Description

Meet the reliable fastening solution: Hex Head Cap Screws DIN 6921 8.8 Steel Plain M8-1.25 x 40. Built for strength and durability, these hex head cap screws meet the DIN 6921 standard and are crafted from high-tensile 8.8 steel with a plain (uncoated) finish for versatile use across projects.

Key specifications

  • Head type: Hex head
  • Material: 8.8 high-tensile steel
  • Finish: Plain (uncoated)
  • Thread: Metric coarse thread M8 x 1.25
  • Length: 40 mm
  • Standard: DIN 6921

Suitable applications

Designed for demanding assemblies in machinery, equipment, automotive, and general engineering projects. The 8.8 grade offers superior tensile strength for reliable clamping and long service life when paired with compatible nuts and washers.

Installation tips

Use a matching M8 nut and washer as needed. Tighten with a standard wrench or socket to the required torque per your engineering specifications. Ensure the threads are clean and free of debris to achieve optimal clamping force.

Plain steel screws are best in environments where coating is not required or where painting/coating is performed as part of the assembly. If corrosion protection is needed, consider applying a suitable coating or choosing a plated alternative.
