Value Collection 643148PR Hex Head Cap Screw M12x1.75x100mm

Product Description

The VALUE COLLECTION 643148PR is a fully threaded metric hex head cap screw designed for general industrial fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener meets DIN 933 and ISO 4017 standards. It features an M12 x 1.75 thread profile with 100 mm of length under the head and a 19 mm hex drive. Grade 8.8 steel provides a reliable balance of tensile strength and ductility suited to medium- and high-load bolted assemblies. Machinists, millwrights, and maintenance technicians commonly install this fastener across structural, mechanical, and equipment applications.

This cap screw is used in metric-dimensioned assemblies where full thread engagement is required along the entire bolt shank. Typical applications include machinery fabrication, structural steel connections, equipment mounting, and general MRO work. The fully threaded design allows for maximum thread engagement in through-hole or nut-and-bolt configurations. It is appropriate for both indoor and controlled-environment outdoor assemblies where an uncoated finish is acceptable.

Key Features

• M12 x 1.75 metric thread profile with full threading along the 100 mm shank
• Grade 8.8 steel construction for reliable tensile and yield strength in structural applications
• 19 mm hex head drive compatible with standard metric wrenches and sockets
• Meets DIN 933 and ISO 4017 dimensional and material standards
• Bright uncoated finish suitable for assemblies that do not require corrosion protection

Compatibility

Designed as a standard metric hex head cap screw per DIN 933 and ISO 4017 for use in metric-threaded through-hole assemblies requiring an M12 x 1.75 thread pitch.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using standard metric hand or power tools. Always verify thread pitch and hole diameter before installation to prevent cross-threading. Uncoated steel fasteners should not be used in high-moisture or corrosive environments without additional protection. Torque to the value specified by the equipment manufacturer or relevant structural standard for Grade 8.8 metric fasteners.
