Value Collection 532311PR M20x2.5 Socket Cap Screw 220mm

Product Description

The VALUE COLLECTION 532311PR is a metric hex socket cap screw with an M20 x 2.50 thread pitch and a 220 mm length under head. Manufactured from alloy steel to a 12.9 material grade, this fastener delivers high tensile strength suitable for demanding structural and mechanical applications. A black oxide coating provides moderate corrosion resistance and reduces light reflection on exposed surfaces. The partially threaded shank and internal hex drive make it compatible with standard Allen-type hex keys and socket tooling. This fastener conforms to DIN 912 and ISO 898-1 standards. It is sold individually and is appropriate for use by mechanical contractors, millwrights, and industrial maintenance technicians working with metric-standard assemblies.

This screw is used in heavy-duty fastening applications where high clamp load and a flush or low-profile head are required. Typical install scenarios include machinery assembly, structural steel connections, jig and fixture fabrication, and industrial equipment maintenance. The M20 x 2.50 coarse thread is a widely specified pitch in metric mechanical design. The 220 mm length under head suits thick-section or deep-clearance fastening needs. Both the DIN 912 and ISO 898-1 conformances make this fastener suitable for European-standard and globally-sourced equipment.

Compatibility

Designed as a DIN 912 and ISO 898-1 compliant metric socket cap screw suitable for M20 x 2.50 threaded assemblies in industrial, mechanical, and structural applications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with metric fastener torque requirements for 12.9 grade hardware. Verify thread engagement depth and mating thread condition before installation. Use a correctly sized hex key or socket to avoid drive recess damage. Follow applicable equipment manufacturer torque specifications and relevant industry standards when determining final torque values.
