Value Collection BDNA-A410002 M4 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION BDNA-A410002 is a fully threaded hex head cap screw manufactured from Grade 316 Austenitic Grade A4 stainless steel in a metric M4 x 0.70 thread profile with a 10 mm length under the head. The 7 mm hex drive and DIN 933 standard geometry make this screw a direct fit for metric fastening applications where dimensional consistency and corrosion resistance are required. Grade 316 stainless provides elevated resistance to chlorides and oxidizing environments compared to 304 alloys, making it a preferred choice in marine, chemical, and outdoor service conditions. The uncoated finish maintains dimensional integrity and avoids coating thickness variation on close-tolerance assemblies.

This screw is suited for light-duty metric fastening in HVAC equipment panels, plumbing fixture mounting, electrical enclosures, pool and spa equipment, and general industrial assemblies. The fully threaded shank allows engagement along the entire fastener length, which is advantageous when threading into shallow bosses or thin material. It is appropriate for both original equipment assembly and field repair work performed by licensed trades or experienced maintenance technicians.

Key Features

• Grade 316 Austenitic Grade A4 stainless steel for superior corrosion resistance in wet and chloride-exposed environments
• M4 x 0.70 metric thread, fully threaded per DIN 933 standard
• 7 mm hex drive for standard metric wrench or socket engagement
• 10 mm length under head suits shallow-boss and thin-panel fastening applications
• Uncoated finish preserves dimensional accuracy on close-tolerance metric assemblies

Compatibility

Designed as a metric DIN 933 hex head cap screw for general fastening applications requiring an M4 x 0.70 thread form in Grade 316 stainless steel.

Installation Notes

Installation is appropriate for any qualified technician or tradesperson performing metric fastener work. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated clamp load for M4 Grade A4 hardware; overtightening small-diameter stainless fasteners can cause galling or thread seizure. Use of an anti-seize compound is advisable when threading stainless steel into stainless steel mating components.
