Value Collection NL5XX00500-050BX M5x0.8 Hex Lock Nut 50pk

Product Description

The VALUE COLLECTION NL5XX00500-050BX is a metric hex lock nut with a nylon insert locking mechanism, manufactured from Class 316 / A4 stainless steel with a bright, uncoated finish. Sized at M5x0.8 with a right-hand thread direction, it meets DIN 985 standards for prevailing-torque hex lock nuts. The nylon insert deforms around mating threads to resist loosening under vibration and dynamic loads without damaging the fastener. Licensed trades and maintenance technicians use these in applications requiring corrosion resistance and reliable locking. This listing covers a minimum order of 50 pieces.

These lock nuts are suited for marine, food processing, chemical processing, and outdoor structural assemblies where 316-grade stainless is specified for chloride and corrosion resistance. The M5x0.8 thread pitch is common in light mechanical assemblies, panel mounting, and equipment fabrication. The DIN 985 standard ensures consistent dimensional interchangeability with metric hardware sourced from multiple suppliers. Installation requires no adhesive or deforming tool — the nylon collar provides the prevailing torque on engagement.

Key Features

• Nylon insert locking style resists vibration-induced loosening without thread damage
• 316 / A4 stainless steel construction provides superior corrosion resistance in wet and chloride-rich environments
• Meets DIN 985 dimensional and performance standards for metric prevailing-torque nuts
• Bright, uncoated finish maintains dimensional tolerances and is compatible with standard M5 tooling
• Right-hand thread direction — standard engagement with all conventional M5x0.8 bolts and studs

Compatibility

Designed for use with standard M5x0.8 metric bolts, screws, and threaded rod conforming to DIN or ISO metric thread standards.

Installation Notes

Install using an 8 mm wrench or socket; no thread-locking compound is required. Nylon insert lock nuts are single-use — once fully engaged and removed, the insert loses prevailing-torque effectiveness and the nut should be replaced. Ensure mating fastener threads are clean and free of burrs before engagement. Follow applicable mechanical and structural codes for fastener selection in load-bearing applications.
