Value Collection 644235PS Hex Head Cap Screw M20 X 2.50 X 70mm

Product Description

The VALUE COLLECTION 644235PS is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It features an M20 x 2.50 thread with a nominal length under head of 70 mm and is partially threaded, conforming to DIN 931 and ISO 4014 standards. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener delivers reliable clamping force in structural and machine assembly work. It is a standard metric fastener installed by maintenance technicians, millwrights, and industrial mechanics across a wide range of equipment and fabrication applications.

This screw is suited for medium-to-high-strength bolted joints in industrial machinery, structural steel assemblies, and equipment frames where metric fasteners are specified. The partial threading leaves a smooth shank section that resists shear loads at the joint interface, making it appropriate for through-bolt and flanged connection configurations. Grade 8.8 steel provides a tensile strength suitable for demanding mechanical assemblies in both production and field maintenance environments.

Key Features

• M20 x 2.50 metric thread for use in standard metric tapped holes and with metric nuts
• 70 mm length under head, partially threaded per DIN 931 and ISO 4014
• Grade 8.8 steel construction for medium-to-high tensile strength fastening
• Bright, uncoated finish suitable for dry or lightly lubricated indoor applications
• 30 mm hex key drive size for use with standard metric wrenches and sockets
• UNSPSC Code 31161501 for procurement and inventory classification

Compatibility

Designed as a standard metric hex head cap screw compatible with M20 x 2.50 metric tapped holes and M20 metric hex nuts in industrial machinery, structural assemblies, and equipment requiring DIN 931 or ISO 4014 compliant fasteners.

Installation Notes

Installation is performed by maintenance technicians or millwrights using a metric wrench or socket sized to the 30 mm hex. Always verify thread engagement depth meets engineering requirements before final torque. Follow applicable machine or structural specifications for required torque values, as no torque spec is provided with this fastener alone. Ensure mating threads are clean and free of debris before installation to avoid galling or false torque readings.
