Value Collection JN9XX00800-050BX M8 Hex Nut 316 Ss Din 439B

Product Description

The VALUE COLLECTION JN9XX00800-050BX is an M8 x 1.25 hex nut manufactured from Grade 316 austenitic stainless steel (A4) with a bright, uncoated finish. Conforming to DIN 439B, this is a thin-style hex nut with a 13 mm across-flats width and a 4 mm height, making it well suited for low-profile fastening applications where standard-height nuts are not appropriate. The right-hand metric thread and corrosion-resistant 316 stainless construction make it a practical choice for plumbing, marine, chemical processing, and general industrial work. Licensed tradespeople and maintenance technicians use this fastener wherever stainless hardware is required to resist oxidation and chloride exposure.

This hex nut is used in residential and commercial applications that demand corrosion resistance and dimensional conformance to DIN 439B standards. Typical installation scenarios include pipe flange assemblies, equipment mounting on HVAC or plumbing systems, and structural connections in wet or chemically active environments. The M8 x 1.25 metric thread pitch is common across a wide range of European and metric-standard equipment, pumps, and valve assemblies encountered in the trades.

Key Features

• Grade 316 austenitic stainless steel (A4) for strong resistance to corrosion and chloride exposure
• Thin-profile DIN 439B design at 4 mm height for low-clearance fastening applications
• M8 x 1.25 right-hand metric thread for broad compatibility with metric hardware
• Bright, uncoated finish maintains dimensional accuracy and allows visual inspection
• 13 mm across-flats width fits standard metric wrenches and sockets

Compatibility

Designed as an OEM-style replacement or service fastener for metric-threaded assemblies requiring an M8 x 1.25 thin hex nut conforming to DIN 439B.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, electricians, or qualified maintenance personnel depending on the application. Ensure the mating bolt or stud is also M8 x 1.25 metric thread before assembly, and de-energize or isolate any system before servicing fasteners in pressurized or energized assemblies. Use a calibrated metric wrench or socket sized for 13 mm across flats. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or highly conductive environments where galvanic corrosion is a concern.
