Промышленный крепёж — болты, винты, гайки, шайбы, шпильки, анкеры и заклёпки — это несущие компоненты, которые удерживают вместе машины, конструкции и транспортные средства. Его часто называют «рисом промышленности», он определяет безопасность, срок службы и надёжность любого узла. В этом руководстве рассмотрены типы крепежа, классы прочности ISO/SAE/ASTM, материалы, покрытия и выбор применения, чтобы помочь вам подобрать правильный крепёж для любой высоконагруженной программы.
Промышленный крепёж — это стандартизированный механический компонент, используемый для соединения двух или более деталей посредством разъёмного резьбового или неразъёмного безрезьбового соединения. В отличие от сварки или клеев, крепёж позволяет разбирать узел для обслуживания, ремонта или замены — что критично для тяжёлой техники, автомобилей и несущих конструкций. Четыре ключевых инженерных свойства любого крепежа — предел прочности, предел текучести, коррозионная стойкость и усталостная долговечность, — определяются материалом, термообработкой и процессом накатки резьбы.

WashersConcave hole square washers are a type of hardware component that is used in various industries for fastening applications. These washers have a unique design, with a concave hole in the center and square shape around the edges. This design allows for a more secure and stable fastening of bolts and screws.
WashersSteel square gasket washers are a type of washer that is commonly used in various industries for sealing applications. These washers are made of steel and have a square shape, which allows them to provide a secure and tight seal when used with bolts or screws.
WashersSquare washers have a larger surface area than round washers with the same outside diameter. When applied to wood, square washers provide a great deal of friction. This type of gasket is wider and thicker than most round gaskets. The square outside diameter washers is suitable for wood construction, automotive engineering and machinery. Square washers are designed to eliminate rotation problems and are suitable for small Spaces that are incompatible with round washers.
WashersThe serrated lock washer is fitted on the bolt with the nut, which can play the role of locking and preventing loosening.
WashersGasket spring lock washers are essential in many mechanical and industrial applications. These specialized washers are designed to provide a secure and reliable connection between two surfaces while also preventing leaks and maintaining proper pressure.
WashersDIN126 Flat gasket round washers are a type of sealing washer that is commonly used in various industries. These washers are designed to provide a flat, smooth surface for distributing the load of a fastener, such as a bolt or screw, and to create a tight seal between the fastener and the surface it is being tightened against.
WashersDIN6916 Round Washers are a type of washer that conforms to the DIN6916 standard set by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. These washers are specifically designed to be used with high-strength structural bolts to provide a larger bearing surface and prevent the bolt from pulling through the material.
ScrewsThreaded Nail Welded Eye Screws are specialized fasteners that combine the functions of a traditional screw with the added benefits of an eyelet for easy attachment. They are commonly used in construction, woodworking, and various industrial applications due to their strength and versatility.
ScrewsSelf-drilling screws are fasteners designed for a variety of construction and industrial applications. As the name suggests, these screws have a unique eye-shaped ring at one end that makes it easy to attach ropes, cables, or other fastening devices. The self-drilling ability of these screws means they can create their own pilot holes, making them very convenient to install on a variety of materials, including wood, metal, and concrete.
ScrewsEye Hook Screws, also known as eye bolts or screw eyes, are versatile fasteners designed with a circular eye at one end and a threaded screw at the other. They are commonly used to hang lightweight items like picture frames, plants, and decorations, offering a secure and easy way to attach objects to various surfaces. Whether for home or industrial use, Eye Hook Screws provide a reliable solution for a wide range of hanging tasks.

ScrewsFlat round inverted screws, also known as countersunk screws, are a type of fastener commonly used in woodworking, metalworking, and other industries. These screws have a flat head with a conical underside that is designed to sit flush with the surface it is screwed into.
ScrewsSquare neck screws, also known as carriage bolts or coach bolts, are a type of fastener commonly used in woodworking and construction. These screws have a square neck just below the head, which prevents them from turning when the nut is tightened. This design makes them ideal for applications where the bolt must remain stationary while the nut is tightened, such as attaching a hinge to a door or a latch to a gate.
ScrewsInternal Hex Head Galvanized Screws are a type of fastener that feature a hexagonal head with a recessed internal hex drive. These screws are commonly used in construction and woodworking projects due to their strong grip and resistance to corrosion.
ScrewsCSK Head Self Drilling Screws are a type of screws that are commonly used in construction and manufacturing industries. These screws have a flat head with a countersunk shape, which allows them to sit flush with the surface they are screwed into. The self-drilling feature of these screws means that they have a drill bit at the tip, allowing them to create their own pilot hole as they are screwed in.
