Value Collection 643139PR M12x1.75x70mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643139PR is a fully threaded metric hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, it measures M12 x 1.75 thread pitch with a 70 mm length under the head and a 19 mm hex drive. Grade 8.8 indicates a medium-high strength carbon steel fastener capable of handling substantial clamping loads. This screw conforms to DIN 933 and ISO 4017 standards, making it a reliable choice where metric fastener specifications must be met precisely. Technicians, millwrights, and maintenance professionals working on equipment assemblies, structural fixtures, and machinery will find this a straightforward replacement or new-build fastener.

This hex head cap screw is suited for use in industrial machinery, structural steel connections, equipment mounting, and general mechanical assemblies requiring a metric M12 fully threaded fastener. The uncoated finish is appropriate for dry indoor environments or applications where a secondary coating or plating will be applied post-installation. Compliance with DIN 933 and ISO 4017 ensures dimensional consistency across international manufacturing and repair contexts. Available in multiples of 50 per order to support production and maintenance operations requiring bulk quantities.

Key Features

• Fully threaded M12 x 1.75 metric thread profile along the entire 70 mm shank length
• Grade 8.8 steel construction provides reliable tensile and yield strength for medium-high load applications
• 19 mm hex head fits standard metric wrenches and sockets for straightforward installation and removal
• Conforms to DIN 933 and ISO 4017 standards for dimensional accuracy and interchangeability
• Bright uncoated finish suitable for controlled environments or where post-install coatings will be applied

Compatibility

Designed as a standard metric replacement or new-installation fastener for any assembly specifying an M12 x 1.75 x 70 mm fully threaded hex head cap screw per DIN 933 or ISO 4017.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or maintenance technicians using a standard 19 mm metric wrench or socket. Ensure mating threads are clean and free of debris before assembly. De-energize and lock out any equipment before fastener replacement per applicable OSHA lockout/tagout procedures. Do not exceed the torque values specified by the equipment manufacturer for M12 Grade 8.8 fasteners in the relevant joint design.
