General Description

DIN 912 A4 M24 x 90 screws are hex head screws designed for applications requiring high corrosion resistance and strength. This type of screw is commonly used in industrial and structural environments, where durability and strength are crucial.

Technical Specifications

• Brand and Model : DIN 912 A4 M24 x 90
• Screw Type : Hex Head Screw
• Standard : DIN 912
• Material : A4 stainless steel, which offers excellent resistance to corrosion and rust.
• Dimensions:
  • Diameter : M24 (24mm diameter)
  • Length : 90 mm
  • Thread Pitch : Standard for M24 diameter

Construction and Components

• Hex Head : Allows the use of hex keys for safe and precise tightening.
• Threading : Precision threading to ensure a tight fit and secure seal.
• Body : Robust design, resistant to traction and compression.

Usage Procedure

1. Preparation:

   • Make sure the hole where the screw will be inserted is clean and free of debris.
   • Use an appropriately sized hex wrench for tightening.

2. Installation:

   • Insert the screw into the threaded hole.
   • Use the hex key to tighten the screw until the desired torque is achieved.

3. Verify:

   • Check the tightening to ensure that the screw is tightened properly and that there is no looseness.

Matching accessories

• Nuts : Internal hexagon nuts compatible with M24 thread.
• Washers : Flat or lock washers to distribute force and prevent loosening.
• Lubricants : Anti-corrosion lubricants to improve screw life and facilitate tightening.

Mathematical Formulas for Optimal Use

• Torsional Moment Calculation:

  $$T$$

  Where TT $T$ is the torque, FF $F$ is the applied force and rr $r$ is the radius of the screw head.

• Tensile Strength:

  $$R$$

  Where RR $R$ is the tensile strength, FmaxF_{max} $F$ ma x ​is AA $A$ is the cross-sectional area of ​​the screw.

Compatible Materials

DIN 912 A4 M24 x 90 screws can be used with:

• Metals : Steel, aluminum, etc.
• Plastic Materials : Reinforced nylon, polyurethane, etc.
• Others : Structural and composite materials.

Maintenance

• Periodic Inspection : Check screws regularly for signs of wear or corrosion.
• Cleaning : Clean the screws to remove any debris and surface corrosion.
• Tightening : Check and tighten screws periodically to ensure a secure fit.

Evaluation of used cars

To assess whether a DIN 912 A4 M24 x 90 screw is in good condition:

• Visual Inspection : Check for signs of corrosion, thread damage, or deformation.
• Thread Check : Make sure the thread is intact and not worn.
