Metric Blue UST184124 Flat Socket Cap Screw M10x1.5

Product Description

The METRIC BLUE UST184124 is a metric flat socket cap screw designed for flush or countersunk fastening applications in precision assemblies. It features an M10x1.5 thread and a 90-degree flat head driven by a 6.00 mm hex socket. Built from 12.9 grade alloy steel, this screw delivers high tensile strength suited to heavy-duty clamping and structural fastening tasks. The Metric Blue finish provides a mild corrosion barrier while keeping the hardware identifiable at a glance. At 70.00 mm overall length with full threading, it is well-suited for through-hole and deep-threaded joint applications. Machinists, millwrights, and mechanical contractors are the primary installers.

This flat socket cap screw is used in industrial machinery, hydraulic assemblies, tooling fixtures, and equipment frames where a flush seating surface is required. The 90-degree flat head countersinks cleanly into steel, aluminum, and cast components, keeping joint faces flat without proud hardware. Conforming to DIN 7991 fastener standards, it fits metric-dimensioned designs found in European-spec and ISO-compliant equipment across manufacturing, heavy equipment, and commercial mechanical systems.

Key Features

• 90-degree flat head seats flush in standard countersunk holes, eliminating surface protrusion
• 6.00 mm hex socket drive for high torque application with standard Allen or hex bit tooling
• M10x1.5 thread pitch conforms to standard metric coarse thread specification
• 12.9 grade alloy steel provides maximum tensile and proof load in the metric strength grade series
• Fully threaded 70.00 mm length maximizes thread engagement in through-hole and deep-tap applications
• Metric Blue finish offers surface protection and visual identification on the job

Compatibility

Designed as an OEM-style replacement or new-installation fastener for metric-threaded assemblies requiring a DIN 7991 flat socket cap screw in M10x1.5 with a 12.9 material grade.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a calibrated torque wrench and the correct 6.00 mm hex key or bit. Ensure the mating countersink is machined to the correct 90-degree angle and diameter before driving the fastener. Do not use an impact driver without a torque-limiting setting, as 12.9 grade fasteners are susceptible to brittle failure if over-torqued. Thread the fastener in by hand first to confirm thread engagement and prevent cross-threading.
