Value Collection 643549PR M4 Hex Cap Screw 8.8 Steel Din 933

Product Description

The VALUE COLLECTION 643549PR is a metric hex head cap screw designed for general mechanical fastening in assemblies that require a fully threaded fastener. It is manufactured from Grade 8.8 steel with a bright, uncoated finish, making it suitable for indoor and controlled-environment applications. The screw measures M4 x 0.70 thread pitch with a 40 mm length under head and is driven by a 7 mm hex head. It conforms to DIN 933 and ISO 4017 standards. Maintenance technicians, machine builders, and fabricators install this fastener in light-duty structural and mechanical connections.

This screw is used in metric-standard assemblies across a range of industries including HVAC equipment fabrication, light machinery, electrical enclosures, and general manufacturing. Its fully threaded shank allows engagement along the entire length, making it effective in thin-material applications or where maximum thread engagement is required. The DIN 933 and ISO 4017 compliance ensures dimensional consistency with metric hardware from other manufacturers.

Key Features

• Fully threaded shank provides maximum thread engagement across the entire fastener length
• Grade 8.8 steel construction delivers reliable tensile and yield strength for mechanical assemblies
• Bright uncoated finish maintains close dimensional tolerances for precision fitting
• Conforms to DIN 933 and ISO 4017 standards for interchangeability with metric fastener systems
• 7 mm hex head is compatible with standard metric hex wrenches and sockets

Compatibility

Designed as a DIN 933 and ISO 4017 compliant metric hex head cap screw suitable for M4 x 0.70 threaded holes in steel, aluminum, and other materials requiring a fully threaded fastener.

Installation Notes

Installation is performed with a standard 7 mm metric hex wrench or socket. Ensure the mating thread is clean and free of debris before driving the fastener. Do not exceed the rated mechanical limits of Grade 8.8 hardware by over-torquing. Always follow applicable equipment manufacturer specifications and relevant fastener standards when selecting and installing fasteners in load-bearing assemblies.
