Holo-krome 76604 Hex Socket Cap Screw M2 X 0.40 Metric

Product Description

The HOLO-KROME 76604 is a metric hex socket cap screw designed for precision fastening in industrial, mechanical, and trade applications. Sized M2 x 0.40 with a 4 mm length under head, this screw is fully threaded and features an internal hex drive for torque transmission in tight clearances. Manufactured from alloy steel at material grade 12.9, it delivers high tensile strength suited to demanding assemblies. The black oxide finish provides moderate corrosion resistance and reduces surface reflectivity. Licensed trades, maintenance technicians, and mechanical assemblers commonly install this fastener where compact, high-strength metric hardware is required.

This fastener is used across a wide range of light-duty to heavy-duty assemblies wherever an M2 metric thread pitch of 0.40 is specified. Typical applications include precision equipment, instrumentation, HVAC component assemblies, electrical enclosures, and machinery sub-assemblies. The small M2 form factor makes it well suited to confined mounting locations. Conformance to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 ensures dimensional and mechanical interchangeability with standard metric socket cap screw specifications globally.

Key Features

• M2 x 0.40 metric thread, fully threaded from tip to head
• 4 mm length under head for shallow-profile fastening
• Alloy steel construction at grade 12.9 for high tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and low-glare surface
• Hex socket (Allen) drive allows installation in recessed or confined locations
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric socket cap screw, compatible with any M2 x 0.40 threaded hole requiring a grade 12.9 alloy steel fastener.

Installation Notes

Install using a correctly sized hex key or Allen driver to avoid rounding the socket; do not use an oversized or worn driver. Confirm thread engagement depth is adequate for the material being fastened before applying torque. Minimum order quantity for this part is 10 pieces per order. Follow applicable mechanical assembly codes and equipment manufacturer torque guidelines when specifying grade 12.9 hardware in critical joints.
