Holo-krome 77110 M5x0.80 Hex Socket Cap Screw 40mm Ss

Product Description

The HOLO-KROME 77110 is a metric hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies and industrial applications. Manufactured from austenitic Grade A4 stainless steel, this screw delivers excellent corrosion resistance without a coating, making it well-suited for wet, chemical-exposed, or outdoor environments. The M5 x 0.80 thread pitch and 40 mm length under head make it a compact yet capable fastener for precision equipment, pump housings, enclosures, and structural panel work. A hex socket drive allows for controlled torque application in tight clearance areas using a standard hex key or Allen driver. It conforms to ISO 4762 and ISO 3506-1 fastener standards.

This screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, pump and motor mounting, electrical enclosure fabrication, and general mechanical maintenance. The partially threaded shank provides shear strength at the joint interface, making it appropriate where load-bearing clamping force is required. Installers in light commercial and industrial settings will find this fastener compatible with standard metric tapped holes in steel, aluminum, and plastic substrates.

Key Features

• M5 x 0.80 metric thread for use with standard M5 tapped holes
• 40 mm length under head with partial threading for shear-load applications
• Grade A4 austenitic stainless steel construction for corrosion resistance
• Bright uncoated finish — no plating to flake, chip, or affect dimensional tolerances
• Hex socket drive for access in confined spaces with a standard hex key
• Conforms to ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed as a standard ISO 4762 metric hex socket cap screw for use in any M5 x 0.80 tapped hole application requiring Grade A4 stainless steel fasteners.

Installation Notes

Installation requires a properly sized metric hex key or bit driver rated for socket cap screws. Verify the mating tapped hole is M5 x 0.80 and free of debris or cross-threading before driving. When installing stainless fasteners into stainless threaded components, apply anti-seize compound to reduce the risk of galling. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes for the assembly type.
