Value Collection 643130PR Hex Head Cap Screw M12x1.75x55mm

Product Description

The VALUE COLLECTION 643130PR is a metric hex head cap screw sized M12 x 1.75 with a 55 mm length under the head. It is fully threaded from the head to the tip and machined from Grade 8.8 steel with a bright, uncoated finish. The 19 mm hex drive size is compatible with standard metric wrenches and sockets. This fastener meets DIN 933 and ISO 4017 standards, making it suitable for structural and mechanical assemblies where a verified material grade and thread standard are required. Installers in HVAC, plumbing, electrical, and general mechanical trades rely on Grade 8.8 fasteners for dependable clamping force in steel-to-steel connections.

This screw is used in a wide range of industrial and trade applications including equipment mounting, structural framing connections, flanged pipe assemblies, and machinery installation. Its fully threaded shank allows engagement along the entire bolt length, which is useful when threading into tapped holes or when using a nut across the full grip range. The metric M12 x 1.75 thread pitch is a standard coarse thread commonly encountered in European and internationally sourced equipment and components.

Key Features

• Fully threaded shank for maximum thread engagement along the entire 55 mm length
• Grade 8.8 steel construction provides reliable tensile and yield strength for structural fastening
• 19 mm hex head fits standard metric wrenches and impact sockets
• Bright, uncoated finish — suitable for dry indoor environments or where a coating will be applied in the field
• Meets DIN 933 and ISO 4017 standards for dimensional and mechanical compliance
• Coarse M12 x 1.75 thread pitch — widely used in metric mechanical and structural assemblies

Compatibility

Designed for use in metric-threaded applications requiring an M12 x 1.75 coarse-pitch hex head cap screw conforming to DIN 933 and ISO 4017 dimensional standards.

Installation Notes

This fastener should be installed by a qualified mechanic or trade professional using a calibrated torque wrench to achieve the appropriate clamp load for the joint design. Always verify thread engagement depth and mating thread condition before installation. Power down and de-energize any equipment before accessing fastener locations on electrical or mechanical assemblies. Do not mix metric and imperial fasteners in the same joint.
