Holo-krome 770407006 M4x0.70 Hex Socket Cap Screw 6mm

Product Description

The HOLO-KROME 770407006 is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, equipment fabrication, and industrial maintenance applications. It features an M4 x 0.70 thread size with a 6 mm length under head and is fully threaded along its entire shank. The drive type is internal hex, requiring a standard hex key or Allen wrench for installation. Constructed from austenitic Grade A4 stainless steel with a bright, uncoated finish, this screw resists corrosion in wet and chemically exposed environments. It conforms to ISO 3506-1 and ISO 4762 fastener standards, making it suitable for applications where dimensional consistency and material traceability are required.

This screw is used in applications where a compact, low-profile fastener with high corrosion resistance is needed. Typical installations include marine equipment, food processing machinery, medical devices, cleanroom assemblies, and outdoor structural components. The M4 thread size makes it appropriate for light-duty mechanical assemblies where space is limited and precise thread engagement is critical. Machinists, millwrights, equipment technicians, and industrial maintenance professionals commonly use this type of fastener when working with metric-dimensioned components.

Key Features

• M4 x 0.70 metric thread size with 6 mm length under head
• Fully threaded shank for maximum thread engagement in thin materials
• Austenitic Grade A4 stainless steel construction for superior corrosion resistance
• Bright, uncoated finish — no surface treatment that could affect dimensional tolerances
• Internal hex drive for high torque application in confined spaces
• Conforms to ISO 3506-1 and ISO 4762 international fastener standards

Compatibility

Designed as a standard ISO 4762 metric hex socket cap screw suitable for use in any application requiring an M4 x 0.70 fully threaded cap screw in Grade A4 stainless steel.

Installation Notes

Installation is performed with the appropriate metric hex key sized for the M4 socket head. Ensure mating threaded holes are clean and free of debris before installation. Grade A4 stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes. Follow applicable industry torque guidelines for M4 stainless fasteners as specified by the equipment manufacturer or applicable mechanical codes.
