If you look around you will see that Building Fasteners, Line Fasteners, Marine Fasteners and other types of fasteners are used in many things that are used in our daily life. Although these components are small, they are necessary for many types of equipment. There are different classifications and specification to sort them out and each has its own purpose.
One type of fastener that you are likely to come across often is threaded fasteners. They can have a non-tapered shank or a tapered shank. You can use them to drive into a pilot hole within a substrate or directly into a substrate. Non-tapered shanks are usually paired up with a nut or other mate and then driven into the tapered hole.
There are different types of tapered shanks as well. Coach/lag screws, wood screws, concrete screws – these are just a few of the types. A coach screw is designed to securely fasten wood to concrete or masonry or to fasten heavy timbers to one another. They have an unthreaded shank and a hexagonal drive head. Concrete screws can also be used for fastening metal, wood, or other materials to masonry or concrete. Self-drilling screws are often used with soft steel or other metals and have drill shaped points that cut through the material so that there is no need for a pilot hole.
Non-threaded fasteners come in many different varieties as well. You will find socket cap screws, elevator bolts, hex bolts, carriage bolts, and many others. Carriage bolts (also called coach bolts) have a countersunk head and a square section that is typically made of wood. It grips into the part that is being fixed and prevents the bold from turning further. Each type of non-tapered fasteners has its own characteristics that are designed for different purposes.
These small materials are very important as fasteners. They contribute to the security and stability of the final product. Learning about the types of fasteners helps you to be more efficient at building quality products. Each fastener has a purpose and a use that is utilized to its full capacity to ensure that products are able to do what they are intended to do.
Started my career in the fastener world in 1969 at, Parker Kalon Corp. a NJ based screw manufacturer located in Clifton, NJ working in inventory control, scheduling secondary production and concluding there in purchasing. In 1971 I accepted a sales position at Star Stainless Screw Co., Totowa, NJ working in inside sales and later as an outside salesman, having a successful career at Star I had the desire with a friend to start our own fastener distribution company in 1980 named: Divspec, Kenilworth, NJ. This was a successful adventure but ended in 1985 with me starting Melfast in August 1985 and have stayed competitive and successful to date. Melfast serves the OEM market with approximately 400 accounts nationally.
