Holo-krome 87205 Flat Socket Cap Screw M12x1.75 12.9

Product Description

The HOLO-KROME 87205 is a metric flat socket cap screw designed for applications where a low-profile, flush-mount fastener is required. Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in demanding assemblies. The 90-degree flat head seats flush with or below the mating surface, and the 8 mm hex socket drive accepts standard hex keys for reliable torque transmission. With an M12x1.75 thread and an overall length of 55 mm, it is fully threaded from tip to head. Machinists, millwrights, and industrial maintenance technicians working with metric hardware are the primary installers.

This screw is suited for use in mechanical assemblies, fixtures, machine frames, and equipment where a countersunk fastener is needed to eliminate protrusions. The fully threaded design provides consistent clamping force along the full grip length. The black oxide finish reduces galling and light surface oxidation in indoor or low-moisture environments. Applications span general industrial manufacturing, tooling plates, and precision equipment that requires metric fasteners conforming to ANSI B1.13M and ISO 10642 standards.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load strength
• 90-degree flat head with 8 mm hex socket drive for flush-mount installation
• Black oxide finish for reduced galling and light corrosion resistance
• Fully threaded M12x1.75 metric thread along entire 55 mm length
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed as an OEM-style metric replacement or new-installation flat socket cap screw for mechanical assemblies requiring ISO 10642 and ANSI B1.13M compliant M12x1.75 countersunk socket fasteners.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and a properly sized 8 mm hex key or hex bit socket. Ensure the mating countersink is machined to a 90-degree included angle to achieve full head seating. De-energize, depressurize, or lock out the assembly per applicable OSHA lockout/tagout procedures before fastener replacement. Do not exceed the rated torque for 12.9 grade M12 hardware as published in the applicable fastener standard.
