    DIN1480 metal rigging hot-dip galvanizing/electro-galvanizing

    $12.00

    DIN1480 is a German industrial standard that specifies the requirements for metal rigging hardware, such as turnbuckles, eye bolts, and shackles. Here are some key details about the galvanizing options for DIN1480 metal rigging:

    Hot-Dip Galvanizing:

    • The metal components undergo a hot-dip galvanizing process where they are immersed in a bath of molten zinc.
    • This results in a thick, durable zinc coating that provides excellent corrosion protection, especially for outdoor and marine applications.
    • The hot-dip galvanized coating is metallurgically bonded to the underlying steel, providing long-lasting protection.
    • Hot-dip galvanizing is typically specified for high-strength, load-bearing rigging hardware that requires maximum corrosion resistance.

    Electro-Galvanizing:

    • Electro-galvanizing is an electroplating process that deposits a thin layer of zinc onto the metal surface.
    • The electro-galvanized coating is thinner than hot-dip galvanizing and provides moderate corrosion protection.
    • Electro-galvanizing is a more economical option compared to hot-dip galvanizing.
    • Electro-galvanized rigging may be suitable for indoor or moderately corrosive environments where the reduced corrosion protection is acceptable.

    The choice between hot-dip galvanizing and electro-galvanizing for DIN1480 rigging hardware depends on the specific application, environmental conditions, and budget considerations. Hot-dip galvanizing is generally preferred for critical, high-strength rigging used in outdoor or marine settings.

  • DIN6334 long hexagonal nut galvanized hexagonal nut connector hexagonal nut

    $1.20
    1. DIN6334 – This refers to the German industrial standard (DIN) for a specific type of long hexagonal nut, in this case, DIN6334.
    2. Long hexagonal nut – This is a type of nut that has a longer than standard hexagonal shape, which provides more surface area for tightening and distributing the load.
    3. Galvanized – This means the nut has been coated with a layer of zinc to provide corrosion resistance, making it suitable for outdoor or humid environments.
    4. Hexagonal nut – A nut with a hexagonal shape, which is a common design that allows for easy tightening and removal using a wrench or socket.
    5. Connector – In this context, the hexagonal nut is likely being used as a connector, meaning it is used to join or attach two components together, such as a threaded rod and another structural element.

    So, in summary, a DIN6334 long hexagonal nut is a specific type of galvanized, hexagonal-shaped nut that is designed to be used as a connector or fastener in construction, engineering, or industrial applications where a longer than standard nut is required for increased strength and load distribution.

    These types of nuts are often used in conjunction with threaded rods, bolts, or other threaded fasteners to create secure, adjustable connections between different components or structures.

  • DIN933 hot-dip galvanized external hexagonal bolts

    $5.00

    DIN933 is a standard for hexagonal head bolts in Germany. Here are some key details about DIN933 hot zinc layer outer hexagonal bolts:

    • Material: The bolts are made of steel and have a hot-dip galvanized (zinc-coated) finish on the outer surface.
    • Head Shape: The head has a regular hexagonal shape.
    • Thread: The bolts have a metric ISO thread.
    • Strength Class: Typical strength classes for DIN933 bolts are 4.6, 5.8, 8.8, and 10.9, indicating the minimum tensile strength of the bolt material.
    • Dimensions: The bolt diameter, length, and other dimensions follow the specifications outlined in the DIN933 standard.
    • Applications: These hot-dip galvanized hexagonal head bolts are commonly used in outdoor and corrosive environments where resistance to rust and weathering is important, such as in construction, machinery, and automotive industries.

    The hot-dip galvanized coating provides enhanced corrosion protection compared to uncoated steel bolts. The hexagonal head shape allows for easy tightening and loosening using a wrench or socket.

  • Embedded bolts high quality carbon steel L-shaped/9-shaped/U-shaped

    $5.00
    1. L-shaped embedded bolts:
    • These are bolts that have an “L-shaped” bend or hook at one end.
    • The L-shaped end is embedded into concrete or masonry during construction, providing a secure anchor point.
    • The straight end of the bolt protrudes out of the concrete, allowing it to be connected to other structures or components.
    1. 9-shaped embedded bolts:
    • These have a “9-shaped” or J-shaped bend at one end, similar to the L-shaped design.
    • The curved end gets embedded into the concrete, while the straight end sticks out for connecting other parts.
    • The 9-shape provides additional surface area and grip within the concrete.
    1. U-shaped embedded bolts:
    • These have a U-shaped bend at one end, rather than an L or 9 shape.
    • The U-shape creates a more secure anchor within the concrete.
    • Like the other designs, the straight end protrudes for connecting other components.

