Value Collection MKCS20C0809MB M20x2.5 Socket Cap Screw 80mm

Product Description

The VALUE COLLECTION MKCS20C0809MB is a partially threaded socket cap screw designed for high-strength fastening applications in mechanical assemblies, machinery, and structural connections. Manufactured from grade 12.9 alloy steel with a zinc-blue trivalent chromate finish, this fastener delivers superior tensile strength and corrosion resistance. The M20x2.5 coarse-thread profile and 17 mm hex drive allow controlled torque application with a standard hex key or allen driver. At 0.56 pounds per unit, this screw is suited for heavy-duty bolted joint work performed by machinists, millwrights, and maintenance technicians in industrial and commercial environments.

This socket cap screw is appropriate for use in mechanical assemblies requiring a recessed, low-profile head with high clamping force. The partially threaded shank provides a smooth grip zone useful in applications where shear loading is a factor. The 30.00 mm head diameter and 80.00 mm length under head make it a common choice for flanged connections, machine housings, and equipment frames. It complies with DIN 912 and ISO 4762 fastener standards and meets ROHS and REACH requirements, making it suitable for use in regulated manufacturing environments.

Key Features

• Grade 12.9 alloy steel construction for high tensile and yield strength
• Zinc-blue trivalent chromate finish provides corrosion resistance and is ROHS and REACH compliant
• Partially threaded shank supports shear-load applications with a clean grip section
• M20x2.5 coarse right-hand thread for reliable engagement in standard metric tapped holes
• Conforms to DIN 912 and ISO 4762 dimensional standards
• 17 mm internal hex drive for precise torque control with a standard hex key

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for metric M20x2.5 tapped holes in machinery, equipment frames, and structural assemblies conforming to DIN 912 or ISO 4762 specifications.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or maintenance technician using a calibrated torque wrench and a 17 mm hex key or allen bit. Ensure the mating tapped hole is clean and free of debris before installation. De-energize and lock out any machinery before servicing fastened assemblies per applicable safety procedures. Do not exceed the rated clamp load for grade 12.9 hardware as specified by the joint design engineer.
