Holo-krome 87200 Flat Socket Cap Screw M12x1.75 45mm

Product Description

The HOLO-KROME 87200 is a metric flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength in a compact, low-profile head format. The 90-degree flat head seats flush in countersunk holes, and the 8.00 mm hex socket drive allows precise torque application with standard hex keys. The fully threaded M12x1.75 shank at 45 mm overall length suits close-tolerance assemblies in industrial, mechanical, and structural installations. Licensed tradespeople and machine technicians are the primary installers.

This fastener is suited for metric mechanical assemblies, tooling fixtures, machine frames, and industrial equipment requiring a flush-mounted high-strength screw. The M12x1.75 thread pitch conforms to ANSI B1.13M and ISO 10642 standards, making it compatible with metric countersunk hole patterns in steel, aluminum, and similar materials. The black oxide finish provides moderate corrosion resistance and reduces light reflection, which is useful in precision and optical tooling environments. Sold individually, with a minimum order quantity of 5 pieces.

Key Features

• 8.00 mm hex socket drive for controlled torque input
• Fully threaded M12x1.75 shank, 45 mm overall length
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed for use in metric countersunk applications conforming to ISO 10642 and ANSI B1.13M standards, with a 4G thread fit class for standard metric clearance holes.

Installation Notes

Installation requires an 8.00 mm hex key or socket driver rated for high-torque applications. De-energize and lock out any equipment before fastener replacement or installation in live machinery. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for 12.9 grade M12 fasteners. Inspect countersunk hole geometry for proper 90-degree angle and diameter before seating to avoid head deformation.
