Value Collection 812010PR Hex Lock Nut M4x0.7 Zinc

Product Description

The VALUE COLLECTION 812010PR is a metric hex lock nut with a nylon insert, designed to resist vibration-induced loosening in threaded fastener assemblies. Built to DIN 985 standards from Class 8 steel with a zinc finish, this nut provides corrosion resistance and reliable clamping force in moderate-load applications. The nylon insert engages the mating thread after the steel portion, creating prevailing torque that maintains joint integrity without secondary locking hardware. At M4x0.7 thread size, it is suited for compact assemblies where a low-profile, self-locking fastener is required. Plumbers, electricians, HVAC technicians, and mechanical contractors encounter these nuts in equipment panels, brackets, and component mounting across a wide range of trade installations.

This nut is appropriate for use in light to medium-duty mechanical assemblies, electrical enclosures, HVAC equipment brackets, pump and motor mounting hardware, and general industrial fastening applications. The zinc finish makes it suitable for dry or mildly corrosive indoor environments. Its DIN 985 compliance ensures dimensional consistency with metric hardware sourced from multiple manufacturers, making it a dependable choice for replacement or production fastening work.

Key Features

• Nylon insert locking style provides prevailing torque resistance against vibration loosening
• DIN 985 standard ensures metric dimensional compliance and cross-source interchangeability
• Class 8 steel construction delivers reliable strength for general-duty fastening
• Zinc finish provides corrosion protection in dry and mildly corrosive environments
• Right-hand thread direction for standard installation with common tooling
• 7.00 mm width across flats fits standard metric hex drivers and wrenches

Compatibility

Designed as a DIN 985-compliant metric hex lock nut for use with M4x0.7 threaded fastener assemblies across general mechanical, electrical, and HVAC equipment applications.

Installation Notes

Installation requires a standard metric hex wrench or socket sized for 7.00 mm across flats. The nylon insert is single-use by design and should not be reused once the nut has been fully torqued and removed, as the insert loses prevailing torque effectiveness after initial engagement. Ensure mating threads are clean and free of debris before assembly. Follow applicable mechanical or electrical codes for fastener torque requirements based on joint type and load conditions.
