Value Collection 532313PR M20 X 2.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532313PR is a metric hex socket cap screw rated for high-strength fastening applications. Built from alloy steel with a black oxide coating, this fastener meets DIN 912 and ISO 898-1 standards at a material grade of 12.9 — one of the highest tensile strength grades available for metric cap screws. The M20 x 2.50 thread profile and 240 mm length under head make it well suited for heavy-duty assemblies where a flush, recessed-head profile is required. Installation requires an appropriately sized hex key or Allen driver. This screw is used by millwrights, maintenance mechanics, and industrial tradespeople working on machine assemblies, structural fixtures, and equipment mounting applications.

This fastener fits applications calling for a partially threaded M20 x 2.50 metric hex socket cap screw with a 240 mm length under head. The DIN 912 standard governs the head dimensions and thread form, making this a recognized replacement or build-spec option for European and metric-standard machinery. The black oxide finish provides mild corrosion resistance and reduces light glare in precision assemblies. Typical use cases include hydraulic press frames, conveyor systems, industrial machine bases, and heavy equipment jigs.

Key Features

• Grade 12.9 alloy steel construction — high tensile and proof load strength for critical fastening joints
• M20 x 2.50 metric thread, partially threaded shank for controlled clamping in thick-material assemblies
• 240 mm length under head accommodates deep or stacked material joints
• Black oxide coating provides mild corrosion resistance and a uniform dark finish
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Hex socket drive accepts standard hex keys and power-tool hex bits

Compatibility

Designed as a direct-spec metric hex socket cap screw for applications requiring an M20 x 2.50 thread, 240 mm under-head length, partially threaded shank, and DIN 912 head geometry.

Installation Notes

Installation of Grade 12.9 hex socket cap screws should be performed by qualified mechanics or millwrights familiar with metric fastener torque requirements for the specific joint material and application. Always de-energize and lock out equipment before fastener installation or removal per OSHA lockout-tagout procedures. Use a calibrated torque wrench and the correct hex key size to avoid cam-out or fastener damage. Do not substitute lower-grade fasteners in joints specified for Grade 12.9 hardware.
