Holo-krome 77088 M5 X 0.80 Hex Socket Cap Screw Stainless

Product Description

The HOLO-KROME 77088 is a metric hex socket cap screw sized M5 x 0.80 with a 12 mm length under head. It is manufactured from Austenitic Grade A4 stainless steel and left uncoated with a bright finish. The hex socket drive requires an allen key or hex bit driver for installation. Fully threaded along its entire shank length, this fastener is suited for precision clamping applications where consistent torque transfer and corrosion resistance matter. Machinists, maintenance technicians, and field service pros working with stainless assemblies reach for this grade when exposure to moisture or chemicals is a concern.

This screw is used in light mechanical assemblies, machine frames, enclosures, and equipment panels where a low-profile cap head and internal hex drive are preferred over external fastener styles. Grade A4 stainless construction makes it appropriate for marine, food-service, chemical processing, and outdoor environments. It is a standard ISO 4762 socket head cap screw and can be installed wherever that specification is called out on engineering drawings or assembly documents.

Key Features

• M5 x 0.80 thread size with 12 mm length under head
• Fully threaded shank for consistent engagement along full clamping length
• Austenitic Grade A4 stainless steel for strong corrosion resistance
• Bright uncoated finish — no coating thickness to affect thread fit

Compatibility

Designed as an ISO 4762 standard hex socket cap screw. Fits any M5 x 0.80 threaded hole or insert conforming to standard metric thread specifications.

Installation Notes

A licensed mechanic or qualified maintenance technician should verify thread engagement depth and hole condition before installation. Use the correct size hex key or socket bit to avoid rounding the drive recess. De-energize and lock out any equipment before accessing fastener locations on live machinery. Do not mix Grade A4 stainless fasteners with carbon steel hardware in assemblies subject to galvanic corrosion risk.
