Galvanized Timber Bolt (HDG Bolt):

A Galvanized Timber Bolt, also known as an HDG (Hot-Dipped Galvanized) Bolt, is a specialized type of timber bolt crafted from steel that has undergone the hot-dip galvanization process. This process involves coating the bolt with a thick layer of zinc to protect against corrosion, making it ideal for use in harsh environmental conditions.

Key Features:

• Material: Made from hot-dipped galvanized steel, which provides superior corrosion resistance and durability.
• Design: Timber bolts typically feature a dome-shaped head and a wide, textured underhead area that prevents turning when tightened against wood. This design is particularly useful for securing large wooden planks and structural components.
• Applications:
  • Outdoor Wood Construction: Ideal for building decks, bridges, and other outdoor structures where longevity and strength are crucial.
  • Marine Construction: Used in docks, piers, and other marine applications where exposure to water necessitates extra protection against corrosion.
  • Special Applications: Suitable for any construction requiring robust fastening solutions and enhanced resistance to environmental factors.

Common Uses:

• Timber bolts are particularly effective in securing large wooden structures, offering both aesthetic appeal and functional stability. They are designed to handle heavy loads and provide a reliable fastening solution that enhances the structural integrity of wood constructions.

 

Bent Anchor Bolts

Bent Anchor Bolts, also known as 90-degree anchor bolts, are heavy-duty fasteners used to attach objects or structures to concrete. They are L-shaped and have a bent portion that creates resistance to prevent the bolt from pulling out of the concrete when force is applied.

Key Features:

• Design: The L-shaped design of bent anchor bolts provides a secure hold by creating resistance within the concrete, ensuring the bolt remains in place even under significant force.
• Material: Typically made from high-strength steel, these bolts offer durability and reliability in various heavy-duty applications.
• Resistance: The bent portion of the bolt adds extra resistance against pull-out forces, making them ideal for applications requiring increased load support.

Applications: Bent anchor bolts are commonly used in construction and engineering for applications that require increased load support, such as:

• Anchoring structural columns
• Light poles
• Bridge rails
• Signage
• Embed plates
• Floor plates

Available Sizes:

• 3/8-16

• 3/4-10

 

Carriage Bolts

A carriage bolt, also known as a coach bolt, plow bolt, or cup head bolt, is a heavy-duty, threaded fastener with a round head, square neck, and shallow dome shape. They are valued for their strength and durability and are commonly used in wood applications, but can also fasten metal, plastic, or two pieces of wood together.

Key Features:

• Design: Carriage bolts feature a round head with a shallow dome and a square neck that prevents the bolt from turning once tightened.
• Material: Typically made of high-strength materials, they are designed to withstand heavy-duty applications.

Applications:

• Wood: Ideal for outdoor applications like building decks and fences, especially in marine or coastal environments where saltwater corrosion is a concern. The square neck of the bolt pulls into the wood as the nut is tightened, creating a secure fit.
• Metal: The square neck of the bolt prevents it from spinning while the nut is fastened, making it ideal for security applications like locks and hinges. Carriage bolts can also be used in flatpack metal constructions like industrial racking or furniture, where a square recess is cut to stop the bolt from spinning.
• Other: Carriage bolts can also be used to fasten wood to metal or two separate metal components, providing versatility in various construction and assembly projects.

Available Sizes:

• Imperial Sizes: From 6-32 to 7/8-9
• Metric Sizes: From M5-0.8 to M12-1.75
