Value Collection A996717 Flat Socket Cap Screw M3x0.5

Product Description

The VALUE COLLECTION A996717 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a compact form factor. The 90-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. The 2.00 mm hex socket drive accepts a standard hex key. Thread size is M3x0.5 and the screw is fully threaded along its 6.00 mm overall length. This package contains 25 pieces and conforms to DIN 7991. Sold in multiples of 1 package.

This screw is suited for precision assemblies in mechanical, industrial, and manufacturing environments where a low-profile fastener is required. The M3x0.5 thread size is commonly used in light machinery, fixtures, enclosures, and electronic or instrumentation hardware. The black oxide finish reduces light reflection and provides mild surface protection, making this fastener a practical choice for interior mechanical assemblies where appearance and clearance both matter. Machinists, millwrights, and mechanical assemblers are the primary installers of this fastener type.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile seats flush in countersunk holes per DIN 7991
• Black oxide finish provides mild corrosion resistance and low-reflectance appearance
• 2.00 mm hex socket drive for precise torque application with standard hex keys
• Fully threaded along the 6.00 mm overall length for maximum thread engagement
• Metric thread standard M3x0.5 for compatibility with metric-dimensioned assemblies

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for use in countersunk applications requiring an M3x0.5 thread. Suitable for any assembly that accepts a standard DIN 7991 compliant flat socket cap screw in the M3 thread class.

Installation Notes

Installation requires a properly countersunk hole at 90 degrees to achieve full flush seating of the flat head. Use a 2.00 mm hex key or driver bit that is in good condition to avoid rounding the socket drive. Apply torque according to the assembly specification for 12.9 grade M3 fasteners. Avoid over-torquing, as M3 fasteners have limited thread engagement volume and can strip or fracture under excessive load.