    In all cases, these embedded bolts are typically made from high-quality carbon steel for strength and durability. The carbon steel provides excellent load-bearing capacity and resistance to corrosion and wear.

    These types of embedded bolts are commonly used in concrete foundations, walls, floors, and other masonry structures to provide secure attachment points for things like machinery, equipment, railings, or other building components that need to be firmly anchored in place.

    Railway track fasteners/connectors

    $12.00

    let’s discuss the various types of railway track fasteners and connectors:

    Rail Fasteners:

    • These are the devices used to secure the steel rails to the sleepers (ties) or concrete trackbed.
    • Common rail fasteners include:
      • Spikes – Large, heavy-duty nails driven through the rail base into the sleeper.
      • Clip fasteners – Spring-loaded clips that grip the rail base and are secured to the sleeper.
      • Elastic fasteners – Resilient clips or plates that allow some movement while holding the rail in place.
      • Bolted fasteners – Bolts that pass through holes in the rail base and into the sleeper.

    Rail Connectors:

    • These are the devices used to join consecutive lengths of rail together.
    • The main types of rail connectors include:
      • Fishplates (joint bars) – Steel plates bolted to the ends of adjoining rail sections.
      • Compromise joints – Used to connect rails of different sizes or profiles.
      • Insulated joints – Provide electrical isolation between rail sections.
      • Welded joints – Rails are fused together, creating a continuous, seamless connection.

    Other Track Hardware:

    • In addition to fasteners and connectors, other key track components include:
      • Tie plates – Steel plates that distribute the load from the rail to the sleeper.
      • Rail pads – Rubber or plastic pads placed between the rail and sleeper to dampen vibrations.
      • Anchors – Devices that resist longitudinal rail movement and prevent track buckling.
      • Insulators – Used to electrically isolate the rails from the ground.

    The specific choice of fasteners, connectors, and other hardware depends on factors like:

    • Track type (e.g. ballasted, slab, or heavy-haul)
    • Train speeds and axle loads
    • Environmental conditions (e.g. temperature extremes, corrosion)
    • Maintenance requirements and ease of installation

    Proper selection and installation of these railway track components is critical for ensuring safe, efficient, and long-lasting track infrastructure.

  • Shear nails/bolts/welding nails

    $0.50

    let’s take a closer look at the different types of fasteners used for securing solar/photovoltaic brackets:

    Shear Nails:

    • Shear nails are designed to resist lateral or shear forces, which is important for securing solar brackets.
    • They have a thicker shank and sometimes a larger head compared to standard nails.
    • Common examples include ring shank nails and screw shank nails.
    • Shear nails need to penetrate deeply into the wood framing, typically at least 1.5-2 inches, to provide a strong connection.
    • They are commonly used for attaching solar brackets to wooden roof structures.

    Bolts:

    • Bolts, along with nuts and washers, offer a more secure connection than nails, especially for attaching to metal or concrete surfaces.
    • Common bolt types used for solar installations include lag bolts, hex bolts, and carriage bolts.
    • Bolt size, length, and material (e.g. stainless steel) need to be carefully selected based on the application.
    • Bolts can provide higher pullout resistance compared to nails.

    Welding:

    • For metal-framed structures, the solar brackets may be welded directly to the frame.
    • This creates an extremely strong and permanent connection.
    • Welding is often used for ground-mounted or pole-mounted solar installations where the frame is made of steel.
    • The welding process needs to be performed by a qualified professional to ensure proper technique and structural integrity.

    In addition to the fastener type, other important considerations include:

    • Corrosion resistance – Fasteners must be able to withstand outdoor weathering.
    • Pullout resistance – The fasteners need sufficient grip strength to prevent the brackets from pulling out.
    • Ease of installation – Quick-install features can simplify the mounting process.

    The specific fastener requirements will depend on the solar racking system, installation site conditions, and local building codes. Consulting with the solar equipment manufacturer or a structural engineer can help determine the optimal fastening solution.
