Value Collection MKCS20C0509MB M20x2.5 Socket Cap Screw

Product Description

The VALUE COLLECTION MKCS20C0509MB is an M20x2.5 socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. Manufactured from alloy steel at a 12.9 material grade, this screw delivers exceptional tensile and proof-load strength suitable for demanding structural connections. The head accepts a 17 mm hex drive key for installation and removal. A zinc-blue trivalent chromate finish provides corrosion resistance while maintaining RoHS and REACH compliance. The fully threaded shank with coarse right-hand threading ensures reliable engagement across the full bearing length. This fastener conforms to DIN 912 and ISO 4762 standards.

This socket cap screw is suited for use in machinery assembly, fixture fabrication, equipment maintenance, and structural bolted connections where high clamp load is required. The M20 diameter and 50 mm length under head make it appropriate for medium-to-heavy fastening tasks encountered by millwrights, maintenance technicians, and mechanical contractors working on industrial or commercial equipment. It is sold individually and can be ordered in the required quantity for the job at hand.

Key Features

• M20x2.5 coarse right-hand thread for standard metric fastening
• 12.9 alloy steel material grade provides high tensile strength
• Fully threaded shank maximizes thread engagement over the 50 mm length
• 17 mm internal hex drive for use with standard hex keys or Allen drivers
• Zinc-blue trivalent chromate finish for corrosion protection and RoHS/REACH compliance
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric socket cap screw, compatible with any application requiring an M20x2.5 coarse-thread fastener with a 50 mm length under head.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with metric fastener torque requirements for 12.9-grade hardware. Use a properly sized 17 mm hex key or driver to avoid rounding the drive recess. Ensure mating threads are clean and free of debris before installation. Do not reuse fasteners that show signs of thread damage or deformation.
