Value Collection 644227PR Hex Head Cap Screw M12x1.25 70mm

Product Description

The VALUE COLLECTION 644227PR is a metric hex head cap screw designed for precision fastening applications requiring a fine-thread pitch. Built to Grade 8.8 steel specifications, it delivers reliable tensile strength for medium-to-high load assemblies. The partially threaded shank provides a smooth bearing surface along part of the grip length, which is important when clamping two components together without thread engagement in the joint area. At M12 x 1.25 with a 70 mm length under head and a 19 mm hex drive, this fastener meets DIN 960 and ISO 8765 dimensional standards. Installers working on mechanical assemblies, machinery, or structural metalwork will find this screw suited to applications where metric fine-thread fasteners are specified.

This cap screw is used in applications calling for a metric fine-pitch M12 fastener, such as machinery frames, automotive components, hydraulic equipment, and precision mechanical assemblies. The fine 1.25 mm thread pitch offers greater resistance to loosening under vibration compared to coarse-thread equivalents of the same diameter. The bright, uncoated finish is suitable for use in dry or controlled environments where corrosion resistance is not a primary requirement. Minimum order quantity is 5 pieces.

Key Features

• M12 x 1.25 fine-thread pitch meets DIN 960 and ISO 8765 standards
• Grade 8.8 steel construction provides proven medium-high tensile strength for structural and mechanical use
• Partially threaded shank allows full clamping load between mating surfaces without threading through the joint
• 19 mm hex head drive accommodates standard metric wrenches and sockets
• 70 mm length under head suits applications requiring extended grip length
• Bright, uncoated finish for use in clean, dry operating environments

Compatibility

Designed as an OEM-style replacement or service fastener for metric fine-thread applications requiring an M12 x 1.25 hex head cap screw conforming to DIN 960 or ISO 8765 dimensional specifications.

Installation Notes

Installation is typically performed by mechanical assemblers, millwrights, or maintenance technicians using a standard 19 mm metric wrench or socket. Always verify that the mating threaded hole or nut is rated to an equivalent or higher grade before installation. Fasteners should be installed to the torque value specified by the equipment manufacturer for Grade 8.8 M12 fasteners. Do not mix metric fine-thread fasteners with coarse-thread hardware of the same nominal diameter.
