Value Collection JN9XX01600-010BX Hex Nut M16 X 2

Product Description

The VALUE COLLECTION JN9XX01600-010BX is a metric hex nut machined from Grade 316 austenitic stainless steel, classified as Austenitic Grade A4. It carries an M16 x 2 thread specification with a right-hand thread direction and conforms to the DIN 439B fastener standard. The nut measures 24 mm across the flats and 8 mm in height, delivered in a bright, uncoated finish. This hardware is used wherever corrosion resistance is critical, making it a standard choice for marine, chemical processing, food service, and outdoor structural applications. Installation is performed by maintenance mechanics, millwrights, pipefitters, and general trade professionals working with metric fastener systems.

This hex nut is suited for bolted connections in corrosive or wet environments where carbon steel fasteners are not appropriate. The Grade 316 alloy provides enhanced resistance to chloride-induced corrosion compared to Grade 304, making it particularly relevant in coastal installations, process piping flanges, pool equipment enclosures, and stainless fabrication work. The DIN 439B profile indicates a thin or flat hex nut geometry, which is appropriate for low-profile fastening applications and jam-nut configurations.

Key Features

• Grade 316 austenitic stainless steel (Austenitic Grade A4) for superior corrosion resistance
• M16 x 2 metric thread, right-hand direction
• Conforms to DIN 439B fastener standard for consistent dimensional control
• Bright, uncoated finish — no coating to flake, chip, or affect thread fit
• Thin hex nut profile suitable for jam-nut and low-clearance applications
• 24 mm across flats, compatible with standard metric wrenching tools

Compatibility

Designed for use with M16 x 2 metric threaded fasteners in applications requiring DIN 439B thin hex nut geometry. Suitable for pairing with Grade 316 or Grade A4 stainless bolts and studs to maintain galvanic compatibility.

Installation Notes

Installation is performed by hand-threading onto the mating bolt or stud, then torquing with a 24 mm open-end or box wrench. When used as a jam nut, seat the primary nut first and apply the jam nut against it. Avoid mixing stainless fastener grades with dissimilar metals in highly conductive or submerged environments to minimize galvanic corrosion risk. Anti-seize compound is recommended for stainless-to-stainless thread engagement to prevent galling during assembly.
