Value Collection DN7X00400-050BX M4x0.7 Acorn Nut

Product Description

The VALUE COLLECTION DN7X00400-050BX is a metric coarse stainless steel acorn nut designed to cap and protect threaded fastener ends while providing a finished appearance. Sized for M4x0.7 threads with a 7mm width across flats and an 8mm overall height, this nut is manufactured to DIN 1587 standards from A2 austenitic stainless steel. The uncoated finish exposes the natural corrosion resistance of the stainless alloy. It is suitable for use by mechanics, electricians, plumbers, HVAC technicians, and maintenance professionals working in environments where a capped fastener end is required.

This acorn nut is used in applications requiring a domed, closed-end nut that prevents thread exposure and protects against contaminants, debris, and incidental contact. The M4x0.7 metric coarse thread sizing makes it a common hardware choice in panel assembly, equipment enclosures, light mechanical fixtures, and general trade maintenance work. The A2 stainless steel construction suits indoor and moderate outdoor environments where corrosion resistance is needed without the cost of A4 marine-grade material.

Key Features

• M4x0.7 metric coarse right-hand thread for broad fastener compatibility
• 7mm width across flats for standard metric wrenches and sockets
• 8mm overall height with domed acorn profile to cap and protect thread ends
• A2 austenitic stainless steel construction for corrosion resistance
• Uncoated finish — no plating to flake or degrade in service
• Manufactured to DIN 1587 standard for dimensional consistency

Compatibility

Designed for use with M4x0.7 metric coarse threaded fasteners and bolt ends requiring a closed-end acorn-style nut per DIN 1587 dimensional requirements.

Installation Notes

Install using a metric wrench or socket sized for 7mm width across flats. Hand-start the nut onto the mating thread before applying tool torque to avoid cross-threading. Power down or de-energize any equipment before working on fasteners in electrical or control enclosures. Do not exceed the thread engagement limits of the mating fastener material when applying torque.
