Holo-krome 770610040 M6 X 1.00 Hex Socket Cap Screw 40mm

Product Description

The HOLO-KROME 770610040 is a metric hex socket cap screw designed for secure, high-torque fastening in precision assemblies and mechanical applications. The M6 x 1.00 thread profile and 40 mm length under head make it well suited for medium-depth fastening where a clean, recessed drive finish is required. Constructed from austenitic Grade A4 stainless steel with a bright, uncoated finish, it resists corrosion in wet, marine, and chemically exposed environments. The partially threaded shank provides shear strength and alignment control. This fastener conforms to ISO 3506-1 and ISO 4762 standards and is installed using a standard hex key (Allen wrench).

This screw is used across a broad range of professional and industrial applications including HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and pool and water treatment equipment. The Grade A4 stainless steel material makes it appropriate for outdoor, high-humidity, and saltwater-adjacent environments where carbon steel fasteners would corrode. It is sold in a minimum order quantity of 5 pieces and is suitable for any trade professional requiring metric fasteners that meet ISO dimensional and material standards.

Key Features

• M6 x 1.00 thread size with 40 mm length under head for consistent medium-depth engagement
• Partially threaded shank improves shear resistance and part alignment
• Austenitic Grade A4 stainless steel construction for corrosion resistance in wet and marine environments
• Bright, uncoated finish with no added coating that could affect dimensional tolerance
• Hex socket (Allen) drive for high-torque installation in confined spaces
• Conforms to ISO 3506-1 and ISO 4762 fastener standards

Compatibility

Designed as a standard ISO 4762 metric hex socket cap screw suitable for any M6 x 1.00 threaded application requiring Grade A4 stainless steel material conformance.

Installation Notes

Installation should be performed by a qualified technician using the correct size hex key to avoid rounding the drive socket. Ensure the mating threaded hole or nut meets the same ISO metric standard to prevent cross-threading or galling, which is especially common with stainless steel fasteners. Apply an anti-galling lubricant or thread compound when threading stainless into stainless to reduce the risk of seizing. Follow applicable torque guidelines for M6 stainless fasteners as specified in the equipment manufacturer's service documentation.
