Holo-krome 87032 Flat Socket Cap Screw M4x0.7 Alloy Steel

Product Description

The HOLO-KROME 87032 is a metric flat socket cap screw designed for flush or countersunk fastening applications in precision assemblies. It features a 90-degree flat head with a 2.55 mm hex socket drive and is manufactured from 12.9 grade alloy steel with a black oxide finish. The M4x0.7 thread and 12.00 mm overall length make it suited for tight-tolerance mechanical assemblies where head protrusion must be minimized. The 12.9 material grade indicates high tensile strength, making this screw appropriate for high-stress, load-bearing connections. Installation is typically performed by mechanical technicians and precision assembly professionals using a 2.55 mm hex key.

This flat socket cap screw is used in applications where a countersunk, low-profile fastener is required. The 90-degree flat head seats flush with or below the surface of the mating component, eliminating protrusion that could interfere with adjacent parts or mating surfaces. Typical applications include machine assemblies, tooling fixtures, robotics, and other precision mechanical equipment. The black oxide finish provides mild corrosion resistance and reduces light reflection in sensitive environments. This screw conforms to ANSI B1.13M and ISO 10642 fastener standards.

Key Features

• 90-degree flat head seats flush in countersunk holes to eliminate surface protrusion
• 12.9 grade alloy steel construction provides high tensile strength for load-bearing joints
• 2.55 mm hex socket drive for precise torque application with standard hex keys
• Black oxide finish offers mild corrosion resistance and low-reflectance appearance
• Conforms to ANSI B1.13M and ISO 10642 fastener standards
• Thread fit class 4G for consistent metric thread engagement

Compatibility

Designed for use in countersunk holes conforming to M4x0.7 metric thread specifications per ANSI B1.13M and ISO 10642 standards. Compatible with any M4x0.7 threaded application requiring a 90-degree flat head profile.

Installation Notes

Installation should be performed by a qualified mechanical technician or assembly professional. Ensure the mating countersunk hole is machined to the correct 90-degree angle and depth before installation. Use a calibrated 2.55 mm hex key to drive the screw and avoid cam-out that could damage the socket. Do not exceed the torque rating appropriate for 12.9 grade M4 fasteners as specified by the equipment manufacturer or applicable industry standards.
