Conventional screws and nuts have been used for many years majorly in the telecommunication and computer industries. Their usage dates back to around 200 B.C., and their role in attaching components and parts from panels to racks is particularly important. Today, the market is dominated by different types of captive fasteners, suitable for different applications, and have seemed to replace conventional nuts, screws, and bolts.
Captive Screws and Fasteners
Traditional fasteners, screws in particular, were not suitable for attaching moving parts as they often disengage, becoming loose and posing damage risk to sensitive equipment. Captive fasteners, however, are more efficient and offer secure attachment under different conditions.
Fixed and Secured
Unlike traditional fasteners, screw and nuts — that attaches through a clearance hole one side and fastens using a thread mechanism, captive fasteners are melded to the main equipment in a process known as cold forming, creating a firm bond that doesn’t break even when disengaged from the panel. So the screw and bolt cannot separate from the equipment, but it revolves freely in axial motion.
Easy to Assemble and Dissasemble
Custom screws are secure, easy to use, and have low-risk than traditional fasteners. They are designed to withstand wear and tear experienced with traditional nuts, and protect your equipment against stress, vibrations and other mechanical forces such as hydrostatic pressure. Easier to assemble and disassemble as it only involves slight manipulation to detach the bolts. Custom fasteners, especially those that use twist and lock techniques are ideal for assembling furniture. It’s also convenient to remove the nut using a simple screwdriver.
Custom Fastener Options for Your Specific Use
Captive fasteners are available in a range of sizes, configuration and materials such as steel, aluminum, brass, zinc, and nickel. You will find the right custom fasteners for your project but it’s recommended to consult with a reputable manufacturer to help you with the process.
- Captive Nutsor cage nuts are internally threaded fasteners encased in a spring steel cage that easily connects with the studs. Ideal for attaching in hidden locations and can be quickly replaced, if they are loose or over-tightened, without denting the panel finish.
- Weld nuts are fastener options for projects that requires permanent welding. Typically, weld nuts are produced from stainless steel or low carbon steel, and come in a range of types for various use such as twin pilot, slab base, four projection., and single tabs weld nuts.
- Captive Screws are fasteners that feature hexagonal head and designed to lock into pre-drilled holes. Some of the captive screw standard heads are flat, oval, socket, and washer and can be fastened and unfastened using standard screwdrivers. Custom screws can feature unique threading depending on customer’s applications and preferences.
Technology also hasn’t been left out when it comes to the manufacturing of modern fasteners. For example, there is some screw built to attach using thumb pressure and are used to deliver quality melding and excellent fastening under disengaging conditions such as pressure, vibration, shocks, and stresses.
In conclusion, captive screws are more effective and reliable than traditional ones because of various reasons including safety and firm fastening solution. In addition, captive screws are innovative hence can cope with the developments and demands across various sectors.
