Value Collection 643166PR Hex Head Cap Screw M16 X 2.00 Grade 8.8

Product Description

The VALUE COLLECTION 643166PR is a metric hex head cap screw designed for general-purpose fastening in mechanical assemblies, structural connections, and equipment fabrication. The fastener is manufactured from Grade 8.8 steel in an uncoated bright finish, conforming to DIN 933 and ISO 4017 standards. The M16 x 2.00 thread profile spans the full length under the head at 70 mm, with a 24 mm hex drive. These screws are installed by millwrights, maintenance technicians, fabricators, and industrial mechanics working in metric-standard applications.

This screw is suited for metal-to-metal fastening in industrial machinery, structural steel assemblies, and equipment frames where a metric M16 coarse-thread fastener is specified. The fully threaded shank allows engagement along the entire 70 mm length under the head, making it appropriate for through-bolt configurations or applications requiring maximum thread contact. Grade 8.8 steel provides a reliable strength class for general structural and mechanical use without the need for higher-alloy fasteners.

Key Features

• M16 x 2.00 metric coarse thread, fully threaded along the 70 mm length under head
• Grade 8.8 steel construction meets DIN 933 and ISO 4017 dimensional and mechanical standards
• 24 mm hex drive for standard open-end, box, or socket wrench installation
• Bright uncoated finish suitable for dry or internally lubricated fastening applications
• Weighs 0.287 pounds per piece, consistent with standard M16 hex cap screw mass

Compatibility

Designed as a standard metric replacement or stock fastener for any assembly specifying an M16 x 2.00 x 70 mm fully threaded hex head cap screw to DIN 933 or ISO 4017.

Installation Notes

Installation is performed by mechanics, fabricators, or millwrights using a 24 mm open-end, combination, or socket wrench. Always verify thread engagement depth and mating material specifications before torquing. Follow the applicable engineering or equipment manufacturer torque specification for Grade 8.8 M16 fasteners — do not substitute values from other grade or size classes. Inspect threads for damage before installation and replace any fastener showing signs of galling or cross-threading.
