Value Collection JN9X00800-100BX M8 Hex Nut 18-8 Ss Din 439B

Product Description

The VALUE COLLECTION JN9X00800-100BX is a metric hex nut designed for general fastening applications requiring corrosion resistance and dimensional accuracy. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this nut meets DIN 439B standards, which specify a thin-profile hex nut geometry. The M8 x 1.25 thread size and 13 mm across-flats dimension make it a common choice in mechanical assemblies, equipment fabrication, and plumbing or HVAC bracket work where stainless hardware is specified to resist rust and chemical exposure. Installation requires no special coating or preparation beyond standard torque practice.

This hex nut suits light clamping and low-profile fastening tasks in residential and commercial mechanical systems. Its thin-profile DIN 439B form is commonly used as a jam nut or in applications with limited axial clearance. Fabricators, pipefitters, HVAC technicians, and general mechanical contractors working with metric hardware will find this nut compatible with standard M8 x 1.25 threaded rod, bolts, and studs. The 18-8 stainless grade provides adequate corrosion resistance for indoor and moderate outdoor environments without additional surface treatment.

Key Features

• 18-8 stainless steel construction provides corrosion resistance without a surface coating
• DIN 439B thin-profile hex nut standard ensures consistent dimensional tolerances
• M8 x 1.25 metric thread with right-hand thread direction
• 13 mm across-flats width fits standard metric wrenches and sockets
• 4 mm height suits low-profile and jam-nut fastening configurations
• Bright, uncoated finish — no risk of coating separation or galvanic interference from plating

Compatibility

Designed for use with any M8 x 1.25 right-hand threaded fastener including bolts, screws, and threaded rod conforming to metric DIN or ISO standards.

Installation Notes

A licensed mechanic, fabricator, or qualified tradesperson should verify thread engagement meets minimum depth requirements before final torque. Power down or de-energize any equipment before accessing fastener locations on energized panels or mechanical assemblies. Use a standard 13 mm metric wrench or socket; avoid impact tools at final seating to prevent thread galling on stainless fasteners. When used as a jam nut, tighten against the primary nut in the standard back-to-back technique to lock the assembly.
