Holo-krome 87060 Flat Socket Cap Screw M5x0.8 12.9

Product Description

The HOLO-KROME 87060 is a metric flat socket cap screw designed for applications where a flush or countersunk fastening profile is required. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a low-profile head geometry. The 90-degree flat head seats into standard countersunk holes, keeping the fastener surface flush with or below the mating material. A 3.00 mm hex socket drive accepts standard hex keys for precise torque application in confined spaces. The fully threaded shank runs the entire 12.00 mm length, maximizing thread engagement across the full grip range.

This fastener is suited for general mechanical assembly, tooling, fixturing, machine components, and precision equipment where metric hardware conforming to ISO 10642 and ANSI B1.13M standards is specified. The M5x0.8 thread size and 12.9 material grade make it appropriate for high-stress joints in industrial, manufacturing, and maintenance environments. Licensed mechanics and industrial maintenance technicians are the primary installers, though knowledgeable fabricators working to print specifications also use this screw regularly.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load strength
• 90-degree flat head with 11.20 mm head diameter for flush countersunk installations
• 3.00 mm hex socket drive compatible with standard metric hex keys
• Fully threaded 12.00 mm overall length for maximum thread engagement
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Conforms to ISO 10642 and ANSI B1.13M fastener standards with 4G thread fit class

Compatibility

Designed as an OEM-style and general-purpose replacement metric flat socket cap screw for any assembly specifying an M5x0.8 countersunk hex socket fastener to ISO 10642 or ANSI B1.13M.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque requirements for 12.9 grade hardware. Use a properly sized 3.00 mm hex key or driver bit to avoid rounding the socket drive. Verify the mating material contains a correctly sized 90-degree countersink before seating the head fully. Do not mix this high-strength grade screw with low-strength or soft-metal components without confirming joint design requirements.
