Value Collection NL5X03300 Hex Lock Nut M33x3.5 316 Ss

Product Description

The VALUE COLLECTION NL5X03300 is an M33x3.5 hex lock nut with a nylon insert locking mechanism, manufactured from Grade 316 A4 stainless steel with a bright uncoated finish. The nylon insert compresses against the bolt thread to resist loosening caused by vibration and dynamic loads without requiring thread adhesives or secondary locking hardware. At 33.00 mm in height with a 50.00 mm width across flats, this nut meets DIN 985 dimensional and performance standards. It carries a right-hand thread direction and is suited for fastener applications demanding corrosion resistance in wet, marine, or chemically exposed environments. Licensed tradespeople and assembly professionals working with metric fastener systems will find this nut ready for direct installation.

This lock nut is appropriate for use in industrial, marine, plumbing, HVAC structural, and pool equipment applications where Grade 316 stainless steel is specified for superior chloride and corrosion resistance. The DIN 985 standard makes it compatible with metric bolt and stud assemblies requiring a prevailing-torque locking nut. It is commonly installed in applications where standard hex nuts cannot reliably maintain clamp load due to vibration, thermal cycling, or exposure to moisture and chemicals.

Key Features

• Nylon insert locking style provides prevailing-torque resistance without adhesives or separate locking hardware
• Grade 316 A4 stainless steel construction for superior corrosion and chloride resistance
• Meets DIN 985 fastener standard for consistent dimensional and mechanical performance
• Right-hand thread direction, M33x3.5 thread size
• Bright uncoated finish suitable for direct use in wet and chemically exposed environments
• 50.00 mm width across flats accepts standard metric hex tooling

Compatibility

Designed for use with M33x3.5 metric bolts and studs conforming to DIN 985 specifications in assemblies requiring a prevailing-torque nylon insert lock nut.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with metric fastener assemblies and applicable standards. Ensure the mating bolt or stud is clean and free of debris before threading the nut. Nylon insert lock nuts are generally rated for single use, as the insert can degrade with repeated removal and reinstallation, reducing locking effectiveness. Use an appropriate metric hex wrench or socket matching the 50.00 mm across-flats dimension to seat the nut properly.
