Value Collection NL5X00250-050BX Hex Lock Nut M2.5x0.45 Din 985 50pk

Product Description

The VALUE COLLECTION NL5X00250-050BX is an M2.5x0.45 hex lock nut with a nylon insert, manufactured from 18-8 A2 stainless steel with a bright uncoated finish. The nylon insert collar deforms around mating threads under torque, creating prevailing-torque resistance that resists loosening from vibration and thermal cycling. This fastener meets DIN 985 dimensional and performance standards. It is used in light-duty mechanical assemblies, enclosures, and equipment panels where corrosion resistance and reliable thread locking are required. The package contains 50 individual nuts. Minimum order quantity is 50 units.

This nut is suited for small-fastener applications in HVAC controls, electrical enclosures, instrumentation, and general mechanical assemblies requiring metric M2.5 hardware. The 18-8 A2 stainless steel construction makes it appropriate for mildly corrosive environments or installations where zinc-plated carbon steel hardware is not acceptable. Right-hand thread direction matches standard metric bolt and stud pairings at this size. Installers working to DIN or ISO fastener specifications will find this nut dimensionally compliant for those applications.

Key Features

• Nylon insert locking style provides prevailing-torque resistance without adhesive compounds
• 18-8 A2 stainless steel construction resists corrosion in mildly aggressive environments
• Meets DIN 985 dimensional and performance standard
• Right-hand thread direction, M2.5x0.45 pitch
• Bright uncoated finish — no additional coating to affect thread fit or tolerance
• Sold in a box of 50 units per package

Compatibility

Designed for use with M2.5x0.45 right-hand threaded metric bolts and studs conforming to DIN or ISO metric fastener standards. Dimensionally compliant per DIN 985.

Installation Notes

Nylon insert lock nuts are intended for single-use applications — the nylon collar loses prevailing-torque effectiveness after removal and should not be reused in critical joints. Installation requires no special tools beyond an appropriately sized wrench or nut driver for the 4.00 mm across-flats dimension. De-energize and lock out any equipment before accessing fastener locations in electrical or control panel assemblies. Do not apply thread-locking adhesive to nylon insert lock nuts, as the insert already provides the locking function.
