Holo-krome 770610090 Hex Socket Cap Screw M6x1 90mm

Product Description

The HOLO-KROME 770610090 is a metric hex socket cap screw designed for precision fastening applications where corrosion resistance and structural integrity are required. Manufactured to Austenitic Grade A4 stainless steel, this fastener complies with ISO 3506-1 and ISO 4762 standards, making it suitable for demanding environments including marine, chemical processing, and food service installations. The M6 x 1.00 thread pitch and 90mm length under head with partial threading make it well suited for through-hole assemblies and applications requiring a smooth shank section. Tradespeople and maintenance technicians select this fastener when stainless performance and dimensional accuracy to metric ISO standards are required.

This screw is used in mechanical assemblies, equipment fabrication, and maintenance applications across HVAC, plumbing, electrical enclosure work, and general industrial settings. The hex socket drive allows for high torque application in confined spaces using a standard hex key or Allen driver. The partially threaded design provides a consistent clamping grip while the uncoated bright finish keeps the fastener suitable for environments where coating contamination or galvanic interference is a concern.

Key Features

• M6 x 1.00 metric thread with 90mm length under head
• Partially threaded shank for controlled clamping in through-hole applications
• Grade A4 Austenitic stainless steel for strong corrosion resistance
• Hex socket drive for high-torque installation in tight spaces
• Bright uncoated finish meets ISO 3506-1 and ISO 4762 standards
• Minimum order quantity of 5 units per order

Compatibility

Designed as a metric ISO 4762 hex socket cap screw for use in assemblies specifying M6 x 1.00 thread size and Grade A4 stainless steel fasteners per ISO 3506-1.

Installation Notes

Installation is performed using a properly sized metric hex key or Allen driver to prevent socket cam-out and fastener damage. Ensure mating threads are clean and free of debris before installation. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound to the threads when working with stainless-to-stainless assemblies. Disengage power or shut off relevant systems before performing fastener work on energized equipment or pressurized components.
