Metric Blue UST176333 Hex Socket Cap Screw M24x3 150mm

Product Description

The METRIC BLUE UST176333 is a hex socket cap screw designed for high-strength bolted connections in mechanical, industrial, and structural applications. It features an M24 x 3.00 thread profile with a 150 mm length under head, manufactured from alloy steel to material grade 12.9. The grade 12.9 designation indicates an exceptionally high tensile strength, making this fastener appropriate for demanding clamping applications where joint integrity is critical. The Metric Blue coating provides corrosion resistance and a consistent surface finish. Drive type is internal hex, requiring a matching hex key or socket for installation. This part is sold individually.

This screw is suited for heavy equipment assembly, machinery manufacturing, industrial maintenance, and structural bolting applications where high-clamp-load, partially threaded fasteners are specified. The partial threading allows the smooth shank to bear shear loads through the joint, while the threaded section secures the nut or tapped engagement. Trades including millwrights, industrial mechanics, and maintenance technicians commonly use M24 grade 12.9 fasteners in press fits, flanged connections, and equipment frames.

Key Features

• M24 x 3.00 thread size for heavy-duty bolted joints
• 150 mm length under head with partial threading for combined shear and tensile loading
• Grade 12.9 alloy steel construction for very high tensile strength
• Metric Blue coating for corrosion protection and identification
• Internal hex drive per ASME B18.3.1M standard
• Conforms to UNSPSC Code 31161501 for standardized procurement

Compatibility

Designed as a standard metric hex socket cap screw per ASME B18.3.1M, suitable for tapped holes or nuts with M24 x 3.00 thread engagement in industrial and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or industrial technician using a calibrated torque wrench and the correct hex key or socket to meet the specified clamp load for grade 12.9 fasteners. De-energize and lock out all equipment before servicing any bolted assembly. Do not reuse fasteners that have been torqued to yield. Apply thread lubricant only if specified by the equipment manufacturer, as lubrication affects achieved clamp load at a given torque value.
