Value Collection 1-MC-5 Acorn Nut M5x0.8 Stainless Steel

Product Description

The VALUE COLLECTION 1-MC-5 is a stainless steel acorn nut with M5x0.8 metric coarse threading intended for fastening applications that require a clean, closed-end profile. The domed cap covers the exposed thread end, protecting both the fastener and surrounding components from corrosion and contact damage. Manufactured from austenitic A2 stainless steel, this nut resists rust and oxidation in wet or chemically active environments. The 8mm width across flats suits standard metric wrenches and sockets. Overall height is 10mm. Plumbers, HVAC technicians, electricians, and general tradespeople use this style of nut wherever an uncoated, corrosion-resistant finish is preferred over plated hardware.

This acorn nut is suited for use in residential and light commercial mechanical assemblies where an exposed thread end is undesirable. Typical applications include equipment enclosures, panel hardware, pipe supports, and any structural or mechanical joint requiring a finished-looking fastener. The uncoated A2 stainless steel finish makes it appropriate for outdoor installations, damp locations, and environments where zinc-plated hardware would corrode prematurely. It conforms to DIN 1587, a widely recognized dimensional standard for acorn nuts.

Key Features

• M5x0.8 metric coarse right-hand thread for standard metric fastening applications
• A2 austenitic stainless steel construction for corrosion resistance in wet and outdoor environments
• Closed domed cap profile protects exposed thread ends from damage and contact
• 8mm width across flats fits standard metric wrenches and sockets
• 10mm overall height per DIN 1587 dimensional standard
• Uncoated finish — no plating to chip, flake, or interact with dissimilar metals

Compatibility

Designed as a standard DIN 1587 acorn nut for use with M5x0.8 metric coarse threaded fasteners and mating hardware in mechanical, electrical, and plumbing assemblies.

Installation Notes

Installation requires a standard 8mm metric wrench or socket. Verify that the mating bolt or stud carries M5x0.8 metric coarse threading before torquing to avoid cross-threading. Stainless-on-stainless fastener pairs can be prone to galling — apply an appropriate anti-seize compound when threading A2 hardware onto stainless studs or bolts. Shut down and de-energize any equipment before servicing fasteners on live panels or energized assemblies.
