Value Collection NL5X03000 Hex Lock Nut M30x3.5 316 Ss

Product Description

The VALUE COLLECTION NL5X03000 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade 316 A4 stainless steel with a bright uncoated finish, this fastener delivers corrosion resistance suitable for marine, chemical, and outdoor industrial environments. The M30x3.5 right-hand thread pattern conforms to DIN 985 standards. The nylon insert creates a prevailing torque locking action without requiring secondary locking hardware. Licensed tradespeople and maintenance crews working with large-diameter threaded assemblies will find this nut appropriate for structural and mechanical fastening applications.

This lock nut is used in heavy mechanical, structural, and industrial assembly applications where an M30x3.5 metric thread is specified and corrosion resistance is a priority. The Grade 316 A4 stainless steel construction makes it particularly well-suited for saltwater-exposed equipment, chemical processing hardware, and outdoor utility installations. It meets DIN 985 dimensional and performance standards, making it a direct fit where that fastener standard is called out on engineering drawings or maintenance documentation.

Key Features

• Nylon insert locking style provides prevailing torque resistance without additional hardware
• Grade 316 A4 stainless steel construction for superior corrosion resistance in harsh environments
• M30x3.5 right-hand thread, conforming to DIN 985 standard
• Bright uncoated finish — no galvanic coating that could affect dimensional tolerances
• 30 mm hex lock nut height and 46 mm width across flats for use with standard M30 tooling
• Single-piece packaging — order the exact quantity needed

Compatibility

Designed for use in any M30x3.5 metric threaded assembly where a DIN 985 nylon insert hex lock nut is specified. Verify thread pitch and standard compliance before installation.

Installation Notes

Installation requires an appropriately sized wrench or socket matched to the 46 mm width across flats. Power down or de-energize any connected equipment before working on mechanical assemblies. Do not reuse nylon insert lock nuts after full removal, as repeated cycling degrades the nylon insert and reduces prevailing torque effectiveness. Confirm thread engagement depth meets the requirements of the governing fastener specification or engineering drawing.
