Value Collection NL5X02700-010BX M27x3 Hex Lock Nut Din 985

Product Description

The VALUE COLLECTION NL5X02700-010BX is an M27x3 hex lock nut with a nylon insert locking mechanism, manufactured from Class 316/A4 stainless steel with a bright, uncoated finish. The nylon insert deforms against the mating thread under assembly torque, creating a prevailing-torque lock that resists loosening from vibration and shock loads without requiring secondary locking hardware. At 41.00 millimeters across the flats and 27.00 millimeters in height, this nut is dimensioned to DIN 985 standards. It is suited for corrosion-resistant fastening applications where stainless steel alloy selection is required for environmental exposure or material compatibility.

This hex lock nut is used in industrial, marine, plumbing, and mechanical assembly applications where vibration resistance and corrosion resistance must be maintained simultaneously. The 316/A4 stainless steel grade provides elevated resistance to chlorides and other corrosive media compared to standard 304/A2 grades, making it appropriate for coastal, chemical-exposure, and wet-service environments. Right-hand thread direction follows standard fastener convention. Tradespeople, millwrights, pipefitters, and marine maintenance technicians commonly install this fastener type.

Key Features

• Nylon insert locking style provides prevailing-torque resistance without secondary hardware
• Class 316/A4 stainless steel construction for superior corrosion resistance in harsh environments
• M27x3 thread size with right-hand thread direction per standard fastener convention
• 41.00 mm width across flats, 27.00 mm height — dimensioned to DIN 985
• Bright, uncoated finish — no plating or coating to degrade or delaminate
• Conforms to DIN 985 fastener standard

Compatibility

Designed for use with M27x3 metric threaded fasteners and bolts. Suitable as a standard DIN 985 hex lock nut replacement or new installation on any M27x3 threaded assembly requiring a nylon insert prevailing-torque nut.

Installation Notes

Install using a standard metric hex wrench or socket sized to 41.00 mm across the flats. The nylon insert is single-use by design — remove and discard any nylon insert lock nut that has been fully run down and unthreaded, as the insert loses its prevailing-torque effectiveness after initial use. Ensure mating bolt threads are clean and free of burrs before assembly. Follow applicable mechanical or structural fastening codes for torque sequences in the specific application.
