Holo-krome 77044 M4 X 0.70 Hex Socket Cap Screw 8mm

Product Description

The HOLO-KROME 77044 is a metric hex socket cap screw designed for applications requiring a compact, recessed-drive fastener in corrosion-resistant stainless steel. Sized M4 x 0.70 with an 8 mm length under head, this screw is fully threaded from tip to head. It is manufactured to Austenitic Grade A4 stainless steel, which provides strong resistance to corrosion and oxidation in demanding service environments. The bright, uncoated finish leaves the base material exposed and is typical for applications where dimensional consistency and surface integrity matter. Technicians in HVAC, plumbing, electrical, and general mechanical assembly install this fastener wherever a socket-drive cap screw is specified.

This fastener is suited for light mechanical assemblies, equipment panels, enclosures, and component mounting applications across residential and commercial trade work. The M4 x 0.70 thread pitch is a standard metric coarse thread, commonly encountered in imported equipment, VFDs, control panels, and small mechanical assemblies. Its fully threaded shank allows maximum thread engagement even in shallow tapped holes or when used with a nut.

Key Features

• M4 x 0.70 metric coarse thread for broad compatibility with standard metric tapped holes
• 8 mm length under head, fully threaded for maximum engagement depth
• Austenitic Grade A4 stainless steel construction for corrosion resistance
• Hex socket (Allen) drive for use with standard hex keys or bit drivers
• Bright, uncoated finish — no additional coating thickness to affect fit
• Manufactured to ISO 4762 and ISO 3506-1 fastener standards

Compatibility

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

Installation Notes

Install using a correctly sized metric hex key or socket bit to avoid cam-out and drive damage. Ensure the mating tapped hole or nut is clean and free of debris before driving. De-energize any electrical equipment and relieve system pressure before accessing fastened assemblies in live HVAC, plumbing, or electrical installations. Do not mix with carbon steel fasteners in wet or corrosive environments, as galvanic reactions can compromise joint integrity.
