Reduced Shank Bolts and Screws with Coarse Thread - hexagon head bolts DIN 931/ISO 4014/GB 5782

——

Our Reduced Shank Hexagon Head Bolts and Screws with Coarse Thread are designed for straightforward and efficient assembly:

  • Standard Hex Head: Compatible with commonly used wrenches and sockets for easy tightening.
  • Coarse Thread: Offers quick engagement and strong holding power, suitable for high-speed assembly processes.
  • Clear Shoulder: The transition between the head/shank and the threaded portion is usually well-defined, ensuring proper seating and clamping.
  • Variety of Materials and Finishes: Available in various steel grades and surface treatments to meet specific automotive requirements for strength, corrosion resistance, and temperature tolerance.

Key Advantages for Your Applications:

  • Weight Savings: Contributes to overall vehicle weight reduction and improved fuel economy.
  • Potential Cost Reduction: Less material usage in the shank can lead to lower manufacturing costs.
  • Efficient Assembly: Easier initial alignment and faster thread engagement in some applications.
  • Strong Holding Power: The coarse thread provides reliable fastening and resistance to loosening.
  • Versatile Applications: Suitable for numerous non-critical alignment and fastening tasks where weight is a concern.
  • Standard Tooling: Can be installed using standard hex wrenches and sockets.

Ideal for:

  • Attaching Non-Structural or Secondary Components: Fastening plastic trims, interior panels, and lightweight brackets where full shank strength is not required.
  • Securing Components with Pre-Aligned Holes: Efficiently joining parts with precisely aligned holes where the shank primarily serves for guidance.
  • Applications Where Weight Reduction is a Key Design Goal: Contributing to the overall lightweighting efforts in modern vehicle design.
  • Certain Body Panel Attachments: Securing specific body panels or covers where a lighter fastener is sufficient.
  • Assembly Line Efficiency: The coarse thread facilitates faster initial engagement in high-volume production.
