Holo-krome 77048 M4x0.70 Hex Socket Cap Screw Stainless

Product Description

The HOLO-KROME 77048 is a metric hex socket cap screw designed for precision fastening applications where a low-profile, high-strength connection is required. This screw features an M4 x 0.70 thread size with a 10 mm length under head and is fully threaded along its entire shaft. The drive type is a standard hex socket, compatible with a hex key or Allen driver. Manufactured from austenitic Grade A4 stainless steel with a bright, uncoated finish, the 77048 is well suited for environments where corrosion resistance is a priority. Mechanical and maintenance technicians, machine builders, and fabricators regularly specify this fastener for clean, recessed-drive assemblies.

This screw is appropriate for light-duty to medium-duty bolted joints in industrial, marine, food-processing, and general-purpose equipment where stainless steel hardware is called out by design or maintenance specs. The fully threaded configuration makes it useful in thin-material applications where thread engagement along the full length is needed. It meets ISO 4762 dimensional standards and ISO 3506-1 material requirements for stainless fasteners, making it an accepted choice for engineered assemblies with documented fastener standards.

Key Features

• M4 x 0.70 thread pitch, fully threaded for maximum engagement in thin stock
• 10 mm length under head for compact, low-profile installations
• Hex socket drive accepts standard hex key or Allen wrench tooling
• Austenitic Grade A4 stainless steel for strong corrosion resistance
• Bright uncoated finish — no coating to crack, flake, or interfere with tight tolerances
• Conforms to ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed as a metric hex socket cap screw conforming to ISO 4762 dimensions and ISO 3506-1 material grade requirements, suitable for use in any application specifying an M4 x 0.70 x 10mm fully threaded stainless steel socket head cap screw.

Installation Notes

Install using a properly sized metric hex key or Allen driver to avoid rounding the socket drive. Ensure mating threads in the receiving hole are clean and free of debris before installation. De-energize, depressurize, or otherwise isolate equipment before replacing or installing fasteners in live assemblies. Consult applicable equipment torque specifications from the equipment manufacturer — do not estimate torque values for stainless fasteners, as galling is a known failure mode if over-torqued without lubrication.
