Standard fasteners mainly include bolts, studs, screws, set screws, nuts, washers and rivets. There are many structural types of bolts, and most of the heads are hexagonal. For bolts subjected to impact, vibration or variable load, in order to increase flexibility, the polished rod part is made into a thin section or hollow. The seat end of the stud is screwed into the threaded hole of the connected piece, and the nut equipped with the nut end is similar to the bolt nut. The structure of the screw is roughly the same as that of the bolt, but the head shape is diverse to adapt to different assembly space, tightening degree and connection appearance. Set screws have different head and end shapes to accommodate different tightening degrees. There are also many types of nuts, with the hexagonal shape being the most widely used.
Thread-cutting screws feature a cutting or forming tip that creates mating threads in the material during installation. They are used in applications where tapping or pre-drilling is not feasible, such as plastic, metal, or composite materials. Thread-cutting screws may have a pan, flat, or truss head and are available in various thread types and sizes. Sheet metal screws are designed for fastening thin metal sheets, such as roofing, siding, or ductwork. They have sharp threads and a tapered point for easy penetration into sheet metal without the need for pre-drilling. Sheet metal screws may have hex, pan, flat, or truss heads, depending on the application.
Construction: They are used to distribute the load of bolts in structural steel connections and timber framing. Automotive: Washers are crucial for preventing damage to car body panels and ensuring proper tightening of fasteners. Plumbing: They are used with nuts and bolts to create leak-proof connections in pipes and fixtures. Electrical: Washers provide insulation and prevent loosening of screws in electrical components and appliances. Always use washers with nuts and bolts to prevent damage to the underlying material and ensure a secure connection. Choose the appropriate washer type based on the specific application and the type of fastener being used.
Chromate conversion coating is a type of treatment that is often used for screws made of aluminum, zinc, or magnesium alloys. It provides a clear or iridescent finish that improves corrosion resistance and gives the screw a more refined, shiny appearance. This finish is commonly used in the aerospace industry and for electronic components. Recommendation for Clients: If the client requires a high-performance screw with a professional, high-end finish, chromate conversion coating is a great choice. However, this process is typically more expensive than zinc plating, so it should be used for specialized, high-end applications. Read a lot more information on https://www.jm-fastener.com/.
Machinery and Equipment: In machinery and equipment, bolts are used to join large and heavy components that require precise alignment and strong clamping forces. The uniform load distribution provided by bolts prevents damage to the machinery and ensures smooth operation. The ability to disassemble and reassemble bolts without compromising the integrity of the components is crucial for maintenance and repairs. Aerospace Industry: The aerospace industry demands fasteners that can withstand extreme conditions, including high stress, temperature fluctuations, and corrosion. Bolts made from high-strength materials like titanium are used to assemble aircraft structures and components. The reliability and security provided by bolted connections are essential for the safety and performance of aircraft.
Automotive Industry (240–500 Hours): Automotive fasteners used in automobiles, particularly in parts exposed to weather, moisture, and road salt, require 240 to 500-hour salt spray tests. These fasteners are often coated with protective layers, such as zinc plating, to prevent corrosion and maintain their integrity. Corrosion resistance is crucial for automotive safety components, such as suspension bolts, brake systems, and body parts. Aerospace Industry (500–1000 Hours): Aerospace fasteners, which are used in aircraft, helicopters, and spacecraft, are subject to harsh conditions, including high altitudes, humidity, and temperature extremes. As such, these fasteners typically undergo 500 to 1000-hour salt spray tests to ensure their reliability in demanding environments. Aerospace fasteners are often made of high-strength alloys and are coated with special corrosion-resistant materials to ensure their performance over extended periods.
