Holo-krome 770508070 Hex Socket Cap Screw M5 X 0.80

Product Description

The HOLO-KROME 770508070 is a metric hex socket cap screw designed for precision fastening applications requiring corrosion resistance and reliable clamping strength. It features an M5 x 0.80 thread profile with a 70 mm length under head and is partially threaded along the shank. Manufactured from Austenitic Grade A4 stainless steel with a bright, uncoated finish, this screw meets ISO 4762 and ISO 3506-1 standards. It is driven with a hex key (Allen wrench) socket and is suited for mechanical assemblies, instrumentation, food-grade equipment, and marine or outdoor environments where stainless material is required.

This screw is commonly used in light to medium-duty mechanical assemblies across HVAC equipment panels, plumbing fixture hardware, electrical enclosure construction, and general industrial fabrication. The partial thread design allows the unthreaded shank to bear shear loads in close-tolerance bored holes, making it appropriate for precision-aligned component joins. Installers in both commercial and residential trade settings will find this fastener suitable wherever an M5 metric thread pattern is specified and corrosion resistance is a priority.

Key Features

• M5 x 0.80 metric thread size for standard metric fastening applications
• 70 mm length under head with partial threading for shear-load and precision-alignment joints
• Austenitic Grade A4 stainless steel construction for high corrosion resistance
• Bright uncoated finish maintains dimensional accuracy and clean appearance
• Hex socket drive for high torque input in confined or recessed spaces
• Meets ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed as a direct-fit metric fastener for assemblies specifying an M5 x 0.80 hex socket cap screw per ISO 4762. Suitable for use in stainless-compatible tapped holes and threaded inserts with M5 x 0.80 internal thread.

Installation Notes

Installation should be performed by a qualified technician or tradesperson using a properly sized hex key or socket driver rated for the M5 drive recess. Ensure the mating tapped hole or threaded insert is clean and free of debris before installation. Do not exceed the designed torque range for M5 stainless fasteners, as over-torquing Grade A4 stainless can cause galling; use appropriate anti-galling compound when specified by the assembly design. Always de-energize or shut off systems before accessing panels or enclosures where this fastener is being installed or replaced.
