Value Collection 644036PR M10x1 Hex Cap Screw 45mm Grade 8.8

Product Description

The VALUE COLLECTION 644036PR is a metric hex head cap screw designed for mechanical fastening applications requiring close thread tolerances and controlled clamping force. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener has a thread size of M10 x 1.00, a length under head of 45 mm, and a 17 mm hex drive. The partial threading leaves a smooth shank section between the head and the threaded portion, which is important in joints that need the fastener to act as a shoulder or to avoid cross-threading in close-tolerance assemblies. It conforms to DIN 960 and ISO 8765 standards.

This screw is suited for general industrial, mechanical, and structural assembly work where metric fine-thread fasteners are specified. Fine-pitch M10 threads provide higher thread engagement and improved resistance to loosening under vibration compared to coarse-pitch equivalents. Typical applications include machine frames, equipment enclosures, automotive components, and fabricated assemblies where Grade 8.8 carbon steel tensile strength is required. This fastener is sold in minimum order quantities of 10 units.

Key Features

• M10 x 1.00 fine metric thread for high vibration resistance and precise clamping
• 45 mm length under head with partial threading for shoulder-bearing joints
• Grade 8.8 steel construction for high tensile and yield strength in structural applications
• Bright uncoated finish — suitable for use as-is or for further plating or coating by the installer
• 17 mm hex drive compatible with standard metric wrenches and sockets
• Conforms to DIN 960 and ISO 8765 dimensional and material standards

Compatibility

Designed as a standard DIN 960 and ISO 8765 metric fine-thread hex head cap screw for use in any assembly specifying an M10 x 1.00 partially threaded fastener in Grade 8.8 steel.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or mechanical assemblers using a standard 17 mm open-end, box, or socket wrench. Torque to the value specified in the applicable engineering drawing or fastener torque table for Grade 8.8 M10 fine-thread fasteners — do not estimate torque without a reference. Ensure mating threads are clean and free of debris before installation. Thread-locking compounds are optional and should be selected based on joint requirements and disassembly needs.
