, clips, rivets, and screws. In some cases, fasteners require two coupled components working together in unison. Other fasteners function as standalone units.
Manufacturers sometimes purchase fasteners providing dimensions suitable for product specifications. However, today companies frequently commission the design and manufacture of bespoke or custom fasteners specifically designed to fit the parameters required by their goods. By obtaining customized fasteners, they seek to enhance product quality.
Screws have become very popular fastening devices. Today manufacturers create these fasteners in a myriad of designs and sizes. They use screws to affix or secure a variety of constituent parts, including items made from metals, woods, plastics, composites, and other materials.
Many modern screws include both a head and an adjoining pointed, helically-threaded shaft. The dimensions and conformations of a screw’s head, shaft and threads vary widely between different types of screws. Screws occur as either individual fasteners or as coupled fasteners with both male and female threaded components.
Some contemporary manufacturers produce screws and bolts which strongly resemble one another. Bolts generally require the use of nuts, and may utilize ribbed shafts inserted through pre-drilled holes. By contrast, screws usually embed directly within a component with the assistance of a threaded pointed shaft and twisting or driving. Some designs require the use of male and female helically threaded screws, but others do not.
Engineers have developed a wide variety of different types of screws. These products occur in variable sizes and dimensions, and some bear strong similarities to bolts. Some of the most popular include these categories:
Sheet Metal Screw (also called a “Drive Screw”): Intended for insertion into metal, this screw displays a broad head and a shaft with prominent male helical threads and a distal conical point on the end to facilitate piercing metal surfaces. Manufacturers create depressions in the head to fit the shape of specific drivers.
Machine Screws (also called a “Cap Screw”): A screw which resembles a bolt, it will fit within mechanical assemblies. It displays extensive helical threads or ribbing on a blunted shaft. Some machine screws fasten items using coupled male and female threads.
A Dowel: A screw without a cap containing two male helical threads on opposite end of the pointed shaft. The shaft embeds into materials on both ends to hold them together.
As widely used fastening devices, screws have received extensive attention from inventors and engineers. Both the raw materials utilized during screw fabrication and the numerous applications for screws demonstrate the importance of screw fasteners from a commercial standpoint. Like bolts and rivets, screws perform vital fastening roles.
A variety of raw materials enable manufacturers to create screws. However, since these fasteners require strength and durability, by far the largest percentage of screws consist of steel or stainless steel. Manufacturers do sometimes produce screws from brass, aluminum, titanium, plastic, wood, and other materials. In some cases, screw manufacturers apply finishes to screws. For example, an automaker may powder coat or electroplate the head of a screw within an automotive assembly for aesthetic reasons. Manufacturers performing assembly processes sometimes insert screws using automated machinery. Some small production facilities use manual screw drivers or electric power drills to affix screws into place during assembly.
Today screws enjoy wide utility in virtually every economic sector. Screws figure prominently in the production of many consumer items, such as furniture. However, they also perform important roles in construction, industrial manufacturing, transportation, energy production, biomedicine, and many other fields.
Developing a custom screw gives a manufacturer better assurance the screws used during an assembly process will meet required specifications with precision. Fewer product rejections may occur during quality assurance testing, for example. Three varieties of screws demonstrate the diversity of this fastening system today:
Custom Screw: Manufacturing companies may request assistance designing and making custom screws meeting specified parameters. Today the benefits of using a custom screw during a large production run sometimes more than offsets the costs involved in taking this step. Custom products designed to meet the dimensional requirements of particular products may result in fewer rejected parts. As with many other customized metal parts, screw manufacturers can automate their production facilities to generate large quantities of custom screws. Computerization and automation have significantly increased manufacturing capabilities in many industries.
Custom OEM Screw: In some situations, companies invest in the development of proprietary custom original equipment manufacturing screws. Designers may seek to ensure an OEM screw functions seamlessly as a component of a specific brand or brand model. This decision frequently offers advantages within a mass production setting. For example, a custom OEM screw may function compatibly with custom tools utilized by the manufacturer to promote more rapid assembly. If your enterprise decides to create custom OEM parts (including custom OEM screws), Bunty LLC offers valuable resources to assist you with this project!
Machined Screw: In some situations, a manufacturer may machine a work piece to create a machined screw for a desired purposes. If the screws purchased in bulk by a manufacturer don’t fit an assembly for instance, in certain cases the enterprise may opt to use machining to modify these fasteners, e.g. by applying threading in desired locations or by changing the head of the screw to fit drivers used by the manufacturer.
