Holo-krome 87008 Flat Socket Cap Screw M3x0.5

Product Description

The HOLO-KROME 87008 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Threaded M3x0.5 and manufactured from grade 12.9 alloy steel with a black oxide finish, this screw delivers high tensile strength in a compact form factor. The 90-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. Drive engagement is through a 2.00 mm hex socket. This fastener is installed by machinists, millwrights, and precision assembly technicians in tooling, fixtures, machinery, and mechanical assemblies.

The 87008 is suited for metric fastening applications in manufacturing, industrial equipment, and precision mechanical assemblies where a low-profile countersunk fastener is required. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or instrumentation environments. Overall length is 10.00 mm. This screw conforms to ANSI B1.13M and ISO 10642 fastener standards, making it appropriate for controlled-fit metric assemblies requiring thread fit class 4G.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile for flush countersunk installation
• 2.00 mm hex socket drive for precise torque application
• Black oxide finish for mild corrosion resistance and low reflectivity
• Conforms to ANSI B1.13M and ISO 10642 fastener standards
• Thread fit class 4G for controlled metric thread engagement

Compatibility

Designed for metric M3x0.5 countersunk socket cap screw applications conforming to ISO 10642 and ANSI B1.13M standards.

Installation Notes

Installation requires a 2.00 mm hex key or driver. The mating hole must be properly countersunk to a 90-degree included angle to achieve full flush seating. De-energize or lock out any equipment before fastener replacement or removal in live machinery. Do not substitute imperial hex keys, as rounding the socket drive will damage the fastener.
