Value Collection DN7XX00300-050BX M3x0.5 Acorn Nut

Product Description

The VALUE COLLECTION DN7XX00300-050BX is an M3x0.5 metric coarse stainless steel acorn nut designed to cap and protect exposed thread ends while providing a finished appearance. Manufactured from Austenitic A4 stainless steel, this nut offers strong resistance to corrosion and is well suited for wet, coastal, or chemically active environments. It measures 5.5mm width across flats and stands 5.1mm overall in height. The uncoated finish keeps the natural stainless surface intact. Produced to DIN 1587 standards, it is a dependable choice for metric fastener assemblies requiring both thread protection and reliable clamping performance.

This acorn nut is used in light mechanical assemblies, plumbing fixture mounting, HVAC panel work, pool and spa equipment enclosures, and any application where an M3x0.5 right-hand threaded fastener must be capped or secured. The A4 stainless grade makes it appropriate for outdoor installations and marine-adjacent environments where standard carbon steel hardware would corrode. It is commonly specified by technicians, fabricators, and field service professionals working with metric fastener systems.

Key Features

• M3x0.5 metric coarse right-hand thread for compatibility with standard metric assemblies
• Austenitic A4 stainless steel construction for corrosion resistance in harsh environments
• Meets DIN 1587 standard for acorn nut geometry and thread engagement
• 5.5mm width across flats for use with standard metric wrenches and sockets
• 5.1mm overall height provides adequate dome clearance for exposed thread protection
• Uncoated finish retains natural stainless surface with no risk of coating delamination

Compatibility

Designed as a DIN 1587 standard replacement or new-installation acorn nut for any M3x0.5 metric coarse threaded stud, bolt, or rod in residential or light commercial applications.

Installation Notes

Installation is performed by hand or with a 5.5mm metric wrench or socket. Shut down or de-energize any equipment before accessing fastener locations on mechanical or electrical assemblies. Do not over-torque stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.
