Value Collection 621042PS M8x1.25 Coupling Nut 24mm

Product Description

The VALUE COLLECTION 621042PS is a metric coarse coupling nut designed to join two threaded rods or extend a bolt in a fixed assembly. Manufactured from steel with a zinc-plated finish for basic corrosion resistance, this fastener follows DIN 6334 standards and carries a right-hand M8x1.25 thread. The overall length of 24mm provides sufficient thread engagement for dependable load transfer in structural and mechanical connections. The 13mm width across flats allows installation with a standard metric wrench. Plumbers, electricians, millwrights, and general trade technicians reach for coupling nuts when rod hangers, threaded rod assemblies, or equipment mounting studs need to be lengthened or connected end-to-end.

This coupling nut is suited for use in light-duty to medium-duty threaded rod applications found in HVAC pipe and duct hanger assemblies, electrical conduit support systems, plumbing riser connections, and general fabrication work. The zinc plating makes it appropriate for dry or mildly humid indoor environments. It is not rated for submersion or corrosive chemical exposure. The M8x1.25 thread size is common across metric fastener hardware used in both residential and commercial mechanical systems.

Key Features

• M8x1.25 metric coarse right-hand thread for standard metric rod and bolt engagement
• DIN 6334 standard construction ensures consistent dimensional tolerancing
• Zinc-plated steel finish provides basic corrosion resistance for indoor applications
• 24mm overall length delivers adequate thread engagement for secure rod coupling
• 13mm width across flats accepts standard metric combination or box-end wrenches

Compatibility

Designed as a standard DIN 6334 metric coupling nut compatible with M8x1.25 metric coarse threaded rod and fasteners used in HVAC, plumbing, and electrical support assemblies.

Installation Notes

Installation requires a metric wrench sized to 13mm across flats. Ensure mating threaded rod or bolt stock is M8x1.25 metric coarse before assembly to avoid cross-threading. Thread both ends of the coupling nut fully onto each rod end until the desired engagement depth is reached, and verify the joint is snug before applying load. This fastener is intended for indoor or sheltered installations; use stainless or hot-dip galvanized hardware in corrosive or outdoor environments.
