Holo-krome 87072 Flat Socket Cap Screw M5x0.8 25mm

Product Description

The HOLO-KROME 87072 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built from grade 12.9 alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance in a compact, low-profile head. The 90-degree flat head seats into standard metric countersinks and is driven by a 3 mm hex socket. The M5x0.8 thread is fully threaded along the 25 mm overall length, conforming to ANSI B1.13M and ISO 10642 standards. Maintenance technicians, machinists, and OEM assembly crews working with metric fastener systems are the primary installers of this screw.

This screw is suited for use in metal fabrication, machine assembly, and equipment maintenance wherever a low-profile countersunk fastener is required. The 12.9 grade rating indicates a minimum tensile strength appropriate for high-stress structural and mechanical joint applications. The black oxide finish reduces surface reflectivity and provides light lubricity during installation. Sold individually with a minimum order quantity of 100 pieces per order, making it appropriate for production or bulk service inventory.

• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed as an OEM-style and maintenance replacement metric flat socket cap screw for equipment, fixtures, and assemblies using M5x0.8 countersunk socket fasteners conforming to ISO 10642.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians. Power down and de-energize all equipment before accessing fastener locations on live machinery. Use a calibrated torque wrench with a 3 mm hex bit and follow the torque specifications provided by the equipment manufacturer for grade 12.9 M5 fasteners. Inspect the countersink bore for damage or contamination before seating the screw to ensure full head contact and proper clamp load.
