Value Collection 532320BR M20x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532320BR is a metric hex socket cap screw designed for high-strength fastening applications. It features an M20 x 2.50 thread size with a 160 mm length under the head and is partially threaded. Constructed from alloy steel with a black oxide coating, this fastener meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating high tensile strength suitable for demanding mechanical and structural assemblies. Machinists, maintenance technicians, and industrial mechanics rely on this type of fastener where a recessed hex drive and flush or low-profile head are required.

This screw is suited for use in industrial machinery, heavy equipment, tooling fixtures, and structural assemblies where high clamp load and precision thread engagement are required. The M20 coarse pitch thread and 160 mm under-head length make it appropriate for thick-section joints in steel fabrication, press frames, mold bases, and similar applications. The black oxide finish offers mild corrosion resistance in controlled indoor environments.

Key Features

• M20 x 2.50 metric thread with 160 mm length under head
• Partially threaded shank for improved shear strength in bolted joints
• Grade 12.9 alloy steel for high tensile and proof load capacity
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• Hex socket drive for torque application in confined or recessed spaces
• Compliant with DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw, this fastener is compatible with M20 x 2.50 threaded holes in steel, cast iron, and other metallic assemblies per ISO 898-1 specifications.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians using a calibrated torque wrench and the appropriate size hex key or Allen driver. De-energize, depressurize, or lock out all associated equipment before fastener removal or installation per applicable OSHA lockout/tagout procedures. Grade 12.9 fasteners should not be substituted with lower-grade hardware, and reuse of previously torqued high-strength fasteners should be evaluated per the equipment manufacturer's guidelines.
