Value Collection NL5X01200-050BX M12x1.75 Hex Lock Nut 50pk

Product Description

The VALUE COLLECTION NL5X01200-050BX is a nylon insert hex lock nut designed to maintain clamping force in applications subject to vibration, thermal cycling, or repeated mechanical stress. Manufactured from 18-8/A2 stainless steel with a bright, uncoated finish, it provides solid corrosion resistance in wet, outdoor, and mildly chemical environments. The M12x1.75 right-hand thread and 19.00 mm width across flats conform to DIN 985 standards, making this a direct fit wherever DIN-spec fasteners are specified. Height is 12.00 mm. Sold in a minimum order quantity of 50 per purchase.

This nut is suited for general industrial, mechanical, and structural assembly work where a prevailing-torque locking fastener is required. The nylon insert deforms around mating threads on installation, creating a friction lock that resists loosening without requiring adhesives, lock washers, or secondary locking hardware. Common applications include equipment frames, pipe supports, HVAC mounting brackets, electrical enclosure hardware, and plumbing fixture assemblies where stainless steel fasteners are preferred for corrosion resistance.

Key Features

• M12x1.75 right-hand thread, DIN 985 standard compliant
• 18-8/A2 stainless steel construction for corrosion resistance in wet and outdoor environments
• Nylon insert locking mechanism resists vibration-induced loosening without secondary hardware
• 19.00 mm width across flats fits standard metric hex tooling
• 12.00 mm nut height provides adequate thread engagement for M12 bolt applications
• Bright, uncoated finish maintains dimensional accuracy and is compatible with stainless fastener assemblies

Compatibility

Designed as a DIN 985 compliant nylon insert hex lock nut for use with M12x1.75 metric fastener assemblies in applications requiring prevailing-torque locking.

Installation Notes

Installation is performed with a standard metric hex wrench or socket sized for 19.00 mm across flats. The nylon insert is a single-use locking element and the nut should be replaced if removed and re-torqued in critical applications. Do not exceed the rated torque for M12 stainless fastener assemblies, and consult relevant fastener standards for torque specifications appropriate to the joint design. Stainless steel fasteners are susceptible to galling — apply appropriate anti-seize compound to mating threads where galling risk is elevated.
