Certified Hygienic
Bolts
NGI can offer certified hygienic BXH bolts with blue sealings. The sealing blocks out water and bacteria and prevents a non-hygienic metal-to-metal assembly.
The bolts have self-draining surfaces with a maximal roughness of 0.8 μm Ra. The design of the bolts does not deviate from the sizes of current standard bolts. Therefore, wrench sizes, thread heights, etc. all remain the same making it very easy to upgrade and replace standard bolts.
These are the right bolts to be used on all machinery in all certified hygienic wash-down environments.
