M8 x 40mm Hygienic Hex Head Screw | A4 Stainless Steel | EPDM Seal

This M8 x 40mm Hygienic Hex Head Screw is a practical choice for OEM builds that require a metric hygienic bolt with marine grade stainless steel and a seal beneath the head. With a 1.25mm pitch, 13mm across flats and A4 Stainless Steel construction, it suits OEM hygienic assemblies where consistent dimensions make repeat installation easier across manufactured units.

A4 stainless steel gives this fixing the corrosion resistance expected for exposed stainless equipment. EPDM is often selected where water resistance and ageing performance are important within hygienic production equipment. The 40mm length is suited to bespoke stainless frames and production enclosures, while the sealed head style helps support easier cleaning compared with exposed recess-style fixings.

Common Applications

  • Chemical washdown service areas
  • Washdown conveyor assemblies
  • Cleanroom furniture and access covers
  • Hygiene-sensitive machine maintenance
