Screws for the hydraulic sector

Our range of screws mainly includes CHC Screws (Cylindrical Hexagon Socket Head Screws) and TH Screws (Hexagonal Head Screws), which are commonly used in industrial applications, especially for the assembly of hydraulic components, fastening mechanical parts under pressure, and in environments requiring robust and reliable connections.

Types of screws we offer

Hexagon Socket Head Cap Screws (CHC)

These screws are generally used for mechanical assemblies in environments requiring high resistance, particularly in high-pressure hydraulic systems. They are available in various lengths and grades (12.9, 8.8), making them ideal for the assembly of hydraulic cylinders, pumps, and hydraulic manifolds.

Examples:

• CHC Screw M5x90 brut 12.9: Used for high mechanical strength fastenings in pressure systems.
• CHC Screw M8x120 zinc-plated 8.8: Used in applications where corrosion resistance is important, such as outdoor environments or humid conditions.

Hexagonal Head Screws (TH)

TH screws, available in grades 8.8 and 10.9, are often used for assemblies requiring high torque and increased strength. They are ideal for hydraulic environments where parts must be securely and durably fastened.

Examples:

• TH Screw M10x200 BR 10.9: For hydraulic applications requiring robust connections under high pressure.
• TH Screw M6x12 zinc-plated 8.8: Used in humid environments or those prone to corrosion.

Cylindrical Button Head Screws (TCB)

These screws have a slightly domed cylindrical head, providing a clean finish and uniform pressure distribution on the fastening surface. They can also be referred to as button head screws or TCB screws.

Screws and applications in the hydraulic sector

Screws such as TH screws (Hexagonal Head), TCB screws (Cylindrical Button Head), and CHC screws (Cylindrical Hexagon Socket Head) are used in a variety of hydraulic components and systems, often subjected to high-pressure conditions and requiring robust fastenings. Here are some concrete applications, hydraulic components where these screws are used, as well as related fields and equipment:

Concrete applications in hydraulic components

• Hydraulic cylinders
  CHC and TH screws are used to assemble the various parts of the cylinder (end cap, piston, rod, etc.), ensuring a strong and pressure-resistant fastening in high-stress environments.

• Hydraulic pumps:
  TCB and CHC screws are often used to secure pump covers, hold seals in place, and ensure tightness under high pressure.

• Hydraulic distribution blocks (manifolds):
  These blocks require CHC screws to fasten control plates and maintain the various oil passages securely under high pressure.

• Hydraulic collectors:
  CHC and TH screws are used to secure distribution tubes and fittings on collectors, allowing smooth hydraulic fluid circulation.

• Hydraulic valves:
  Directional or proportional valves in hydraulic systems are often assembled using TH or CHC screws, ensuring precision and shock resistance in industrial environments.

Hydraulic sectors where these screws are used

Construction

• Construction equipment like excavators, bulldozers, wheel loaders, or hydraulic cranes use hydraulic systems for articulated arms, stabilizers, and other mechanisms where these screws play a key role in assembling and securing components under pressure.

Agriculture

• Tractors, combine harvesters, and other agricultural equipment use hydraulic systems to lift, tilt, or adjust heavy tools. CHC and TH screws are often used to assemble cylinders and pumps that drive these mechanisms.

Transportation and logistics:

• Dump trucks, forklifts, and aerial work platforms use hydraulic cylinders and lifting systems where TH and CHC screws are essential for keeping components functional under high pressure.

Mining industry

• Hydraulic drills, crushers, and other heavy machinery used in the mining industry rely on complex hydraulic systems that require sturdy fastenings with CHC and TH screws to ensure durability and safety in harsh environments.

Marine sector

• Hydraulic systems on fishing boats, container ships, or port cranes use zinc-plated or stainless steel screws (anti-corrosion) to withstand corrosive marine environments.

Manufacturing industry

• Hydraulic presses, machine tools, and industrial robots require hydraulic components to actuate precise movements, with CHC and TH screws ensuring the systems' robustness.

Equipment using these screws

• Hydraulic excavators
• Agricultural tractors
• Forklifts
• Dump trucks
• Construction cranes
• Aerial work platforms
• Mining vehicles
• Fishing boats and ships
• Industrial hydraulic presses

These screws, depending on their type and material, are used in critical applications where robustness, durability, and corrosion resistance are essential to ensure the proper performance of hydraulic systems under high pressure.

Zinc-plated (anti-corrosion) screws

Zinc-plated screws are treated to resist corrosion, making them perfect for environments exposed to moisture, such as marine or outdoor hydraulic systems.

Examples:

• CHC Screw M10x90 zinc-plated 8.8: Suitable for outdoor fastenings with good corrosion resistance.
• CHC Screw M8x70 zinc-plated 8.8: Ideal for systems exposed to the elements.

Fastenings for small components

Smaller screws, such as CHC Screw M5x30 zinc-plated 8.8, are often used to assemble small components in hydraulic systems or to fasten light parts in demanding environments.
