  • 316 Stainless Steel Nuts

    316 Stainless Steel NutsDetailDimension Table

    316 stainless steel hex jam nuts are specialized fasteners with a reduced height compared to standard hex nuts. Jam nuts are thinner than standard hex nuts, making them suitable for applications where space is limited or where a low-profile nut is required. AYAINOX is manufactured to meet various international standards and specifications, such as ASME, DIN, ISO, and others.
