Yahata Neji Black Oxide Steel Hex Socket Cap Screw M4 x 25 mm M4X25

Yahata Neji M4X25 Black Oxide Steel Hex Socket Cap Screw is a high tensile 12.9 grade socket screw designed for demanding mechanical applications where strength is critical and corrosion resistance is minimal. The hex socket cap head allows it to fit into confined spaces where normal hex bolts cannot be used.

Manufactured in Japan with precise metric threads according to DIN 912 and ISO 4762 standards, this screw is ideal for machine tooling, repair, and maintenance projects in industrial environments. Its compact form factor and strong steel build enable reliable fastening in security guarding, domestic, and facilities maintenance applications.

The black oxide finish subtly enhances surface durability and protects against mild corrosion, although it is not intended for highly corrosive environments. Installation requires a hex key (Allen wrench), ensuring tight and secure fitting.

This socket screw is part of a broader range of hex socket cap screws offered in various sizes and finishes, including self-colour steel, BZP steel, titanium, and stainless steel grades A2 (304) and A4 (316), all conforming to DIN standard 912. These options allow selection of the appropriate material and finish to meet specific industrial requirements.
