Value Collection A996728 M4 X 0.70 Hex Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION A996728 is an M4 x 0.70 hex socket cap screw designed for precision fastening applications where high tensile strength and a clean, low-profile head are required. Manufactured from alloy steel to material grade 12.9 and finished with a black oxide coating, this screw delivers reliable clamping force in demanding mechanical assemblies. The 55 mm length under head and partial threading allow for accurate thread engagement in tapped holes. It meets DIN 912 and ISO 898-1 fastener standards, making it suitable for use in machine assemblies, tooling fixtures, and industrial equipment. Installation requires a hex (Allen) key driver. The package includes 25 pieces per unit.

This screw is suited for mechanical, maintenance, and fabrication professionals working on machine frames, jigs, fixtures, and structural assemblies that require a high-strength metric fastener. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision environments. The M4 x 0.70 thread pitch is a standard metric coarse thread widely used in light machinery, electronics housings, and instrumentation panels. The partial threading is appropriate for applications where the unthreaded shank must bear shear loads or span clearance holes before engaging the threaded portion of the assembly.

Key Features

• M4 x 0.70 metric coarse thread for standard tapped hole compatibility
• 55 mm length under head for deep-reach fastening in thick materials
• Partially threaded shank for shear load bearing and clearance hole applications
• Alloy steel grade 12.9 construction for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Meets DIN 912 and ISO 898-1 standards for consistent dimensional and mechanical compliance

Compatibility

Designed as a standard DIN 912 hex socket cap screw for use in any M4 x 0.70 tapped hole requiring a grade 12.9 alloy steel fastener with a 55 mm length under head.

Installation Notes

Installation is performed with the appropriate metric hex key or hex bit driver sized for the M4 socket cap head. Verify the tapped hole thread pitch and depth before installation to ensure full thread engagement with the partial threading. Grade 12.9 fasteners are susceptible to hydrogen embrittlement and should not be used in strongly acidic environments without engineering review. Follow applicable torque specifications from the equipment manufacturer or recognized fastener standards when torquing to final value.
