Holo-krome 87149 Flat Socket Cap Screw M10x1.5

Product Description

The HOLO-KROME 87149 is a metric flat socket cap screw designed for flush or countersunk fastening in precision assemblies. It features an M10x1.5 thread, a 90-degree flat head with a 6.00 mm hex socket drive, and is fully threaded along its 16.00 mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance. The head diameter measures 22.40 mm. This fastener meets ANSI B1.13M and ISO 10642 standards and carries a Thread Fit Class 4G designation. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in applications where a standard cap screw head would interfere with mating surfaces.

The 87149 is suited for industrial machinery, precision equipment, and structural assemblies that require a countersunk socket fastener profile. The 90-degree flat head seats flush into chamfered holes, making it appropriate for tight-clearance designs in manufacturing fixtures, tooling plates, and mechanical assemblies. The black oxide finish reduces light reflection and provides a degree of surface protection in dry or lightly oiled environments. This screw is sold individually but is subject to a minimum order quantity of 100 pieces.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile seats flush in countersunk holes
• 6.00 mm hex socket drive accepts standard hex keys and socket bits
• Fully threaded along entire 16.00 mm length for maximum thread engagement
• Black oxide finish for reduced reflectivity and light surface protection
• Meets ANSI B1.13M and ISO 10642 fastener standards with Thread Fit Class 4G

Compatibility

Designed as an OEM-style metric flat socket cap screw compatible with countersunk M10x1.5 tapped hole applications conforming to ISO 10642 and ANSI B1.13M standards.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or socket driver. Verify that the mating countersink angle matches the 90-degree flat head geometry before installation. De-energize or lock out any equipment per applicable safety procedures before fastening. Do not substitute a lower-grade fastener in applications engineered for 12.9 class hardware.
