Holo-krome 87076 Flat Socket Cap Screw M5x0.8 12.9 Alloy Steel

Product Description

The HOLO-KROME 87076 is a metric flat socket cap screw engineered for applications requiring a flush or countersunk fastener profile. Sized at M5x0.8 with a 30 mm overall length, it is fully threaded and features a 90-degree flat head driven by a 3.00 mm hex socket. Manufactured from 12.9 grade alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance. The 12.9 material grade indicates an exceptionally strong fastener suited for high-stress mechanical assemblies. Licensed machinists, millwrights, and maintenance technicians working in precision fabrication, tooling, and industrial equipment commonly install this style of fastener.

This flat socket cap screw is used in applications where a low-profile or flush-mount fastener is required and a standard hex cap head would protrude unacceptably. Typical installation scenarios include machine frames, jigs, fixtures, brackets, and enclosures in industrial and manufacturing environments. The black oxide finish provides a clean appearance and mild surface protection against incidental moisture exposure. The M5x0.8 thread size is a standard metric pitch widely encountered in metric-dimensioned equipment and machinery.

Key Features

• 90-degree flat head profile for flush or countersunk installations
• 12.9 alloy steel grade provides high tensile and proof load strength
• Black oxide finish for surface protection and reduced light reflection
• 3.00 mm hex socket drive for standard hex key or Allen wrench installation
• Fully threaded along the entire 30 mm length for maximum engagement in thin materials
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed as an OEM-style and aftermarket replacement flat socket cap screw for metric-threaded M5x0.8 applications in industrial machinery, fixtures, and precision fabrication assemblies.

Installation Notes

Installation should be performed by qualified maintenance technicians or machinists using a calibrated 3.00 mm hex key or Allen driver. Ensure the mating hole is correctly countersunk to 90 degrees to achieve proper head seating and load distribution. De-energize and lock out all power sources on equipment before fastener removal or replacement per applicable OSHA lockout/tagout procedures. Do not exceed the rated capacity of the fastener by overtorquing; consult applicable engineering references for torque values appropriate to 12.9 grade M5 fasteners in the specific joint material.
