Value Collection 42715 M4x0.70 Hex Socket Cap Screw 30mm

Product Description

The VALUE COLLECTION 42715 is an M4 x 0.70 hex socket cap screw designed for precision fastening applications requiring high tensile strength and a clean, corrosion-resistant finish. Manufactured from alloy steel with a black oxide coating, this screw meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating an exceptionally high-strength fastener. With a 30 mm length under head and partial threading, it is suited for applications where a clamped grip zone is needed between the threaded and unthreaded sections. Installation requires a hex socket drive. Sold in single packages with a minimum order quantity of 50 units.

This fastener is appropriate for use in mechanical assemblies, machine tooling, equipment manufacturing, and general industrial fabrication where a recessed drive and high clamp load are required. The M4 thread size and 30 mm length under head make it a common choice in compact structural assemblies and precision component mounting. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it suitable for both indoor and controlled-environment outdoor applications.

Key Features

• M4 x 0.70 thread size with 30 mm length under head
• Alloy steel construction rated to material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Partially threaded shank provides a smooth grip zone for precision clamping
• Hex socket (Allen) drive for torque application in tight spaces
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw compatible with M4 x 0.70 threaded assemblies requiring a grade 12.9 alloy steel fastener.

Installation Notes

This fastener is typically installed by machinists, millwrights, or mechanical assembly technicians using a calibrated hex socket driver or Allen key of the appropriate metric size. Always ensure the mating threaded hole or nut is rated to accept a grade 12.9 fastener before installation. De-energize and lock out any equipment before performing fastener service on live machinery. Do not substitute a lower-grade fastener in applications where 12.9 strength class is specified.
