Value Collection 823012PS M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 823012PS is an M3x0.5 flat socket cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. The screw features a 90-degree flat head and a hex socket drive, conforming to DIN 7991. It is fully threaded at 16 mm overall length. This fastener is installed by machinists, maintenance technicians, and assembly professionals who require a flush or countersunk seating profile in metric-threaded applications where corrosion resistance is a priority.

This screw is suited for light-duty mechanical assemblies, equipment enclosures, and precision fabrications where the fastener head must sit flush with or below the mating surface. The metric thread standard and DIN 7991 specification make it a common choice in industrial, marine, and food-processing environments where stainless steel is required to resist oxidation and chemical exposure. It is sold in multiples of 50 units minimum.

Key Features

• 90-degree flat head seats flush or countersunk for a clean, low-profile finish
• Hex socket drive accepts a 2 mm hex key for precise torque application in confined spaces
• 18-8 austenitic Grade A2 stainless steel resists corrosion and oxidation without a coating
• Fully threaded along the 16 mm overall length for maximum thread engagement
• Conforms to DIN 7991 for dimensional consistency with metric fastener systems
• Bright, uncoated finish maintains dimensional tolerances and avoids coating buildup in threaded holes

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in any M3x0.5 threaded application requiring a 90-degree countersunk head profile.

Installation Notes

Installation is performed by machinists or assembly technicians using a 2 mm hex key or hex bit driver. Ensure the mating material is countersunk to 90 degrees at the correct diameter to allow full head seating. Confirm thread fit in the receiving hole before applying final torque to avoid cross-threading in close-tolerance metric applications. Stainless fasteners are susceptible to galling — apply an anti-seize compound appropriate for stainless steel when conditions warrant.
