Making the right tool selection for the job can make a big difference in productivity and work quality. Certain tools can be utilized to increase speed and efficiency, but they can also impact workplace safety.
Eye screwbolts are one such tool. Thus, the way eye bolts are chosen and used can make a significant difference between a safe workplace and one that poses a danger. Eye bolts are one of the most popular pieces of hardware in material handling, composed of a threaded shank with a ring or eye at one end. Often, eye bolts are threaded into wood or steel posts and are supported by a nut. For lifting objects, a rope or cable is fed through the ring.
An eye can be completely closed or bent to form a loop. Angle lifts should only be performed with bent eye bolts in light duty applications. You can choose between rated and unrated eye bolts. With rated eye bolts, users are assured of quality and stated lifting capacities.
Kinds of eye screwbolt
Eyebolts are most commonly used in industrial applications as nut eye bolts, machinery eye bolts and screw eye bolts. Each type is available in two styles: plain and shoulder. Both styles are available in a variety of sizes and finishes.
- Angular loads should not be applied with regular nut eye bolts, also called plain pattern eye bolts, as they can bend or break when applied.
- With shoulder nut eye bolts, you can apply loads at any angle you like, but keep in mind that the rated capacity will be drastically reduced. In an eye pattern lifting system, the shoulder bears against the seat and reduces the bending stress on the shank.
- The lifting eye of an angled lift is subjected to additional stress beyond that of the load being hoisted. Because of this, it is recommended to avoid angled lifts whenever possible.
- Lag eye bolts are used to thread into wood or lag anchors using a screw thread.
The rated capacity must be reduced if, however, an angular lift is needed with a properly selected and inserted lifting eye. Both plain pattern and shoulder pattern-lifting eyes can be used for vertical lifts, in theory.
However, angular lifts do not guarantee to never occur, so shoulder pattern lifting eyes should be used whenever possible. Eyebolts that are designed for machinery are bolted into tapped holes rather than being secured with nuts.
Material of eye screwbolt
Various materials are used in eye bolts, but carbon, stainless and alloy steel are the most common. Iron, chromium, manganese, silicon, nickel, molybdenum, and very little carbon, are rust-proof.
The corrosion resistance of stainless steel eye bolts makes them ideal for marine applications. The smooth appearance makes this type of eye bolt ideal for architectural applications. Makes it a popular choice for pharmaceuticals and food processing industries.
Eye screwbolts made of alloy steel are ideal for cold weather applications. In temperatures below -1°C (30.2° F), alloy steel eye bolts should be used for lifting projects.
By dipping standard carbon steel into molten zinc, galvanized steel eye bolts get a more layer of corrosion resistance. Thus, galvanized eye bolts are ideal for outdoor applications due to their resistance to the elements. Galvanized eye bolts, but, have a rough finish that can flake or peel; stainless steel eye bolts provide a superior finish.
Eye screwbolts are available in various sizes, as mentioned before. Various loads/weights need to be lifted, hence the reason for this.Rated Capacity or Rated Working Load refers to the safe load an eye bolt can lift. According to its rating, an eye bolt can lift a given load when it is loaded through its shank.
Conclusion
Bolts are more durable than screws and other fasteners. A variety of bolt types and sizes are available. Furthermore, they can be used with various materials, including metal, wood, and concrete. In addition, bolts are available in a variety of materials, such as steel, stainless steel, bronze, brass, and nylon. Up to 90% of all bolts are made of steel, making it the preferred material among manufacturers.
Additionally, there are twin fast screws, security head screws, and sheet metal screws. And like their bolt counterparts, screws are available in a range of materials.
