Holo-krome 76606 Hex Socket Cap Screw M2 X 0.40

Product Description

The HOLO-KROME 76606 is a metric hex socket cap screw with an M2 x 0.40 thread size and a 6 mm length under head. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suited for demanding fastening applications. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity. Fully threaded along its length, this screw is driven with a hex key and is designed for use by mechanical contractors, maintenance technicians, and precision assembly professionals working with metric-fastened assemblies.

This screw is appropriate for light-load, tight-clearance applications where a small-diameter, high-strength metric fastener is required. The M2 thread pitch and compact 6 mm under-head length make it well suited for instrument panels, electronics enclosures, HVAC control housings, small motor assemblies, and similar applications where space is limited and fastener integrity is critical. The 12.9 material grade rating indicates it meets high-strength fastener standards for both static and dynamic load environments.

Key Features

• M2 x 0.40 metric thread, fully threaded under head
• 6 mm length under head for compact, tight-clearance installations
• Alloy steel construction at material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Hex socket drive for precise torque application in confined spaces
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard metric hex socket cap screw suitable for any application requiring an M2 x 0.40 fully threaded fastener conforming to DIN 912 or ISO 4762 specifications.

Installation Notes

Installation is typically performed by mechanical assemblers, HVAC technicians, or maintenance technicians using a calibrated hex key or hex bit driver sized for M2 socket cap screws. Always de-energize and lock out any equipment before replacing or installing fasteners on powered assemblies. Do not mix metric and imperial fasteners in the same tapped hole. Verify thread engagement depth is appropriate for the base material to avoid stripping or under-torquing at this screw diameter.
