Holo-krome 87012 Flat Socket Cap Screw M3x0.5 12.9

Product Description

The HOLO-KROME 87012 is a metric flat socket cap screw designed for applications that require a flush or countersunk fastener profile. Manufactured from 12.9 grade alloy steel with a black oxide finish, it provides high tensile strength and moderate corrosion resistance in a low-profile installation. The 90-degree flat head seats flush with or below the surface of the mating material. Drive engagement is through a 2.00 mm hex socket. Thread size is M3x0.5 with an overall length of 12.00 mm. This fastener is installed by machine assemblers, tool and die technicians, and mechanical service professionals who require precision metric hardware.

The 87012 is suited for compact mechanical assemblies, jigs and fixtures, tooling plates, and equipment enclosures where a protruding head would interfere with clearance or moving components. The flush seating of the 90-degree flat head makes it a common choice in tight-tolerance machined parts. The black oxide finish is appropriate for indoor or low-moisture environments. Thread fit class 4G suits standard metric through-hole and tapped applications where controlled fit is required.

Key Features

• 90-degree flat head seats flush or below surface for clearance-critical assemblies
• 12.9 alloy steel grade provides high tensile and proof load strength
• Black oxide finish reduces surface reflectivity and provides light corrosion inhibition
• 2.00 mm hex socket drive for precise torque application in confined spaces
• Conforms to ANSI B1.13M and ISO 10642 fastener standards
• M3x0.5 thread with 4G fit class for consistent metric thread engagement

Compatibility

Designed as an OEM-style metric replacement or service fastener for assemblies requiring a countersunk flat socket cap screw in M3x0.5 thread size per ISO 10642 and ANSI B1.13M standards.

Installation Notes

Installation requires a 2.00 mm hex key or bit driver. Countersink the mating hole to 90 degrees before installation to achieve proper head seating. Power down or de-energize any equipment before fastener replacement in mechanical or electrical assemblies. Do not exceed the rated torque range for 12.9 grade M3 fasteners as specified in the applicable ASME or ISO torque reference for the mating material.
