Value Collection 644275PS M12x1.25x80mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644275PS is a metric hex head cap screw designed for bolted assemblies requiring a fine-pitch thread and partial threading along the shank. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets DIN 960 and ISO 8765 standards. It features an M12 x 1.25 thread size — a fine pitch variant of the standard M12 — with an 80 mm length under head and a 19 mm hex drive. The partial threading allows the unthreaded shank to bear shear loads, making it suitable for applications where precise alignment and clamping are critical. Installed by millwrights, maintenance mechanics, and machine builders working to metric specifications.

This screw is suited for industrial machinery, equipment assemblies, and structural connections where a metric fine-thread fastener is specified. The fine 1.25 mm pitch provides greater resistance to loosening under vibration compared to coarse-thread equivalents, making it a common choice in automotive, hydraulic, and precision mechanical assemblies. The uncoated finish is appropriate for dry indoor environments or applications where a secondary coating or locking compound will be applied by the installer.

Key Features

• M12 x 1.25 fine-pitch metric thread per DIN 960 and ISO 8765
• Grade 8.8 steel construction for high tensile strength fastener applications
• Partially threaded shank for shear load bearing and precise joint alignment
• 19 mm hex drive compatible with standard metric wrenches and sockets
• Bright, uncoated finish — suitable for secondary coating or indoor dry use
• 80 mm length under head for medium-depth bolted connections

Compatibility

Designed as a standard metric fine-thread hex head cap screw conforming to DIN 960 and ISO 8765, suitable for use in any bolted assembly specifying an M12 x 1.25 partially threaded fastener in Grade 8.8 steel.

Installation Notes

Installation is performed by qualified mechanical technicians or millwrights using a metric wrench or socket sized to 19 mm. Fastener torque should be determined from the applicable engineering specification or torque table for Grade 8.8 M12 fine-thread fasteners — do not substitute a value from a different grade or thread pitch. Ensure mating threads are clean and free of debris before assembly. If a locking compound or anti-seize is required, apply per the assembly drawing or equipment service manual.
