Value Collection 643121PS M12 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643121PS is a fully threaded hex head cap screw designed for metric fastening applications in industrial, mechanical, and structural assemblies. Sized at M12 x 1.75 with a 40 mm length under head, this fastener is manufactured from Grade 8.8 steel with a bright, uncoated finish. The 19 mm hex drive allows installation with standard metric wrenches or sockets. Conforming to DIN 933 and ISO 4017 standards, it suits applications where dimensional precision and load-rated fastener grades are required. Machinists, millwrights, equipment technicians, and maintenance mechanics commonly specify this screw in replacement and assembly work.

This cap screw is suited for general-purpose metric bolted connections in manufacturing equipment, machinery frames, structural brackets, and mechanical assemblies. The fully threaded shank provides maximum thread engagement across the clamped joint. The uncoated finish is appropriate for indoor or controlled-environment installations where corrosion resistance is not a primary requirement. Grade 8.8 tensile rating makes it a common choice for medium-to-high strength fastening needs throughout industrial and OEM assembly environments.

Key Features

• Fully threaded shank for maximum thread engagement in the joint
• Grade 8.8 steel construction provides reliable medium-to-high tensile strength
• Conforms to DIN 933 and ISO 4017 standards for dimensional consistency
• 19 mm hex size compatible with standard metric hand tools and power tools
• Bright, uncoated finish suitable for controlled indoor environments

Compatibility

Designed as an OEM-style metric replacement fastener for machinery, equipment frames, and structural assemblies requiring M12 x 1.75 thread specification per DIN 933 and ISO 4017.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using a 19 mm metric wrench or socket. Ensure the mating thread is clean and free of debris before installation. Always de-energize or lock out equipment before replacing fasteners in live mechanical systems. Do not exceed the rated clamp load for Grade 8.8 fasteners or mix metric and unified thread components.
