Value Collection 644250PS M20 Hex Cap Screw Grade 8.8 Steel

Product Description

The VALUE COLLECTION 644250PS is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It features an M20 x 2.50 thread profile with a 120 mm length under the head and is partially threaded, conforming to DIN 931 and ISO 4014 standards. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this screw delivers reliable tensile strength for structural and mechanical assemblies. The 30 mm hex drive size accommodates standard metric wrenches and sockets used in industrial maintenance, equipment assembly, and fabrication environments.

This cap screw is suited for medium-to-heavy duty bolted connections in machinery, structural steel work, and equipment fabrication. The partial threading is characteristic of DIN 931 and ISO 4014 specifications, making it appropriate for applications where a grip length is needed or where the unthreaded shank must pass through a clearance hole before engaging the nut or tapped bore. Maintenance technicians, millwrights, and fabricators commonly use this size in industrial settings.

Key Features

• M20 x 2.50 metric thread profile with 120 mm length under head
• Grade 8.8 steel construction for consistent tensile and yield strength
• Partially threaded shank per DIN 931 and ISO 4014 standards
• Bright, uncoated finish suitable for use with additional coatings or as-installed
• 30 mm hex drive compatible with standard metric wrenches and impact sockets

Compatibility

Designed as a standard DIN 931 and ISO 4014 metric hex head cap screw, suitable for use with M20 x 2.50 metric nuts, threaded inserts, and tapped holes conforming to metric thread standards.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or fabricators using standard metric wrenches or impact tools sized for a 30 mm hex. Always verify that mating threads, nuts, or tapped bores conform to M20 x 2.50 metric specifications before installation. Follow applicable torque guidelines for Grade 8.8 fasteners as specified by the equipment manufacturer or relevant industry standards. Inspect threads for damage and ensure mating surfaces are clean and free of debris before assembly.
