Holo-krome 87114 Flat Socket Cap Screw M6x1 50mm 12.9

Product Description

The HOLO-KROME 87114 is a metric flat socket cap screw engineered for applications requiring a low-profile, flush-mount fastener with high tensile strength. Built from grade 12.9 alloy steel with a black oxide finish, it delivers the clamping force needed in tight assemblies where a standard cap screw head would interfere with mating surfaces. The 90-degree flat head seats flush when installed into a properly countersunk bore. Drive engagement is through a 4.00 mm hex socket, and the fastener is partially threaded along its 50 mm overall length. Licensed HVAC, mechanical, and industrial technicians routinely spec this fastener in equipment panels and precision assemblies.

This screw is suited for metric fastening applications in machinery, fixtures, and equipment enclosures where a countersunk, flush-mount profile is required. The M6x1 thread size is common in light industrial and OEM equipment. Thread fit class is 4G per ANSI B1.13M and ISO 10642, making it compatible with standard metric tapped holes in that tolerance range. The black oxide finish provides mild corrosion resistance and reduces light reflection, which is useful in tooling and precision instrument builds. Minimum order quantity is 10 pieces.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile allows flush countersunk installation
• 4.00 mm hex socket drive for precise torque application
• M6x1 metric thread with 4G fit class per ANSI B1.13M and ISO 10642
• Black oxide finish for mild corrosion resistance and low reflectivity
• Partially threaded shank over 50 mm overall length

Compatibility

Designed for use in standard metric countersunk holes requiring an M6x1 thread. Conforms to ANSI B1.13M and ISO 10642 fastener standards, ensuring fitment with metric tapped components machined to those specifications.

Installation Notes

Installation should be performed with a calibrated hex key or hex bit driver sized to 4.00 mm. The receiving bore must be countersunk to 90 degrees to achieve proper head seating and flush fit. De-energize and lock out any equipment before fastener service where applicable. Follow equipment manufacturer torque specifications for grade 12.9 hardware when reassembling critical joints.
