Description
Overview
DIN961 defines the standard dimensions for fully threaded fine pitch bolts, ensuring interchangeability and reliable engineering performance.
This selected size is specified with diameter M16, length 30 mm, thread M16, pitch 1.5 mm.
Sold in multiples of '50 pieces. 1 Box = '50 pieces.
Material, Grade & Strength
Grade 8.8 offers approximately 800 MPa tensile strength and 640 MPa yield strength.
Finish & Corrosion Protection
Plain finish is intended for protected indoor applications.
Typical Uses
Used in machinery, fabrication, mining, agriculture, maintenance and general engineering.
Technical Tips
- Use matching mating components.
- Follow recognised torque specifications.
- Select the correct material and finish for the operating environment.
