Value Collection 644033PR Hex Head Cap Screw M10x1 40mm

Product Description

The VALUE COLLECTION 644033PR is a metric hex head cap screw designed for mechanical assemblies requiring a fine-thread, partially threaded fastener. It carries an M10 x 1.00 mm thread profile with a 40 mm length under the head and is manufactured from Grade 8.8 steel with a bright, uncoated finish. The 17 mm hex drive is compatible with standard wrenches and sockets. This fastener conforms to DIN 960 and ISO 8765 dimensional standards, making it a reliable choice for precision bolting applications where thread engagement length and pitch matter. Machinists, maintenance mechanics, and field technicians install this screw in equipment, machinery, and structural assemblies across industrial and commercial environments.

This screw is suited for metric bolting applications in industrial machinery, manufacturing equipment, and mechanical assemblies where fine-thread engagement is required. The partially threaded shank provides a grip area that resists loosening under vibration and cyclic loading. It is commonly installed by millwrights, maintenance technicians, and general mechanics working on equipment with metric fastener specifications. The Grade 8.8 material designation indicates a medium-high tensile strength appropriate for general mechanical fastening where higher-grade alloy fasteners are not specified.

Key Features

• M10 x 1.00 mm fine-thread pitch conforming to metric thread standards
• 40 mm length under head for precise grip-length control
• Partially threaded shank improves clamping force and vibration resistance
• Grade 8.8 steel construction provides medium-high tensile strength
• Bright uncoated finish suitable for applications where coating compatibility is a concern
• Meets DIN 960 and ISO 8765 dimensional standards

Compatibility

Designed as an OEM-style metric replacement fastener for machinery, equipment, and mechanical assemblies specifying an M10 x 1.00 partially threaded hex head cap screw per DIN 960 or ISO 8765.

Installation Notes

Installation requires a 17 mm wrench or socket. Power down and de-energize any equipment before fastener replacement or service. Follow the equipment manufacturer's torque specifications for M10 Grade 8.8 fasteners as found in the applicable service documentation. Inspect threads on both the fastener and the receiving bore for damage or contamination before installation.
