Value Collection 532527BR M18x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532527BR is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide coating, this screw meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9 — one of the highest strength grades available for metric fasteners. The M18 x 2.50 thread profile with a 90 mm length under head makes it suited for heavy-duty bolted connections where reliable clamping force and corrosion resistance are required. It is installed using a hex socket drive, which allows high torque application in confined spaces.

This cap screw is used in a wide range of applications including machine tool assemblies, industrial equipment mounting, die and mold construction, and structural steel fabrication. The partially threaded shank provides a smooth grip zone that resists shear loads, making it appropriate for precision-fitted holes in heavy equipment and manufacturing environments. Maintenance technicians, machinists, and millwrights commonly specify grade 12.9 alloy steel fasteners for high-load and vibration-prone assemblies.

Key Features

• Grade 12.9 alloy steel construction for maximum tensile and proof load strength
• Black oxide coating provides mild corrosion resistance and reduces light reflection on exposed surfaces
• Partially threaded shank improves shear resistance in precision-fit applications
• Hex socket drive allows high-torque installation in restricted clearance areas
• Meets DIN 912 and ISO 898-1 fastener standards for dimensional and mechanical conformance

Compatibility

Designed as a standard metric hex socket cap screw for use in any application requiring an M18 x 2.50 thread pitch, 90 mm length under head, DIN 912-compliant fastener.

Installation Notes

Installation should be performed by qualified machinists, millwrights, or maintenance technicians using a calibrated torque wrench and the appropriate hex socket key. Consult applicable engineering standards or equipment manufacturer specifications for required torque values, as grade 12.9 fasteners are sensitive to over- and under-torquing. Ensure mating threads are clean and free of debris before assembly. De-energize and lock out all equipment before disassembly or replacement of structural fasteners.
