Value Collection 42708 M4x0.70 Hex Socket Cap Screw 8mm

Product Description

The VALUE COLLECTION 42708 is a metric hex socket cap screw designed for fastening applications requiring a compact, high-strength threaded connection. The screw features an M4 x 0.70 thread specification with 8 millimeters of length under the head and is fully threaded along its shank. Built from alloy steel to material grade 12.9, it delivers high tensile and proof-load strength suitable for demanding mechanical assemblies. A black oxide finish provides mild corrosion resistance and a clean, uniform appearance. This fastener conforms to DIN 912 and ISO 898-1 standards. Installed with a standard hex key or Allen wrench, it is used by machinists, millwrights, equipment technicians, and maintenance mechanics.

The 42708 is suited for precision mechanical assemblies, machine tool frames, jigs, fixtures, and general industrial equipment where a recessed-drive, low-profile cap screw is required. The fully threaded shank allows the fastener to engage threads across its full length, making it appropriate for shallow-clearance tapped holes. This part is sold in a minimum order quantity of 50 pieces per package, making it practical for production and maintenance stock replenishment.

Key Features

• M4 x 0.70 thread size for standard metric fastening applications
• 8 mm length under head, fully threaded shank for maximum thread engagement
• Alloy steel construction rated to material grade 12.9 for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Hex socket drive accepts standard metric Allen keys or hex bit drivers
• Conforms to DIN 912 and ISO 898-1 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or production fastener for any application requiring a DIN 912 compliant M4 x 0.70 metric hex socket cap screw with an 8 mm length under head.

Installation Notes

Installation requires a correctly sized metric hex key or Allen-drive socket to avoid rounding the socket recess. Always verify the tapped hole thread specification matches M4 x 0.70 before installation. Follow applicable machinery or equipment torque guidance for grade 12.9 fasteners; do not substitute a lower-grade fastener in a grade 12.9 application. Wear appropriate hand protection when handling black oxide finished fasteners in quantity.
