Holo-krome 770508045 M5x0.80 Hex Socket Cap Screw 45mm

Product Description

The HOLO-KROME 770508045 is a metric hex socket cap screw with an M5 x 0.80 thread and a 45 mm length under head. It is manufactured from austenitic Grade A4 stainless steel with a bright, uncoated finish. The screw is partially threaded and driven by a standard hex (Allen) key. This fastener conforms to ISO 4762 and ISO 3506-1 standards, making it suitable for corrosion-resistant mechanical assemblies. It is installed by licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and light-industrial equipment applications where stainless fasteners are required.

This screw is commonly used in equipment assembly, panel mounting, and structural fastening tasks where metric threading and corrosion resistance are required. The Grade A4 stainless steel construction makes it appropriate for wet, marine, or chemically aggressive environments where carbon steel fasteners would be unsuitable. It is sold in a minimum order quantity of 10 pieces per order increment.

Key Features

• M5 x 0.80 metric thread for precise engagement in tapped metric holes
• 45 mm length under head for deeper fastening reach
• Partially threaded shank for shoulder-style clamping applications
• Austenitic Grade A4 stainless steel for excellent corrosion resistance
• Bright, uncoated finish with no added plating that could affect dimensional tolerances
• Complies with ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed for use in tapped M5 x 0.80 metric threaded holes in accordance with ISO 4762 and ISO 3506-1 specifications. Suitable as a direct replacement in any assembly calling for a Grade A4 stainless steel hex socket cap screw of this thread and length.

Installation Notes

Install using the correct-size hex key or hex bit driver to avoid rounding the socket drive. Ensure the receiving hole is properly tapped to M5 x 0.80 before installation. Do not over-torque stainless fasteners, as galling can occur; applying an appropriate anti-seize compound to the threads is a common field practice. Power down or de-energize equipment fully before accessing fastener locations on live assemblies.
