Holo-krome 76612 M2 X 0.40 Metric Hex Socket Cap Screw

Product Description

The HOLO-KROME 76612 is a metric hex socket cap screw in M2 x 0.40 thread size with a 12 mm length under head. Made from grade 12.9 alloy steel with a black oxide finish, this fastener is engineered for high-strength clamping applications where a low-profile socket drive is required. The fully threaded shank and black oxide coating provide corrosion resistance and reduce galling during installation. Manufactured to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards, this screw is suited for precision assemblies where dimensional consistency and tensile strength are critical.

This screw is used in machine assembly, tooling fixtures, equipment manufacturing, and maintenance applications requiring a compact hex socket drive in tight clearance areas. The M2 thread size and 12 mm under-head length make it a common choice for small-scale mechanical assemblies, instrumentation panels, and light structural connections. Licensed machinists, millwrights, and maintenance technicians are the typical installers. It is sold in multiples of 100 pieces per minimum order.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Fully threaded shank along the entire 12 mm under-head length
• Hex socket (Allen) drive type for use in confined spaces with a hex key or driver bit
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock metric hex socket cap screw for any assembly requiring an M2 x 0.40 thread, 12 mm under-head length, DIN 912 or ISO 4762 compliant fastener.

Installation Notes

Installation is performed with a correctly sized hex key or socket driver matched to the M2 cap screw drive specification. Ensure mating threaded holes are clean and free of debris before installation. Do not exceed the rated torque range for grade 12.9 M2 fasteners as specified in the applicable engineering standard or assembly documentation. Black oxide finish offers only mild corrosion protection and is not a substitute for additional coating or plating in wet or caustic environments.
