Part Threaded Design
The plain shank provides an unthreaded section between the head and threaded end. Select the bolt length to suit the assembly thickness and required thread engagement, ensuring the shank does not prevent the joint from tightening correctly.
The listing specifies a 28mm threaded section. If the exact thread or shank length is critical, confirm the dimensions of the selected size before ordering.

Typical Applications
Suitable for machinery, brackets, equipment maintenance and outdoor or coastal assemblies where A4 stainless steel is appropriate to the service conditions.
Installation
Use compatible M8 x 1.25mm nuts or tapped holes. Check thread engagement, shank length and head clearance before installation. Tighten with a correctly fitting 6mm Allen key and a torque appropriate to the joint and lubrication conditions.
Suitable lubrication and controlled installation speed can help reduce the risk of galling when assembling stainless steel threads.
