Value Collection HN4XX00400-100BX Hex Nut M4 X 0.70 316 Ss

Product Description

The VALUE COLLECTION HN4XX00400-100BX is an M4 x 0.70 metric hex nut manufactured from Grade 316 austenitic stainless steel, designated Grade A4 under the DIN classification system. This nut features a bright, uncoated finish and a right-hand thread direction, conforming to the DIN 934 fastener standard. At 7 mm across the flats and 3.20 mm in height, it is sized for M4 threaded assemblies requiring corrosion-resistant hardware. The Grade 316 alloy provides elevated resistance to chlorides and marine or chemical environments, making it a common choice for plumbing, HVAC, and industrial mechanical assemblies where standard carbon steel fasteners would corrode prematurely.

This hex nut is suited for metric threaded applications across residential and commercial trade work, including pipe flange connections, equipment mounting, and panel assembly in corrosive or wet environments. The M4 thread size is common in light mechanical and electrical enclosure applications. Sold in a minimum order quantity of 100 units per box, this SKU is practical for contractors and service technicians who require consistent hardware stock for ongoing service or installation projects.

Compatibility

Designed as a DIN 934-compliant replacement or stock hex nut for M4 x 0.70 metric threaded fastener applications in plumbing, HVAC, electrical enclosure, and general mechanical assemblies requiring Grade 316 stainless steel hardware.

Installation Notes

Installation is performed by hand-threading onto any M4 x 0.70 metric male fastener, then tightening with a 7 mm wrench or socket. Confirm thread direction is right-hand before assembly. In corrosive or submerged environments, avoid mixing metals that may cause galvanic corrosion with the Grade 316 stainless steel. Power down or de-energize any electrical equipment before working in enclosures where these fasteners are used.
