Metric Blue UST183331 Hex Socket Cap Screw M24x3 65mm

Product Description

The METRIC BLUE UST183331 is a metric hex socket cap screw engineered for high-strength fastening applications. It features an M24 x 3.00 thread size and a length under head of 65 millimeters. Manufactured from alloy steel to material grade 12.9, this screw delivers exceptional tensile strength suitable for heavy-duty mechanical assemblies. The Metric Blue coating provides a proprietary surface treatment for identification and basic corrosion resistance. Installation requires a hex (Allen) key drive matched to the M24 socket head size. This fastener is a standard choice for machinery, structural, and industrial equipment assemblies where high-clamp-load fasteners are specified.

This cap screw is used across a wide range of commercial and industrial applications where grade 12.9 alloy steel fasteners are called out by design specification. Typical install scenarios include heavy equipment assembly, hydraulic cylinder mounting, flange connections, and structural steel fabrication. It is installed by millwrights, maintenance mechanics, pipefitters, and industrial assemblers working to torque specifications defined by the engineering drawing or fastener grade tables. The M24 coarse-thread profile suits applications where thread engagement and load distribution are critical.

Key Features

• M24 x 3.00 metric coarse thread for maximum thread engagement in standard M24 tapped holes
• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• 65 mm length under head accommodates standard stack heights for M24 assemblies
• Hex socket (Allen) drive for high-torque installation in tight clearance environments
• Metric Blue coating for surface protection and grade identification
• UNSPSC Code 31161501 for streamlined procurement classification

Compatibility

Designed as a standard M24 x 3.00 hex socket cap screw suitable for any application specifying a grade 12.9 alloy steel fastener with a 65 mm length under head in a metric coarse-thread configuration.

Installation Notes

Installation should be performed by a qualified mechanic or assembler following the torque values specified on the engineering drawing for grade 12.9 M24 fasteners. De-energize and lock out all associated equipment before servicing any fastened joint. Use a calibrated torque wrench and the correct hex key drive to avoid rounding the socket. Apply thread lubricant or thread-locking compound only when specified by the design authority.
