Value Collection 532321BR M20x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532321BR is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel to material grade 12.9, this fastener delivers exceptional tensile and proof load strength suitable for demanding load-bearing connections. The black oxide finish provides a base level of corrosion resistance and reduces light reflection in service environments. With an M20 x 2.50 thread profile and a 180 mm length under head, it is installed using a hex socket drive. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This cap screw is suited for use in heavy equipment assembly, machine tool construction, hydraulic manifold mounting, and other applications requiring a high-clamp-load metric fastener. The partially threaded shank allows for precise shear loading in close-tolerance bores. It conforms to DIN 912 and ISO 898-1 standards, making it appropriate for applications where fastener grade and dimensional compliance are specified by engineering drawings or OEM maintenance procedures.

Key Features

• Alloy steel construction rated to material grade 12.9 for high tensile strength
• Black oxide coating provides mild corrosion resistance and a clean appearance
• M20 x 2.50 thread size with partially threaded shank for shear-load applications
• 180 mm length under head accommodates deep joint stacks
• Hex socket drive for high torque input in confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for any assembly or maintenance application specifying an M20 x 2.50 grade 12.9 alloy steel socket cap screw.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician using a calibrated torque wrench and the correct hex socket bit for M20 fasteners. De-energize and lock out all equipment before fastener service per applicable OSHA lockout/tagout procedures. Grade 12.9 fasteners are sensitive to hydrogen embrittlement; avoid impact installation methods and follow engineering-specified torque values for the joint design. Thread engagement depth and lubrication conditions will affect final clamp load and should be accounted for per the applicable design standard.
