Holo-krome 87132 Flat Socket Cap Screw M8x1.25

Product Description

The HOLO-KROME 87132 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head with a 5 mm hex socket drive and is manufactured from 12.9 grade alloy steel with a black oxide finish. The M8x1.25 thread is fully threaded along its 25 mm overall length. This grade 12.9 fastener delivers high tensile strength suitable for demanding mechanical assemblies. It is installed by machinists, maintenance technicians, and mechanical contractors working on precision equipment, tooling fixtures, and structural assemblies.

This flat socket cap screw is suited for metric fastening applications in manufacturing, industrial machinery, and equipment assembly where a low-profile head is required to sit flush with or below the mating surface. The 90-degree countersunk head conforms to ANSI B1.13M and ISO 10642 fastener standards, making it appropriate for both domestic and international equipment specifications. Thread fit class 4G ensures reliable engagement in metric tapped holes. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 90-degree flat countersunk head provides a flush-mount profile in countersunk holes
• 5 mm hex socket drive for use with standard hex keys or socket drivers
• 12.9 grade alloy steel construction delivers high tensile and proof load capacity
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Fully threaded along the 25 mm overall length for maximum thread engagement
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed for use in metric tapped holes with M8x1.25 thread specification and thread fit class 4G. Suitable for countersunk fastening applications conforming to ISO 10642 and ANSI B1.13M standards.

Installation Notes

Installation is performed by machinists or maintenance technicians using a calibrated hex key or torque wrench fitted with a 5 mm hex bit. Ensure the mating surface is properly countersunk to 90 degrees before installation. Do not exceed the torque rating specified for 12.9 grade M8 fasteners per the applicable engineering standard for the assembly. Inspect threads for damage before installation and replace any fastener that shows signs of galling or deformation.
