Value Collection 643115PR Hex Head Cap Screw M12 X 1.75

Product Description

The VALUE COLLECTION 643115PR is a metric hex head cap screw built to Grade 8.8 steel specifications, intended for general mechanical assemblies and structural fastening applications. With a thread size of M12 x 1.75 and a length under head of 30 mm, this screw is fully threaded along its entire shank. The 19 mm hex drive allows installation with standard open-end, box, or socket wrenches. Grade 8.8 steel provides a reliable balance of tensile strength and ductility for medium-to-high load fastening in non-safety-critical assemblies. The uncoated bright finish makes this screw suitable for indoor or protected environments where corrosion resistance is not a primary requirement.

This fastener is used across a wide range of industrial, mechanical, and equipment assembly applications. It is a common choice for machine frames, brackets, flanges, and general structural connections where metric fasteners are specified. Machinists, millwrights, maintenance technicians, and mechanical contractors install this type of screw wherever DIN 933 or ISO 4017 fully threaded hex cap screws are called out on engineering drawings or maintenance specs. It is sold individually with a minimum order quantity of 100 pieces.

Key Features

• Fully threaded shank for maximum thread engagement across the full 30 mm length under head
• Grade 8.8 steel construction delivers medium-high tensile strength for demanding mechanical assemblies
• M12 x 1.75 metric thread conforms to standard metric coarse pitch specifications
• 19 mm hex head accommodates standard wrenches and sockets without special tooling
• Meets DIN 933 and ISO 4017 dimensional standards for broad interchangeability
• Bright uncoated finish for use in dry or protected indoor environments

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant fully threaded hex head cap screw, compatible with any M12 x 1.75 metric coarse threaded hole or nut conforming to those standards.

Installation Notes

Installation is performed by machinists, maintenance technicians, or mechanical contractors using a 19 mm wrench or socket. Always ensure the mating threads are clean and free of debris before installation. Do not exceed the rated load capacity for Grade 8.8 fasteners as defined by the applicable engineering specification or relevant standards. Follow applicable equipment manufacturer torque specifications when tightening into tapped holes or with mating nuts.
